A method, apparatus, and system that provides a holographic layer as a micro-lens array and/or a color filter array in an imager. The method of writing the holographic layer results in overlapping areas in the hologram for corresponding adjacent pixels in the imager which increases collection of light at the pixels, thereby increasing quantum efficiency.

Method of forming an imaging device

Methods, systems and apparatuses for the detection of motion using statistics data already available within an imager, such as sharpness scores or brightness values. The method includes obtaining at least two sets of statistics data for respective image frames which include corresponding windows; initializing a motion counter; determining, for each window, a relative difference value for the particular window; comparing the relative difference value to a first threshold. If the relative difference value is greater than the first threshold, the method increments the motion counter; and determines if there is motion by comparing the value of the motion counter to a second threshold. The motion detection may further take into account the relative importance of certain areas of the image frame.

Methods, systems and apparatuses for motion detection using auto-focus statistics

Surface generation and positional gain adjustment techniques for an imager are described. Embodiments of the techniques use zones having flexible boundaries which can be reconfigured depending upon the type of lens being used in a given application. Each pixel within each zone is multiplied by a correction factor dependent upon the particular zone while the pixel is being read out from the array. The correction factors comprise coefficients that are different for each color channel and in some instances different for each corner of each color channel.
