PURPOSE:To properly process each picture signal by making it have appropriate amplifying characteristics according to the types of test material and of signal sensing route. CONSTITUTION:The input signal is recorded in one input termination of image amplifying circuit 2 via the delay circuit 1. The amplifying degree of the image amplifying circuit 2 is defined by the amplifying control circuit 3. The output signal from the central control circuit 4 which has a memory function is used as the control signal for amplifying control circuit 3. Both the output of the A-D converting circuit 5, which converts an input image signal into an address signal corresponding to its signal level value, and the output of the mode selecting circuit 6, which generates a signal for selecting amplifying characteristics, are added. In the memorizing means, a multiplication degree control signal is memorized in every address which is assigned by two input signals. |
