PURPOSE:To simplifying the constitution of an optical information processor which operates optical input information through an optical filter and generates output information, and improve the operability by using the optical fiber whose patterns are freely changeable. CONSTITUTION:Irradiation luminous flux from a laser 51 is transmitted through an image 61 to be inspected to obtain optical input information, which is processed through the filter 63 of an optical controller and photodetected by a photoelectric converting element 65 in the form projection light of output information. This filter 63 has patterns changed freely by the movement of a grain body in a liquid layer on the basis of feeding to a specific heating resistance body by a heating resistance body driving circuit 71 which reacts to a filter pattern generating circuit 70. Therefore, an optical filter having many kinds of patterns need not be prepared, the constitution of the optical information processor is simplified, and the operability is improved.
