1. An image processing method comprising:
- a generating step for generating image data by using a sensor which has a plurality of picture cells and color filters which are arranged as a predetermined array;
a separating step for separating the image data generated in said generating step into a plurality of image components, each of the plurality of image components corresponding to each of said color filters;
a setting step for setting quantization parameters suitable for obtaining an objective coding amount, in accordance with a predetermined image component separated in said separating step;
a first coding step for coding the predetermined image component in accordance with the quantization parameters set in said setting step; and
a second coding step for coding another image component separated in said separating step in accordance with the quantization parameters set in said setting step.

Abstract
An image processing system in which image data is generated in an offset sampled structure using a two-dimensional sensor. The generated image data is separated into a plurality of sets of image data having a lattice arrangement, and each of which has the same color. One set of the image data is coded in accordance with a first coding parameter, and another set of the image data is coded in accordance with a second coding parameter. The two sets of coded data are then stored in a memory for subsequent transfer to an image output device.
