Problems solved by technology

However, from the viewpoint of the development period and cost of the image processing device, it is not beneficial to develop an image processing device having the necessary image processing function for each model deployed in the imaging device.
In addition, simply developing an image processing device having a plurality of image processing functions and commonly mounting it on all imaging devices becomes a factor that hinders price reduction in imaging devices equipped with fewer functions.

Abstract

Provided is an image processing device comprising an image processing unit in which a pipeline is configured by connecting in series a plurality of processing modules for performing predetermined processing on input data, and which performs pipeline processing as a result of sequential processing performed by the respective processing modules, the image processing unit being connected to a data bus, and image processing being performed on data that is read out via the data bus from a data storage unit connected to the data bus, wherein the image processing unit includes an input / output moduleincorporated in the pipeline as a processing module that performs different processing from processing performed by the respective processing modules, and the input / output module outputs, to an external processing unit outside the image processing unit directly and not via the data bus, processing data processed by a first processing module, which is positioned in a stage preceding the position where the input / output module is incorporated in the pipeline, and outputs externally processed data, which is obtained by external processing performed by the external processing unit on the processingdata and is input to the input / output module, to a second processing module directly and not via the data bus, the second processing module being positioned in a stage subsequent to the first processing module in the pipeline.

Description

technical field [0001] The present invention relates to an image processing device. Background technique [0002] In an imaging device such as a still image camera, a moving image camera, a medical endoscopic camera, or an industrial endoscopic camera, various image processing is performed by an image processing device such as a system LSI mounted thereon. In addition, various types of imaging devices have been developed according to the functions to be mounted, the processing capability (speed), and their prices. Therefore, it is desirable that the image processing device has an image processing function for realizing the functions mounted on the imaging device. However, from the viewpoint of the development period and cost of the image processing device, it is not advantageous to develop an image processing device having a necessary image processing function for each model deployed in the imaging device. Furthermore, simply developing an image processing device having a ...
