To provide an image processor capable of adjusting a relative position between an image pickup means and a light detection means while confirming the focusing state of the image pickup means.

The image processing means for processing an optical image obtained by the image pickup means (lens part 10) and detected by the light detection means (semiconductor image pickup part 20) is provided with a light detection means position changing mechanism (adjusting rod 40) arranged on a position separated from that of the light detection means so as to change the relative position of the light detection means to the image pickup means, an operation means (adjusting ring 50) for operating the position changing mechanism and an electric image display means (liquid crystal display 60) arranged near to the operation means and connected to the light detection means.
