Abstract: Reducing consumption of image sensor processor bandwidth includes capturing an image containing subject matter with an image sensor and cropping the image to generate a cropped image. Cropping the image is performed by the image sensor in response to coordinates received from an image sensor processor. The cropped image is sent from the image sensor to the image sensor processor and new coordinates based on a position of the subject matter in the cropped image are determined with the image sensor processor. The new coordinates are then sent to the image sensor.

Abstract: A method determines a pixel value in a high dynamic range image from two images of different brightness by obtaining corresponding input pixel intensities from the two images, determining combination weights, and calculating the pixel value in the high dynamic range image as a weighted average of the input pixel intensities. Another method determines a pixel value in a high dynamic range image from more than two images by forming pairs of corresponding input pixel intensities, determining relative combination weights for the input pixels intensities for each pair, applying a normalization condition to determine absolute combination weights, and calculating the pixel value in the high dynamic range image as a weighted average of the input pixel intensities. Systems for generating high dynamic range image generation from two or more input images include a processor, a memory, a combination weight module, and a pixel value calculation module.
