ABSTRACT:
A digital electronic camera apparatus which features an image pickup for picking up an image optically and converting the picked up optical image to an analog signal. An analog/digital converter converts the analog signal to a digital signal, and a digital processor converts the digital signal to a luminance signal and color difference signals. A first memory stores a frame of the luminance signal and the color difference signals, or a frame of the digital signal output from the analog/digital converter. A second memory stores n, where n is an integer, lines of the luminance signal and the color difference signals. A third memory stores a block n.times.n signal from the luminance signal and the color difference signals which are in the line memory, or which are output from the digital processor means. A compressing circuit compresses the signal from the third memory. A recording device records the signal from the compressing circuit in a recording media. In accordance with the present invention, a digital electronic camera apparatus which compresses a video signal and records a greater amount of the video signal in a recording media in case of motion video and still video can be achieved.
