ABSTRACT:
An image signal processing method and system, which can greatly reduce the data size upon transmitting an image signal or storing the signal in a storage medium, and can obtain a high-quality image by preventing image quality after color processing from deteriorating. According to the method for processing an image signal output from an image sensing element, a compression step of compressing the image signal and an expansion step of expanding the compressed image signal are executed without executing color processing for executing at least white balance correction or correction, and the color processing is executed after completion of the compression and expansion steps, thereby preventing occurrence of block noise and high-frequency noise associated with compressing/expanding image data after the color processing of the image signal.
