Abstract
An image processing system comprises a plurality of memories to which image data is input, a control circuit for selecting areas for image processing from the image data input to the memories, and a plurality of DSPs connected to the memories and performing image processing of the selected image data selected by the control circuit. The present invention provides a an image processing system and method where selected image data including overlap areas can be sent from memories to DSPs by entering the same image data into a plurality of memories, without requiring transfers of overlap areas between DSPs, such that the image processing speed is improved.
Claims17
An image processing method comprising the steps of:
- inputting identical image data into a plurality of memories;
- selecting areas for image processing from said input image data;
- and
- performing image processing of each of the selected image data individually in the areas selected in said selection step with individual processors for each selected image data, and wherein said selection step further comprises a step of arranging said areas so as to vary with each image data input to said plurality of memories.
An image processing system, comprising:
- a plurality of memories to which identical image data is input;
- a control circuit for selecting areas for image processing from the image data input to said memories;
- a plurality of processors connected to said memories, each for image processing of selected image data in areas selected by said control circuit.
An image processing system, comprising:
- at least two memories to which identical image data is input;
- a control circuit operable with at least one of said at least two memories for selecting areas for image processing from the image data input to said memories;
- a plurality of processors connected to said memories individually for image processing of varied image data selected from said image data in areas selected by said control circuit, wherein said varied image data varies with each of said at least two memories;
- wherein at least one overlapping area exists between two portions of said selected image data.
