Image processing apparatus, image capturing apparatus, control method, and recording medium

An image capturing apparatus comprising:

• an image sensor which performs image capturing, and output a target image;
• a first processing circuit which performs first image processing for the target image output from the image sensor, and write a first image as a processing result in a storage device;
• a second processing circuit which reads out the first image written in the storage device, perform second image processing different from the first image processing for the first image, and output a second image as a processing result;
• and
• a control circuit which controls the first processing circuit and the second processing circuit,
• wherein the first image processing and the second image processing are performed for each of a plurality of regions defined for an image as a processing target,
• readout of the first image by the second processing circuit is performed in parallel with write of the first image by the first processing circuit, and
• the control circuit sets sizes of first regions and sizes of second regions based on a state of the image capturing apparatus when the image sensor captures the target image, and sets the size of the second region defined for the first image as a processing target of the second image processing to be smaller than the size of the first region defined for the target image as a processing target of the first image processing.

A control method for an image processing apparatus, comprising:

• performing first processing of performing first image processing for a target image as an input processing target, and writing a first image as a processing result in a storage device;
• performing second processing of reading out the first image written in the storage device, performing second image processing different from the first image processing for the first image, and outputting a second image as a processing result;
• and
• controlling performance of the first processing and the second processing,
• wherein the first image processing and the second image processing are performed for each of a plurality of regions defined for an image as a processing target,
• readout of the first image in the second processing is performed in parallel with write of the first image in the first processing, and
• performance of the first processing and the second processing is controlled so that a size of a second region defined for the first image as a processing target of the second image processing is smaller than a size of a first region defined for the target image as a processing target of the first image processing.

A computer-readable recording medium recording a program for causing a computer to perform a control method for an image processing apparatus, the method comprising:

• performing first processing of performing first image processing for a target image as an input processing target, and writing a first image as a processing result in a storage device;
• performing second processing of reading out the first image written in the storage device, performing second image processing different from the first image processing for the first image, and outputting a second image as a processing result;
• and
• controlling performance of the first processing and the second processing,
• wherein the first image processing and the second image processing are performed for each of a plurality of regions defined for an image as a processing target,
• readout of the first image in the second processing is performed in parallel with write of the first image in the first processing, and
• performance of the first processing and the second processing is controlled so that a size of a second region defined for the first image as a processing target of the second image processing is smaller than a size of a first region defined for the target image as a processing target of the first image processing.
