摘要： PURPOSE:To improve the density level correction of an original by detecting maximum white/black density in forward operation in the movement toward sub scanning and controlling variably the offset and gain of a variable amplifier in the forward operation. CONSTITUTION:An original table 14 is moved in the direction 17 by a sub scanning motor 16. In this case the original table 14 is moved in a high speed and the maximum white density and the maximum black density of an original 13 are stored. In order to read an ordinary signal, the motor 16 moves the table 14 in the direction 18. In this case, the density level correction of an input signal is executed by the maximum white/black densities so as to control the density level range of an input original up to the maximum quantized power of an A/D conveter.

CONSTITUTION:A variation point of a picture signal is detected, and difference between the lengths of sections is decided so as to judge periodicity. Original characteristics are decided due to the periodical section length. This processor is constituted in such a way that due to the decision, the processing signal treated in accordance with the picture signal is switched and recorded. By the program written in a main memory 33, a CPU32 reads out picture signal data which are stored in a picture signal storage area of a magnetic disk device 34, and outputs the picture signal and a phase signal on a position detection means 9 of a picture signal variation point through an output channel 36. A picture signal variation point and an original characteristic code are outputted from an original characteristic giving means 17 in accordance with characteristics of the picture signal inputted to the detection means 9, read to the CPU32 through an input channel 35, and written to an original characteristic memory area of the magnetic disk device 34 as original characteristic data.
