Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
An image logic operation device for performing logic operations on images, comprising: a first microchannel spatial light modulator, including a first voltage-controlled electro-optic crystal, for storing a first light image and sending out said first light image by a first reading-out light, wherein the first light image is reversed when a voltage is applied to said first voltage-controlled electro-optic crystal; a second microchannel spatial light modulator, including a second voltage-controlled electro-optic crystal, for storing a second light image and sending out said second light image by a second reading-out light, wherein the second light image is reversed when a voltage is applied to said second voltage-controlled electro-optic crystal; and an analyzer for passing therethrough said first light image, wherein the output of the analyzer is provided as said second reading-out light to said second microchannel spatial light modulator, thereby performing an AND operation on said first and second light images.
Claim 2
Dependent Claim
150 words
