Abstract

PURPOSE:To well adjust contrast, intensity, average intensity, by performing signal processing e.g., gamma control, for the image signal after its level adjusting with contrast. CONSTITUTION:The second electron 2 which is generated at the test material is sensed by the sensor 3. That sensing signal is used as an intensity varing signal of the cathode-ray tube 6 via the contrast-level adjusting circuit 4 and picture adjusting circuit 5. The picture adjusting circuit 5 consists, for example, of switching step 7 and many correcting curve amplifying circuits 8-13, etc.
