Abstract:
An image filming and compression system, comprising:a filter member including a plurality of color filters arranged in a predetermined arrangement;a solid state image sensor, including a plurality of pixels corresponding to the plurality of color filters, for filming an object via the filter member and outputting an electric signal from the plurality of pixels as image data according to an amount of light received;a block forming circuit for dividing all the image data outputted by the solid state image sensor into blocks corresponding to the plurality of pixels according to the arrangement of the plurality of color filters constituting the filter member; andan image data converter for calculating spatial frequency components of a luminance signal and a color difference signal for each block according to the image data obtained from the block forming circuit, wherein the image data converter calculates the spatial frequency components of the luminance signal and the color difference signal by conducting only linear transformation on the image data in each block.
