Abstract
In a digital image recording/reproducing apparatus of the invention, image data obtained via a charge-coupled-device (CCD) is processed by a processing circuit so as to produce a luminance signal and color-difference signals, which are supplied to corresponding first frame memories via selectors and temporarily stored therein. Then the data are read from the first frame memory and subjected to data conversion in terms of vertical pixels via line memories and further via vertical pixel conversion circuits. The data is then subjected to data conversion in terms of horizontal pixels via a first horizontal pixel conversion circuit. The resultant data is selectively supplied to a monitor and an electronic viewfinder via a selector or stored in a second frame memory. The data stored in the second frame memory is read via a selector and subjected to data compression. The resultant data is then recorded on a recording medium.
