A pixel data decompression method for decompressing a frame is provided. The method includes: loading memory storage addresses corresponding to to-be-decompressed blocks; reading and decompressing a pixel line of a current block according to a memory storage address of the current block; updating the memory storage address of the current block according to a decompression result; reading a memory storage address of a next block if decompression of a pixel line of the frame is not completed; and repeating the above steps until decompression of the frame is completed.

Pixel data compression and decompression method

A data compression system and a data compression method using the same are provided. The data compression method includes acquiring original data from a memory and performs image processing and quantization on the original data to transform the original data into a quantization matrix. The data compression method then transforms the quantization matrix into a digital sequence based on a coding table and compares the data volume of the digital sequence and a target volume to generate a volume difference. The data compression method transforms the digital sequence into an inverse quantization matrix based on the volume difference and then transforms the inverse quantization matrix into a modified digital sequence based on the volume difference. The data compression method repeats the processes until the data volume of the digital sequence is substantially equal to a target volume or within an acceptable range of the target volume.

A reference pixel memory storage space configuration method for configuring a main storage sub-space and an extra storage sub-space of a reference pixel memory storage space of a high resolution digital image capturing apparatus is disclosed. The method includes steps of: calculating a first frame to obtain a plurality of first reconstruction reference pixels; storing the first reconstruction reference pixels in the main storage sub-space; moving a search range window to search the first reconstruction reference pixels and calculating a second frame by referencing the first reconstruction reference pixels covered by the search range window to obtain a plurality of second reconstruction reference pixels, and when the search range window is moved from a first region to a second region in the main storage sub-space, the first region becomes an available space. The second reconstruction reference pixels are orderly stored in the extra storage sub-space and the available space.
