摘要： A method of compressing an image according to an image compression algorithm includes sequentially receiving pixel values into a buffers bank in line-by-line order. The image includes a plurality of pixels arranged into lines and columns. Each pixel has a pixel value associated therewith. Each line has L pixels. The image compression algorithm operates on blocks of pixels, each block having N lines and M columns. The method also includes storing each block-line of pixel values in a buffer of the buffers bank. A block-line includes M consecutive pixels of a line. The method also includes, for each block-line, storing a pointer to the buffer in which the block-line is stored and reading block-lines out of the buffers bank to a compression engine, wherein the block-lines are read out of the buffers bank in an order that is different from the line-by-line order in which the block-lines were received into the buffers bank. The method further includes compressing the image according to the image compression algorithm and displaying the image.

摘要： A method of operating an image sensor apparatus is provided. In this method, first digital image data is generated based on a first exposure data signal, wherein the first exposure data signal is indicative of an exposure level of the image sensor during a first exposure period. The first digital image data is stored in a storage circuit. Second digital image data is generated based on a second exposure data signal, wherein the second exposure data signal is indicative of an exposure level of the image sensor during a second exposure period. The second exposure period is different from the first exposure period. The second digital image data associated with the image sensor is selectively stored based on a value of the first digital image data associated with the image sensor.
