Abstract: Multiple read image sensors, and associated methods for the same, are disclosed herein. In one embodiment, a method comprises reading out a reset level from a pixel to a corresponding sample and hold circuit; storing the reset level to a first storage device and to a second storage device of the sample and hold circuit; reading out a signal level from the pixel to the sample and hold circuit; and storing the signal level to a third storage device and to a fourth storage device of the sample and hold circuit. The reset level and the signal level can correspond to a same correlated double sampling of an image data signal captured by the pixel. The method can further include reading out the reset level from the first storage device; reading out the signal level from the third storage device; and recovering a first copy of the image data signal.

Abstract: A digital widescreen camera has an anamorphic lens focusing a field of view nearly twice as wide as tall on a photosensor array having nearly square aspect ratio. In embodiments, the photosensor array has an 8-pixel tiling unit organized as four pairs of adjacent left and right pixels, a first pair having two red-responsive pixels, a second pair having two blue-responsive pixels, and a third pair having two green-responsive pixels. In embodiments, signals from the 8-pixel tiling unit are processed into signals equivalent to signals from two adjacent Bayer-pattern 4-pixel tiling units. The corresponding method of digital photography includes receiving light through an anamorphic lens onto a photosensor array. In embodiments, the photosensor array has an eight-pixel tiling with four pairs of adjacent left and right pixels, a first pair with two red-responsive pixels, a second pair with two blue-responsive pixels, and a third pair with two green-responsive pixels.

Abstract: A display system includes a processor coupled to receive image data from an image source and a frame timing circuit. The processor is coupled to output the image data and first sync signals, where each one of the first sync signals is output after M number of pixel values of the image data are output from the processor. The frame timing circuit is coupled to the processor to receive the image data and the first sync signals. The frame timing circuit is coupled to output X number of pixel values of the image data and second sync signals to a display, where the X number of pixel values is an integer multiple of the M number of pixel values of the image data. Each one of the second sync signals is output after X number of pixel values of the image data are output from the frame timing circuit.
