Abstract: An integrated image-input type display unit employs a conventional liquid crystal display panel and is capable of optically writing an original image directly at a high resolution into liquid crystal display panel and electrically reading the image. This unit has an image input/output device comprising a liquid crystal cell which contains light-sensitive molecules. The light-sensitive molecules are capable of changing their structure to a first molecular structure when being irradiated with light of a first wavelength range and to a second molecular structure when being irradiated with light of a second wavelength range, and are further capable of changing their alignment in accordance with the structural change of the light-sensitive molecules.

Abstract: The shading correction is performed with respect to a signal "A" indicative of the image density read by an optical read device in accordance with a reference signal "B". Both the signals "A" and "B" consist of n bits. An inputted signal having an initial value "A" is doubled by a multiplier when A=B and B.noteq.0. A subtracter subtracts the reference signal "B" from a signal "X" outputted from the multiplier and discriminates whether or not a signal "X-B" is negative. An S/P conversion register doubles an integrated value "S" having an initial value "0" and changes the integrated value from "S" to "2S" when the signal "X-B" is negative. In contrast, when the signal "X-B" is not negative the S/P conversion register adds "1" to "2S" and changes the integrated value from "S" to "2S+1". The signal "X" outputted from the multiplier is again inputted into the multiplier when the signal "X-B" is negative.
