PURPOSE:To achieve a recorded picture excellent in color reproduction, by controlling number of ink dots of each color delivered from each ink jet nozzle, through the reading method of recorded picture of a recorded paper. CONSTITUTION:Optical current is changed for photosensors 110-112 through the amount of reflected light of each color component of R, G, B on a color original 2, the output is changed into a voltage value and given to signal delay circuits 116- 118 and A/D conversion circuits 122-124. The signal is in A/D conversion with reference voltages VR1, VR2, VR3 and applied to a color correction circuit 125 for a prescribed operation. Color ink signals are outputted, and the signals energize the ink jet nozzles via drive circuits 126-128 to form a recorded picture on a recording paper. The amount of reflected light of this picture is adjusted with reference signal voltages 107-109 electrically at comparators 107-108 with the amount of reflected light on the original 2. Thus, the number of ink dots of each color delivered from the nozzles can be controlled. |
