Abstract
In a pipeline process operation including a branching process unit 25 as one of process modules, this branching process unit 25 is provided with an input management unit 251 for managing an input condition, a branching information management unit 252 for managing information as to branching destinations, a buffer unit 253 whose upper storage limit can be designated, and a branching control unit 254 for controlling an entire branching process unit. The branching process unit 25 may execute an arbitrary number of branching process operations without having such a buffer for an entire image.
Claims11
An image processing apparatus comprising:
- image storage device for storing digital image data;
- image input device having a function capable of sequentially reading required image data from at least said image storage device;
- branching process device capable of outputting entered image data to a plurality of output destinations;
- a process storage unit including said image input device, another image processing device, and said branching process device;
- and
- a plurality of image processing devices having a function capable of acquiring a data portion necessary for the image processing operation from at least said image input device, another image processing device, or said branching process device, and for executing a predetermined process operation as to said acquired data portion, wherein
- said branching process device includes:
- input management device for managing input conditions from at least said image input device, or from said image processing device;
- branching information management device for managing information of branching destinations;
- buffer device of which upper capacity limit is capable to be designated;
- and
- branching control device for controlling an entire branching process operation.
An image processing apparatus comprising:
- image storage device for storing digital image data;
- image input device having both a function capable of sequentially reading image data requested from at least said image storage device, and another function capable of re-executing the reading operation of the image data from a head of an image;
- branching process device capable of outputting entered image data to a plurality of output destinations;
- a process storage unit including said image input device, another image processing device, and said branching process device;
- and
- a plurality of image processing devices having both a function capable of acquiring a data portion necessary for the image processing operation from at least said image input device, another image processing device, or said branching process device, and for executing a predetermined process operation as to said acquired data portion, and another function capable of initializing a condition in such a manner that said predetermined process operation is re-executed from the head of the image, wherein
- said branching process device includes:
- input management device for managing input conditions from at least said image input device, or from said image processing device;
- and
- branching information management device for managing information of branch destinations.
A pipeline process for an image processing, which is performed by
- plurality of process modules including an image inputting process module for inputting process-purposed image data, and
- a branching process module capable of outputting the inputted image data to a plurality of output destinations,
- said plurality of process modules and said branching process module being connected to each other in a pipeline mode,
- said pipeline process comprising the steps of:
- re-executing a process operation from a head of the process-purposed image data by each of said plural process modules, and
- managing at least an arbitrary number of branching destinations by said branching process module.
