Abstract

PURPOSE: To enhance the throughout for the picture process system, by installing an exclusive hardware having a function to secure a histogram in parallel to an input process at the input part of the picture data and then reducing the time required for production of an apparent histogram through a process.
CONSTITUTION: A received picture is reproduced by putting the reproduction command into the high-density magnetic tape 6 by a command of the CPU11 and via the high-density magnetic tape control device 12. At the same time, the received picture is read into the buffer memory 14 via the histograming device 13 and the input/output bus line 15 to be stored in a large-capacity memory device 9 by means of an interchange buffer means or the like. This action is carried out consecutively until a stop command is given to the tape 6 from the CPU11. Then the counter groups corresponding to the plural picture elements of the interception signal are actuated at the device 13 to integrate the picture data. The value of integration is used when a compensation is given to the picture to carry out a compensation of picture. Thus the time required for production of a histogram can be deleted.
