My iPhone application uses the camera to take pictures, which I suspect is somewhat memory-intensive. The app uses a custom background image for the view of its UINavigationController, and after taking a few pictures, the background goes all white. Any ideas on what I can do to stop this? ...
Hopefully easy answer, but I cannot get it. I have a 3D render engine I have written. I have the camera position, the lookat position and the up vector. I want to be able to "tilt" the camera left, right, up and down. Like a camera on a fixed tripod that you can grab the handle and tilt it it up, down, left right etc. The maths stum...
I've noticed that in OS 3.1 you can add an overlay view to the image picker with cameraOverlayView However, I've also noticed that adding a view via this method also displays the view for the entire time the UIImagePicker is displayed, when I only want to show it during the preview stage. Is there a way to make this only happen duri...

Hi there, I have the following problem: I implement an application that uses DirectShow to capture video and audio data.

On iPhone's built-in Camera application (OS 3.1), touching the shutter button shows an iris animation, then displays the image that was taken for a second or so before animating it away. Is anyone aware of a simple way to get this "brief pause" activity? Or do I have to resort to manually adding the image as part of my custom cameraOve...
We are utilizing the Intent.ACTION_IMAGE_CAPTURE for taking a new picture from within our app. However, we would like to force geo-tagging of the pictures. Is there a way to set the intent to do this or does it rely solely on the default Camera app's setting to "Store Location"? (Also, it would be nice if this worked for the ACTION_VIDE...

So I am working on an app that uses core data to store attributes of objects that the user can set. I have primarily been focusing on the first part, which was setting everything up on the core data side, and now I am ready to move on to the next part which deals with the camera. I want to be able to add a city, or other geographical loc...

I have an odd problem with UIImagePickerControllerSourceTypeCamera. My application gives the choice to select a pic from the gallery, or take a photo with the camera.

The Android SDK has an API demo for using the preview of the camera. However, this gives me a runtime exception in the emulator. I'm running with Eclipse on a Mac with 10.6 Here's the link where I grabbed the code: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html ...
This is a very beginner problem. I'm trying to display an image taken with the camera, but when I display the image in a UIImageView the image is blown up. For instance, if I take a picture of a persons face, when I display the image, it will be blown up so much that it's pixelated and all I see is a portion of a nose (or whatever). What...
I am looking for information on camera RS232/RS485 protocols. The camera I have lists its supported protocols as: Pelco D Pelco P Fastrax Command I don't think that Pelco has the features I need but I can't find any information on the last two. Pelco only appears to allow differential changing of zoom and focus (commands to move in/o...
