Abstract
A first exemplary aspect of the present invention is an image processing device that executes image processing including first image processing and second image processing by using a pipeline mechanism, the image processing device including: a first processing unit that executes the first image processing on an input image data, generates history information recording specifics of processing executed in the first image processing, and outputs the history information to the first processing unit; and a second processing unit that executes the second image processing on the image data obtained in the first image processing according to the output history information.
Claims10
An image processing device that executes image processing including a first image processing and a second image processing by using a pipeline mechanism, the image processing device comprising:
- a first processing unit that executes the first image processing on an input image data, generates history information recording specifics of processing executed in the first image processing, and outputs the history information to the second first processing unit;
- and
- a second processing unit that executes the second image processing on the image data obtained in the first image processing according to the output history information, wherein
- the second image processing includes edge emphasis processing to emphasize an edge in the image data,
- the second processing unit emphasizes the edge by a strength determined based on the output history information,
- the history information includes information indicating a degree of increase a pixel value in the image data, and
- the second processing unit decreases a strength by which the edge is emphasized as the degree of increase of the pixel value becomes larger.
An image processing method to execute image processing including a first image processing and a second image processing by a pipeline scheme, the image processing method comprising:
- executing the first image processing on image data;
- generating and outputting history information recording specifics of processing in the first image processing;
- and
- executing the second image processing on the image data obtained in the first image processing according to the output history information, wherein
- the second image processing includes edge emphasis processing to emphasize an edge in the image data,
- the second image processing emphasizes the edge by a strength determined based on the output history information,
- the history information includes information indicating a degree of increase a pixel value in the image data, and
- the second image processing decreases a strength by which the edge is emphasized as the degree of increase of the pixel value becomes larger.
A non-transitory computer readable medium recording an image processing program that causes a processor to execute second image processing among first image processing and second image processing included in image processing executed by a pipeline scheme, the image processing program for causing the processor to execute the processing comprising:
- obtaining a history information recording specifics of processing executed on image data in the first image processing;
- and
- executing the second image processing on the image data executed in first image processing according to the obtained history information, wherein
- the second image processing includes edge emphasis processing to emphasize an edge in the image data,
- the second image processing emphasizes the edge by a strength determined based on the output history information,
- the history information includes information indicating a degree of increase a pixel value in the image data, and
- the second image processing decreases a strength by which the edge is emphasized as the degree of increase of the pixel value becomes larger.
