Abstract
PURPOSE: To reduce the deterioration of light, to improve S/N ratio and to identify the code on document, by picking up the code on document with two sheets of long wave transmission filters as three color signals of red, yellow and white and operating among the three color signals.
CONSTITUTION: The code on the document 1 is picked up with the photo electric conversion elements 10, 20 provided respectively with the red transmission filter 11, yellow transmission filter 21 and the photo electric conversion element 30 without filter, the red information only is picked up with the element 10, and the element 20 reads in the information synthesizing red and green among three original color. Further, the element 30 reads in the these original color synthesized information, the electric signal read in is fed to the video amplifiers 12, 22, 32, the signals R, R+G and R+G+B outputted from the amplifiers 12, 22, 23 respectively are fed to the differential amplifiers 23, 33, for mutual operation to obtain the outputs R, G, B corresponding to the three original colors, and identification of the code on the document 1 is made with less deteriorated light amount.
