Abstract
A CCD image pickup device 21 has all-pixel read mode and a double speed read mode. The number of lines in the vertical direction is 1/2 of that of the all-pixel read mode. In the double speed read mode, the number of pixels in the horizontal direction is halved by a VRAM write controller 33. A VRAM 34 stores a picture of which pixels have been 1/4 thinned out. The stored picture is output to a monitor 4. The monitor 4 displays a live picture on real time basis. In the all-pixel read mode, a picture is stored in a frame memory 40. The memory picture is 1/4 thinned out. The resultant picture is output as a preview picture to the monitor 4 through the VRAM 34. Background picture data is stored in a background picture memory 44 through a SPC 42. The mix circuit 45 composites the background picture received from the background picture memory 44 and the picture received from the VRAM 34 and outputs the composite picture to the monitor 4.
