ABSTRACT:
An image signal processing apparatus, the method and a camera system are provided, by which highly efficient processing close to 1-path processing can be performed without deteriorating a picture quality or taking too much time for the processing, a capacity required for a compression rate, band and memory in the worst case can be assured and a random accessing property is not impaired when compressing image data: wherein the apparatus has at least a first signal processing unit, a second signal processing unit, and a storage unit accessed by the first signal processing unit and the second signal processing unit; wherein the first signal processing unit includes at its interface part with the storage unit a band compression expansion unit having functions of compressing input image data based on a predetermined band compression method, writing the same in the storage unit, and expands compressed data read from the storage unit.
