Program, image processing method, and image processing device

A non-transitory computer readable medium that stores a program causing a computer to perform an image processing method comprising:

• dividing input image data into a plurality of pieces of division image data including first division image data and second division image data having a predetermined overlap region with the first division image data according to a size of a kernel used for image processing;
• determining first reuse data to be reused in performing the image processing to the second division image data among the first division image data;
• and
• in a memory, storing first processed data of a first division image, which is obtained by performing the image processing to the first division image data, in a region other than a region storing the first reuse data, and allocating a region storing the second division image data so as to be adjacent to the region storing the first reuse data,
• wherein the input image data comprises first image data and second image data, and
• wherein the image processing method further comprises:
• dividing second image data in a plurality of pieces of division image data including third division image data and fourth division image data having a predetermined overlap region with the third division image data according to a size of a kernel used for image processing;
• determining third reuse data to be reused in performing the image data to the fourth division image data among the third division image data;
• in the memory, storing first proceeded data of a third division image, which is obtained by performing the image processing to the third division image data, in a region other than a region storing the third reuse data, and allocating a region storing the fourth division image data so as to be adjacent to the region storing the third reuse data;
• storing, in a wraparound method, the first division image data, data obtained by performing the image processing to the first division image data, the second division image data, and data obtained by performing the image processing to the second division image data in a first wraparound range of the memory;
• and
• storing, in the wraparound method, the third division image data, data obtained by performing the image processing to the third division image data, the fourth division image data, and data obtained by performing the image processing to the fourth division image data in a second wraparound range different from the first wraparound range of the memory.

An image processing device comprising:

• a processor;
• and
• a memory storing a program that, when executed by the processor, causes the processor to:
• divide input image data into a plurality of pieces of division image data including first division image data and second division image data having a predetermined overlap region with the first division image data according to a size of a kernel used for image processing;
• determine first reuse data to be reused in performing the image processing to the second division image data, among the first division image data;
• and
• store, in the memory, first processed data of a first division image, which is obtained by performing the image processing to the first division image data, in a region other than a region storing the first reuse data, and allocate a region storing the second division image data so as to be adjacent to the region storing the first reuse data,
• wherein the input image data comprises first image data,
• wherein the processor is configured to divide second image data into a plurality of pieces of division image data including third division image data and fourth division image data having a predetermined overlap region with the third division image data according to a size of a kernel used for image processing,
• wherein the processor is configured to determine the first reuse data to be reused in performing the image processing to the fourth division image data among the third division image data,
• wherein the processor is configured to, in the memory, store first processed data of a third division image, which is obtained by performing the image processing to the third division image data, in a region other than a region storing third reuse data, and to allocate a region storing the fourth division image data so as to be adjacent to the region storing the third reuse data, and
• wherein the processor is configured to:
• store, in a wraparound method, the first division image data, data obtained by performing the image processing to the first division image data, the second division image data, and data obtained by performing the image processing to the second division image data in a first wraparound range of the memory;
• and
• store, in the wraparound method, the third division image data, data obtained by performing the image processing to the third division image data, the fourth division image data, and data obtained by performing the image processing to the fourth division image data in a second wraparound range different from the first wraparound range of the memory.
