<p>In an electronic endoscope, when an error judgment circuit judges a pixel has an error, it outputs an error judgment signal and temporarily acquires images of a synchronization memory F, a synchronization memory G, and a synchronization memory R in a memory. Simultaneously with this, the error judgment circuit controls an error position display circuit (52). The error position display circuit superimposes/displays a mark indicating the position where the error pixel exists on the image acquired temporarily in the memory and outputs still image data on the normal image stored in the temporary memory superimposed by the mark to a D/A conversion circuit, thereby causing a monitor to perform thumbnail display. Thus, it is possible to easily and surely identify an area which is suspected to be an abnormal tissue by an ordinary color endoscope image.</p> |
