1. A video image processing system comprising:
- a plurality of data input ports and at least one data output port;
a plurality of frame stores each capable of storing data equivalent to a frame of video information;
a common input highway for the frame stores and adapted to receive data for storage in the frame stores;
a common output highway for the frame stores and adapted to provide data from the frame stores to the at least one output port;
processing means adapted to have access to at least one of the common input and output highways respectively to effect processing of the data available therefrom;
control means for controlling the passage of the data to and from the common highways to allow the processing means, the data input ports, and the at least one data output port to independently gain access to the frame stores for given time slots on a time multiplex basis; and
data buffer means for assembling received data into blocks and connected to receive data from respective data input ports and from said processing means, and to pass received data in blocks to the input highway during respective time slots.

Abstract
A video processing system including a number of frame stores with common highways. A number of input ports together with a computer have access to the input highway via buffers and the output ports together with the computer have access to the output highway via buffers. Each port together with the computer is allocated sequential time slots of short duration by a time slot control. Thus to an operator it will seem that he has continuous access to the system. Image planes greater than normal frame size can be handled by the address control. Additional data paths and processing hardware may be provided to enhance the system capabilities.

30. A video image processing system comprising:
-
a plurality of frame stores each capable of storing data equivalent to a frame of video information; means for applying video data to said frame stores so that data information relating to different image frames are stored in different ones of said frame stores; means for selectively reading data from said frame stores to derive signals from a group of said frame stores, which derived signals constitute a desired output frame of video information; said means for selectively reading including presettable means for selecting data from storage positions in said group of frame stores determined by the setting of said presettable means and so related that said desired output frame is built up of video information relating to adjacent areas of the different frames stored in said group of frame stores. - View Dependent Claims (31, 32)

33. A video image processing system comprising:
-
a plurality of frame stores each capable of storing data equivalent to a frame of video information; a video processor, for processing data so as to modify said video information; means for applying processed data from said video processor to a selected one of said frame stores; means for applying input data to said video processor; means for selectively reading data from said frame stores to derive data representing output video information; a data path; and means for connecting said data path from the output of another selected one of said frame stores to the input of the video processor, to include said video processor in a recursive video processing loop. - View Dependent Claims (34, 35, 36)
