Abstract: A computer implemented method of calculating and encoding depth data from captured image data is disclosed. In one operation, the computer implemented method captures two successive frames of image data through a single image capture device. In another operation, differences between a first frame of image data and a second frame of the image data are determined. In still another operation, a depth map is calculated when pixel data of the first frame of the image data is compared to pixel data of the second frame of the image data. In another operation, the depth map is encoded into a header of the first frame of image data.

Abstract: A system and method for performing manual partial transfers of image data includes a display controller with controller logic and a rectangle module. The rectangle module detects write operations to on-screen data in a video memory, and then updates a transfer rectangle to include written data from the foregoing write operations. The controller logic generates a transfer interrupt in response to a transfer trigger event in the display controller for initiating a manual partial transfer operation from the video memory to a display device. A central processing unit from a host electronic device detects the transfer interrupt and responsively coordinates the manual partial transfer operation to transfer rectangle data of the transfer rectangle from the video memory to the display device of the host electronic device.
