I get a message that says, 'Your camera is currently unavailable. Ive tried to restart my computer and load the app from the web store as suggested but does work.

The application is continuously updated to include advanced features such as panoramic preset image mapping, Xbox joystick control, and keyboard shortcuts.вЂ” Wednesday, July 15th 2009 UVC Camera Control for Mac OS X. The PTZOptics camera control application controls pan, tilt, zoom cameras connected via IP and USB and provides maximum flexibility for video productions.

In fact, there's no way to change any parameters of your camera. I thought I could just turn the auto exposure off and set it to a fixed value through some QTKit API вЂ“ but no, there's no way to change the exposure of a UVC camera with QTKit. I was able to get to the raw camera images through the QTKit Framework in no time.However, the QuickCam 9000 has its auto exposure enabled by default, which is absolutely deadly for stable tracking results.

You can use the USB Prober to find the values of your camera. So exposure, gain, brightness, contrast, saturation, sharpness and white balance all accept values from 0.0 to 1.0.In this example, VendorID and ProductID are the ones of the Logitech QuickCam 9000. Before setting a value the UVCCameraControl class asks the device for the min and max value for that setting and maps the input value accordingly. You can use it like this: UVCCameraControl * cameraControl = InitWithVendorID : 0x046d productID : 0x0990 ] All the input values are normalized. After some more hours of playing around with the Kernel Framework's USB API, I was finally able to control some of the QuickCam's settings! UVCCameraControl classI've now cleaned up the source a bit and organized everything in a UVCCameraControl class.

I've also only implemented those controls that are supported by the QuickCam вЂ“ other cameras might not support all of these, or might support additional ones.Note that you only have access to the camera if it is not in use by another process. So all I know at this moment, is that it works with the QuickCam. However, I wasn't able to control the built-in iSight of my MacBook Air at all and I don't have any other cameras to test this with.

There's no system setting to select the default video device, however the device you selected to use in iChat will be the default (you have to quit iChat after selecting your camera, otherwise it will be locked for all other applications).The controls currently supported by the UVCCameraControl class are: - ( BOOL )setAutoExposure :( BOOL )enabled - ( BOOL )getAutoExposure - ( BOOL )setExposure :( float )value - ( float )getExposure - ( BOOL )setGain :( float )value - ( float )getGain - ( BOOL )setBrightness :( float )value - ( float )getBrightness - ( BOOL )setContrast :( float )value - ( float )getContrast - ( BOOL )setSaturation :( float )value - ( float )getSaturation - ( BOOL )setSharpness :( float )value - ( float )getSharpness - ( BOOL )setAutoWhiteBalance :( BOOL )enabled - ( BOOL )getAutoWhiteBalance - ( BOOL )setWhiteBalance :( float )value - ( float )getWhiteBalance Download This demo uses QTKit to open a connection to the first (default) video device and simply displays the images in a QTCaptureView. So if you're doing blob tracking or marker detection or any other computer vision stuff, this probably is what you're looking for.I also built a simple demo application that makes use of the UVCCameraControl class. The UVCCameraControl class is only useful for you, if you use the camera in your own application. My understanding is that if you'd want to do that, you'd have to write a Kernel Extension.

Do whatever you want with it.
