Title: Picture processing system
Inventor: FUNAOKA CHIHIRO
IPC: H04N5/222
Filed: 1987-12-28
Abstract: PURPOSE:To attain high arithmetic processing speed by connecting each control ler, a picture memory and an arithmetic unit by two systems of image buses in a manner of enabling two-way propagation, providing a bus switch and applying repetitive calculation of an image data through the supply of a data signal to the image bus. CONSTITUTION:A system controller 5 is mounted only an input/output printed circuit board (A), and each part is controlled by the camera control signal outputted from the controller 5. For example, in the case of application of repetitive calculation with memories 8a, 8c, as shown in figure (a), a data read from the memory 8a enters an arithmetic unit 10 along the arrow shown in figure. After the data is subject to arithmetic processing in the unit 10 and the result is given to the memory 8c. In this case, the other memories 8b, 8d are bypassed. In the case of an example shown in figure (b), the data read from the memory 8c is processed conversely and stored in the memory 8a. The procedure above is repeated to attain repetitive high speed calculation.
