Abstract: An imaging method and apparatus which use a pixel array for capturing images and for measuring ambient light conditions.

Abstract: A method, apparatus and system are described providing a high dynamic range pixel. Operating conditions, including integration time and sensitivity of different photosensors, and signal processing, including gain settings, are selected to provide multiple possible response curves. An output is selected from the possible response curves and used to provide an overall pixel response curve to increase the pixel dynamic range.

Abstract: A method, apparatus, and system are disclosed providing an imaging device with memory cells containing anti-fuse elements located with or outside a pixel array. The memory cells are read out using control signal lines which are used to readout imaging pixels.

Abstract: Method, apparatus and systems are disclosed in which a digital imager has optically black reference pixels in at least one row of a pixel array. The signals from the reference pixels in one row of the array are used as reference signals to cancel out the row-wise noise from pixel signals readout from active pixels in other rows of the array. An arrangement for locating the array driving circuit relative to the reference pixels is also provided.
