Claims
- 1. An image analysis system comprising:
- an input terminal for accepting an image signal in analog form;
- an image input unit connected to said input terminal for analog-to-digital conversion for said image signal;
- a frame identification designator connected to said image input unit for supplying frame identification to each image frame at an output of said image input unit;
- a plurality of image processing units connected to said frame identification designator, each image processing unit having a capability to process an image frame which has a specific frame identification determined in each image processing unit, and said plurality of image processing units operating in one of three modes of operation consisting of a) concurrently processing the same image frame with different processing contents, b) sequentially inputting each of the input image frames and processing in a same manner and c) a mixture of concurrently and sequentially processing image frames; and
- a control means connected to said image processing units for controlling each image processing unit,
- each of said image processing units includes
- a frame identification selector for selecting said image frame selectively so that a specific image frame, having a frame identification equal to an identification determined in each image processing unit, is selected, and
- an image processing module for carrying out image analysis for said image frame selected by said frame identification selector.
- 2. An image analysis system according to claim 1, wherein each of said image processing units has a local control which controls operation of said frame identification selector and said image processing module in said image processing unit, and controls information transfer from and to said control means.
- 3. An image analysis system according to claim 1, wherein said frame identification selector includes has a number set, and coincidence means for comparing said frame identification of an input image frame with a number input by said number set, so that an image frame having the same frame identification as the number input by the number set is input into the image processing unit.
- 4. An image analysis system according to claim 1, wherein two way communication means is provided for transferring information between local controllers of image processing units.
- 5. An image analysis system according to claim 1, further comprising a processor network having a) a plurality of network processor groups coupled with one another, b) a first two way communication means coupling each network processor in said network processor groups with local controllers in said image processing units, and c) a second two way communication means coupling said processor network with said control means coupled with said image processing units.
- 6. An image analysis system according to claim 5, wherein each network processor group in said processor network for operating with a computer program which is supplied by said control means, and for exchanging processing results and parameters with other network processor groups within the processor network.
- 7. An image analysis system according to claim 5, wherein said processor network carries out image processing including image recognition.
- 8. An image analysis system according to claim 1, wherein each of said image processing units has a number set which specifies a mutually different number to identify each image processing unit, local controllers of each image processing unit calculates a second frame identification based on the number specified by said number set, and coincidence means for comparing said frame identification of an input image frame with said second frame identification calculated by said local controller, so that an image frame having the frame identification the same as the second frame identification calculated by said local controller is processed by the image processing unit.
- 9. An image analysis system according to claim 1, wherein said image analysis is a pixel level processing which is a basis for extracting a feature in said image frame.
- 10. An image analysis system comprising:
- an input terminal for accepting an image signal in analog form;
- an image input unit connected to said input terminal for analog-to-digital conversion for said image signal;
- a frame identification designator connected to said image input unit for supplying frame identification to each image frame at an output of said image input unit;
- a plurality of image processing units connected to said frame identification designator, each image processing unit having a capability to process an image frame which has a specific frame identification determined in each image processing unit, and said plurality of image processing units operating in one of three modes of operation consisting of a) each of the image processing units concurrently inputting the same image frame and each image processing unit processing the image frame differently from one another, b) each of the image processing units sequentially inputting a different one of input image frames and each image processing unit processing the input image frame in a same manner and c) the plurality of image processing units are grouped into a plurality of groups and image frames processed in each group are a mixture of concurrently and sequentially processed as described in a) and b); and
- a control means connected to said image processing units for controlling each image processing unit,
- each of said image processing units includes
- a frame identification selector for selecting said image frame selectively so that a specific image frame, having a frame identification equal to an identification determined in each image processing unit, is selected, and
- an image processing module for carrying out image analysis for said image frame selected by said frame identification selector.
