Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise exposing a plurality of pixels on an image capture device to a modulated light signal reflected from different regions of a scene adjacent a camera after different delays. The method may also comprise correlating intensity of the modulated light signal received by the image capture device for each the different delays to determine a flight time of the modulated light signal. The method may also comprise generating a Z-buffer corresponding to the different regions of the scene based on the correlation.

Systems and methods of generating Z-buffers for an image capture device of a camera

Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise actuating a light sensor after various delays to receive a plurality of modulated light signals reflected from different regions of a scene adjacent a camera. The method may also include determining distance information for the different regions of the scene based on brightness values for the plurality of modulated light signals reflected from the scene for the various delays. The method may also include storing the distance information in a Z-buffer at the camera.

The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.

Digital imaging device shutter calibration method and apparatus using multiple exposures of a single field

A digital imaging device having a CCD sensor array with one or more fields captures both short and long exposures of a particular field during the capture of a single image frame. The short-exposure image data and the long-exposure image data from the particular field may be correlated to estimate motion within the image frame.
