Abstract:
A digital still camera that compresses a video signal acquired by photographing an object with a CCD imaging device, stores it in a storage element, reads said compressed video signal from the storage element and reproduces said video signal, comprising:expansion processing means for performing expansion processing on said compressed video signal and outputting said video signal in units of block as luminance data and color difference data respectively having a first data length; a frame memory having a second data length equivalent to the double of said first data length; video data block generating means for generating a block of video data having said second data length by connecting the luminance data and the color difference data respectively having said first data length and output from said expansion processing means, in units of block; and writing means for writing a signal output from said video data block generating means to said frame memory in units of block of said video data, wherein said video data block generating means is provided with selectors for respectively selecting said luminance data and said color difference data, and connecting means for connecting the selected luminance data and color difference data.
