Abstract:
1. An image compression apparatus for processing color imaging signals outputted from a solid-state imaging device having a color filter having a predetermined color arrangement disposed on a light receiving surface thereof, said image compression apparatus comprising: a pre-processing means for effecting preprocessing to generate color imaging signals of locations spatially equivalent to the relative locations of pixels on said color filter from the color imaging signals outputted from said solid-state imaging device and to convert said color imaging signals into a predetermined arrangement format color by color with keeping color space of the color filter so as to generate image data groups; and an image compression means comprising a frequency converting section for treating an image data group arranged in said predetermined arrangement format as one unit to compute spatial frequency components within the one unit, a quantizing section for quantizing the spatial frequency components, and a coding section for coding the quantized spatial frequency components.
