Abstract
An electronic endoscopic apparatus having various sorts of electronic endoscopes mounting a CCD with a different number of pixels, for example, 410,000 pixels, 270,000 pixels or 190,000 pixels that are connectable to a processor. A CCD drive and signal processing circuit drives all the CCDs at a frequency set up for the CCD with 410,000 pixels, and an information quantity conversion circuit expands an image acquired by the CCD with 270,000 pixels or 190,000 pixels by pixel interpolation in a horizontal direction or a vertical direction to form an image with an aspect ratio of 4 to 3. Also, a video signal acquired in an NTSC system is converted into a video signal of a PAL system by using a television standard conversion circuit, thereby displaying an excellent PAL video without any bar noise.
