Abstract

PURPOSE: To make image pickup signal level optimum and to simplify processing of position-detecting signal, by appropriately controlling a semiconductor chip lighting intensity or scanning speed of an image pickup device which scanningly detects image of the chip.
CONSTITUTION: An image signal of a semiconductor chip 1 from an image pickup device 4 is put into a calculator 7 through an AC-DC converter 6 and accumulated in a memory 8. And, the calculator 7 seeks an average value of detection level from picture element level and feeds this back to an image pickup control device 5. The image pickup control device 5 optimizes image pickup signal by controlling image pickup scanning speed in the image pickup device 4 on the basis of the feedback information or by energizing a light source driving device 9 to set lighting intensity of a light source 3 variably, etc.
