IPC: H04N1/409
Filed: 1989-07-28
Abstract: PURPOSE:To obtain a picture processing device which can improve a blurred picture and obtain a clear picture by executing the prescribed processing of division, subtraction and multiplication after an original picture is smoothing-processed. CONSTITUTION:An original picture A obtained by photographing an eyeground by the CCD camera 2 of an eyeground camera 1 is digitized, and is stored in a picture memory 6, and when the picture is blurred when it is observed by a picture monitor 8, a selector switch 7 is switched, and at first, the picture A is read into a picture processor 4. Next, a smoothing filter F is set to all the picture elements of the picture A, and smoothing processing to substitute the mean value of all the picture element levels of a picture element area is executed, and the eyeground picture B is obtained. Next, the eyeground picture C is obtained by dividing each picture element level of the picture B by a constant (a) larger than '1', and the eyeground picture D is calculated by subtracting the corresponding element level of the picture C from each picture element level of the picture A in the memory 6. Next, each picture element level of the picture D is multiplied by a/(a-1), and the eyeground picture E is obtained. When the picture E is monitored, the clear picture E with less blur can be observed.

Title: Optical demultiplexer/multiplexer and light transmission system
Inventor: HAYATA HIRONORI
IPC: G02B6/293
Filed: 1989-07-31
Abstract: PURPOSE:To increase the degree of multiplexing and to improve reliability by arranging optical fiber bundles to a hexagonally close packed state and directly mounting a filter and mirror to the other end of a lens. CONSTITUTION:This system is so constituted that the optical fiber bundles are arranged to the hexagonally close packed state and the fiber 11 and the mirror 13 are directly mounted to the other end of the lens 10. The distance to the optical fiber from the lens axis is, therefore, shortened and the influence of aberrations is decreased. Since the space does not exist on the optical path, the need for worrying about an increase of crosstalks by scattering, etc., and an increase of loss by dust and frost setting is eliminated; further, easy assembly is assured as there are no moving parts. The degree of multiplexing is increased in this way and the reliability is improved. The system having high reliability can be constructed if 2X2 optical switches 26 are used in combination.
