Night vision

how to view a pdf file in night vision on a mac desktop similar to android on a mobile ?

Hello kmccmk9
iGlasses 2 offers manual control of some camera settings. One of these is low-light capability that they call "Night Vision." You can take advantage of their free trial to see if it works better than what you already have before you buy.
Contrary to what the iGlasses ad claims, nothing but some kind of lighting device can give you vision in "total darkness", but iGlasses can let you see in light at the lowest levels that your iSight can use.
If you decide not to buy iGlasses, be sure to uninstall it by following the instructions from ecamm. Do not just ignore or throw it away or you may find the the expired trial version causes some strange behavior. You shouldn't be concerned about this cautionary comment. iGlasses is good, reasonably priced, reliable software if you want the features it offers. I include this caution only because some users who ignored the demo expiration or failed to uninstall completely have reported strange problems after the trial expired.
If you need lower light capability than iGlasses gives or plan to use your iSight in a cave or some other real "total darkness" situation, use SteveyJ's suggestions and look for a special-purpose IR camera.

My cat sat on my keyboard and now my desktop display looks like it is in night vision with color. How do I get it back to it's original display?

My cat sat on my keyboard and changed the display. Now the coloration and brightness looks like it is in night vision with a bit of color. It is similar to one of the photo booth effect options. How do I get it back to normal?

Hi JoeBeth,
Welcome to the Apple Support Communities!
It sounds like your colors have become inverted on your display. This is a feature of Universal Access. Please refer to the attached article for information on this feature with instructions to toggle it on and off.
Mac OS X displays inverted image colors (white on black, reverse type)
Have a great day,

Connecting Digital Night Vision to Mac

Hello
I wasted money on an RCA to USB converter to connect my Yukon Ranger Digital Night Vision Monocular to my Mac to record video of what it captures.
Is there any WORKING way I can do this?
The Night Vision has an RCA female output ( works on my LCD TV ) so I need a converter that can allow me to input this in my new Quad Core iMac, any way possible.
anything available??
thanks
Anthony

How do you add night vision to a film?

I have to make a movie for my english class and it's suppose to be like Ghost Adventures. However, my camera doesn't have night vision on it. Is there anyway I can add night vision through iMovie?

Not really, but in iMovie 11 you can use effects to add the SciFi look and video adjustments to make it green. Can't remember if those were in 09.

My pictures look like they are in night vision

My Ipad's camera appears like it's in night vision mode. I don't know if there is such a thing, but that's what it looks like. I can't find any option button to change it. Also, all photos that I look at in my email, from others, look the same way. Help please.

Check Settings -> General -> Accessibility -> Invert Colors and turn this OFF. Pre iOS 6 this is called White on Black.

All my apps with camera or videocams are in night vision. Help!

Camera stuck with night vision type effect

My camera worked fine for a few days, but now it's stuck with some type of effect that looks like a night vision infrared mode or something. It's all green, and the luma values look like they're reversed or something. It looks that way both on the iphone display, and in the finished picture. I don't see any settings that effect the camera (there are some for photos, but not the actual camera)- do I have some sort of effect turned on, or is it broken? Thanks...

the only other thing you can try is restoring the software of the iPhone, This will wipe out the info (Only on the iPhone) If that does not resolve the issue then it will need to be serviced either By calling Apple or Going to a Apple Retail Store.
If you sync to one computer everything should still be on the computer and would sync back up.

How do you create your own theme?

I'm into astronomy and I'd like to create my own theme on my phone (6300) for when I'm at a dark site. We use red light only at dark sites because white light ruins your night vision for longer. How can I create a red-based colour theme/wallpaper/text etc?

Actually, the .nth files used as themes for S40 phones such as the 6300 are very simple and you don't really need any software other than a text editor to create them.
These .nth files are in fact renamed .zip files. Rename one back to a .zip file, unzip it and look at the structure. At the core of it you have a simple XML file describing the various aspects of the theme. If any media (wallpaper, screensaver, ringtone etc.) is referred to in the XML file it'll be bundled in the archive along with the XML.
Make any changes you want, zip the lot up again, rename it as a .nth file and you're done.

Camera Viewfinder - Display Issues

BB 8100 Smartphone (EDGE) v4.5.0.110 (Platform 2.7.0.90)
Updated to new version firmware last night to get MMS capability and try to remove sepia like view from camera screen display when taking pictures. Halfway successful - Can now send MMS with photo attachment.
Camera still shows sepia like viewfinder. Sort of like night vision or infrared thermal imaging. No Option tab in camera settings to select different display or picture mode - eg. Normal, B&W or sepia.
here are camera setting:
Default Flash - automatic
White Balance - auto
Pic Size - LG (1280 x 1024)
Pic Quality - Superfine
Store pics - device memory
Is problem with camera hardware or maybe new software will fix?
Pictures turn out fine (were really blurry but improved greatly when I carefully cleaned the lens )

Complete failure of PC app

This is the story of why I would not recommend the PC app to others and would instead encourage them to use steam, gamestop, or finally actually just going to the store. It started when I installed the app and a few games. I realized I was running out of hard drive space on my small SSD (120 GB) and wanted to install games on my other hard drive (2TB). I contacted live support and they told me geek squad would be able to help me. The first time I contacted geek squad was to try and figure out how to install games into a new location which lots of applications are able to do (iTunes, gamestop app, steam, etc.) and they told me that due to faulty/bad coding you aren't able to do that. I was a little frustrated at first but it wasn't awful, and so I uninstalled the app along with the 2 15+ GB games I had. After I tried to re install it, the PC installer kept insisting that I needed to repair the PC app program and not install it. I contacted the geek squad a second time and this time they told me the only way to uninstall it was to do add/remove programs, which I had already done. I did a little googling while on hold and figured out that the app has lots of hidden folders and miscellaneous folders scattered throughout my SSD. By the time the geek squad member got back on the phone I was told I needed to reinstall it and unistall it to fix the problem. I finished doing that and it just left me where I started and didn't solve anything. At this point I didn't want to contact them anymore due to lack of knowledge and tried to fix the problem myself by using add/remove programs and deleting all the hidden/miscellaneous files around my SSD. I downloaded a fresh copy of the installer from the website and, much to my annoyance, it wanted to repair the application instead of reinstall it . The worse part about it this time was that it would not let me completely reinstall the program, stating that I was missing some files or needed to locate them. I thought this was odd because I was repairing the program so it would replace missing files and if all the files were missing it would just reinstall a fresh copy. So now I am left with $130 of unplayable games purchased through this worthless app and would like either a refund, or hard copies of the games I tried to download to avoid this god-awful program.

This program is indeed one of the most poorly written pieces of software I've used.
I know this topic is old, but hopefully this will help a few people:
The BBY pc app installer contains an MSI (Windows Installer) package that is the cause of the issue the OP describes. The uninstaller leaves the Windows Installer package behind, and subsequent installs attempt to repair the existing package since it was never removed.
BBY PC App can be fully removed (I've done it for several friends), but it is a complex process. The directions below assume you have an understanding of Windows Explorer.
These directions are provided as-is. Use them at your own risk.They worked for me, but there's no guarantee they'll work for you.
Here's how to remove it (I wrote these directions based upon BBY pc app v3.5.1.2 from Jan 23, 2012):
1. Open Add/Remove Programs (Programs and Features on Vista/7), and remove pc app as you would normally. You may also want to uninstall any software downloaded through PC app.
2. Press Win+R to open Run. Type regedit and click OK. (Editing the registry incorrectly can crash your PC and require you to reinstall Windows. Follow these steps carefully).
3. On the left side, click the + next to the HKEY_LOCAL_MACHINE registry key to open it. Then repeat to open SOFTWARE, Microsoft, Windows, CurrentVersion, and finally Uninstall.
4. Click on the first folder listed under Uninstall on the left. Look on the right side for the entry named DisplayName, and check to see if the Data is Best Buy PC App. If it is not, select the next folder under Uninstall. Continue to work down the list until you find a folder that has a DisplayName of Best Buy PC App, or until you reach the end of the list.
If you reach the end of the list without finding an entry for best buy pc app, skip to step 8.
5. Write down the name of the folder that contains the Displayname of best buy pc app (the folder name will look something like {FBBC4667-2521-4E78-B1BD-8706F774549B}, numbers and letters might be different ). Close the Registry Editor.
6. Press Win+R, then type the following: msiexec /i<name> SRCDIR=C:\windows\installer (replace <name> with the folder name you wrote down in step 5.) Note that there is NO SPACE between the /i and the <name>
An example that removes 3.5.1.2 is msiexec /i{FBBC4667-2521-4E78-B1BD-8706F774549B} SRCDIR=C:\windows\installer
7. An install wizard with no graphics should appear. If you receive an error or the installer for a different program opens, double check the name of the folder from step 4. Click Next, then click the blank square next to Remove. Confirm the removal.
8. Show hidden files if they are not already shown. To do this, open Control Panel, then select Folder Options. Select the View tab, then choose "Show Hidden Files and Folders" in the list. Click OK and close Control Panel.
Windows 7 users may not see Folder Options in control panel. If this is the case, click "Category" in the upper right corner, and select "Small Icons".
9.
Windows XP users: Press Win+R, then type %ALLUSERSPROFILE%\Application Data Click OK
Windows Vista/7 users: Press Win+R, then type C:\ProgramData Click OK
9. In the window that opens, look for a best buy pc app folder. If it exists, delete the entire folder.
10. Then, look for a folder whose name starts with a curly brace (" { " symbol). If one exists, open it. Verify that best buy pc app setup.exe is inside. If it is, delete the entire folder. Close the window.
11. Navigate to C:\Program Files in Windows explorer. If a best buy pc app folder exists, delete it. (Odds are good that this folder will not be there. The uninstall usually removes it).
12. Press Win+R again, this time type the following and click OK:
If you have Windows XP: %userprofile%\Application Data
If you have Windows Vista or 7: %userprofile%\AppData
13. In the window that opens, look for a best buy pc app folder. If it exists, delete the entire folder. Close the window.
12. Restart your computer.

Dear sir,
I have given the following coding as an assignment from my college.Please help me to solve it.I have to submit in few days. please reply me as soon as possible.
And assignment is:
h3. Problem Statement
You are trapped in a room full of zombies. Luckily the room is pitch black and, while the zombies can't see, you have night vision goggles. To get out though you will have to be careful, since bumping into a zombie is hazardous to your health.
More specifically, each zombie will have x and y coordinates between 0 and 99 inclusive. You start at (0,0). If you can get to (99,99), you can take an elevator to safety. You may not leave the room any other way. Get there as fast as you can!
You must implement a method move. This method takes two int[]s, zx and zy, giving the locations of all the zombies, along with ints x and y giving your location. Your method should return "S" to stand still, or "R", "L", "U", or "D" for the four cardinal directions, and "RU", "RD", "LU", or "LD" for the four diagonal directions: {noformat} LU U RU
L S R
LD D RD
{noformat}Moving right increases your x coordinate, while moving down increases your y coordinate.
After each of your moves, the zombies will all move randomly. Each zombie will chose a random direction (from the 9 including no move) and attempt to move in that direction. If a zombie wants to move outside of the box defined by (0,0)-(99,99) it will stay where it is instead. Note that while the initial locations of all the zombies are distinct, they will not stay that way -- multiple zombies may occupy the same location.
Each test case will be generated by first choosing a zombie density in [0.05,0.15]. All locations with x or y at least 5 will then contain one initial zombie with probability equal to the density.
The simulation will be run for a maximum of 10,000 time steps. You may run into zombies at most 10 times -- the 11th one will kill you. If you fail to reach the exit but you manage to stay alive for T time steps, your score will be T. If you make it to the exit at time T, your score will be 30000 - 2 * T plus 1000 per unused life. In other words, you have 10,000 steps to escape, and you get a bonus of 2 points for each time step you don't need to use. Your final score will simply be the average of your individual scores.
A simple is provided . To use it you need to write a program which communicates via standard IO. Your main method should first read in N, the number of zombies. For each call to move, you should read in N integers for zx, then N integers for zy, and finally two integers for x and y. You should simply output the move you would return. You can run it with something like: {noformat}java -jar Zombie.jar "java Zombie" -delay 1 -seed 1
{noformat}"java Zombie" is the executable, and should be replaced with whatever command will run your program. The -delay parameter sets the delay in milliseconds between moves. The -seed parameter specifies the random number generator seed (the examples are 1-10). There is also a -novis parameter which causes the simulation to be run with the visualization. Be careful not to output anything other than your moves to standard out. Standard error may be used for debugging purposes"

haytony, let me give you a word of advice. The more work you show, the more work the volunteers are often willing to give. For instance, if you've done a ton of research, wrote most of your own code but were stuck on specific points and posted this, the folks here will bend over backwards to lend you a strong hand to help you as much as possible.
If on the other hand, you simply post your entire assignment and don't show that you've done one speck of work, often we ignore you at best or ridicule you at worst.
C'mon, it's up to you. Step up to the plate and show us your work, and your worthiness for help. If you can prove yourself to be a hard-working studious type, then I personally will do all in my upmost to help you. If on the other hand you repeatedly spam these forums with pathetic attempts at getting others to do homework where there is absolutely no evidence that you have done a lick of work yourself, then I will ridicule, flame, and bother you to know end.
So which is it to be? Again, it's all up to you. Time to go to bat.
