ABSTRACT:
An image filming and compression system includes a color complementary filter having a predetermined color arrangement; a CCD for generating image data for output according to the light of an object received via the color complementary filter; block forming circuit for dividing the image data into blocks; and image data converter circuit for calculating spatial frequency components of a luminance signal and color difference signals for each block according to the image data. The image data converter circuit directly calculates the spatial frequency components of the luminance signal and the color difference signals by conducting the only linear transformation on the image data. This obviates the need for a means to generate the luminance signal and the color difference signals according to which the spatial frequency components of the luminance signal and the color difference signals are calculated. Consequently, it becomes possible to conduct the processes from the image filming of the object to the compression of the image data with high efficacy, and hence to reduce the size of the system.
