a first switching means for determining the upper 2 bit data out of the digitalized 10 bit data from a CCD and selecting one of a γ compensator and Knee compensator; a γ compensator for γ correcting the lower 8 bit data out of the received 10 bit data by means of a memory element; a first Knee compensator for generating the lower 9 bit data out of the received 10 bit data in an approximate straight line; a second Knee compensator for generating the lower 8 bit data out of the received 10 bit data in an approximate straight line; and a second switching means for determining the upper 1 bit data out of the received 10 bit data and selecting one of the first and the second Knee compensators. so as to input the data into the first switching means.
