Abstract: Various embodiments provide an optimized image filter. The optimized image and video obtains an input image and selects a target pixel for modification. Difference values are then determined between the selected target pixel and each reference pixel of a search area. Subsequently, a weighting function is used to determine weight values for each of the reference pixels of the search area based on their respective difference value. The selected target pixel is then modified by the optimized image filter using the determined weight values. A new target pixel in an apply patch is then selected for modification. The new target pixel is modified using the previously determined weight values reassigned to a new set of reference pixels. The previously determined weight values are reassigned to the new set of reference pixels based on each of the new set of reference pixels' position relative to the new target pixel.

Abstract: An image sensor device may include an array of image sensing pixels with adjacent image sensing pixels being arranged in macropixel, and a processor coupled to the array of image sensing pixels. The processor may be configured to receive pixel signals from the array of image sensing pixels, and arrange the received pixel signals into macropixel signal sets for respective macropixels. The processor may be configured to perform, in parallel, an image enhancement operation on the received pixel signals for each macropixel signal set to generate enhanced macropixel signals, and transmit the enhanced macropixel signals.
