ABSTRACT:
An image logic operation device for performing logic operations on images, the device comprising a first image unit for storing a first light image and sending out the light image or the reverse thereof by a reading-out light, and a second image unit for storing a second light image and sending out the light image or the reverse thereof by a reading-out light. The reading-out light from the first image unit is passed through an analyzer and then used to read out the image from the second image unit, whereby AND operation on the images is thus performed. The image logic operation device according to this invention also performed other logic operations such as NAND, OR, NOR, XOR, XNOR and so on.
