Image processing apparatus, projection display apparatus, video display system, image processing method, and computer readable storage medium

An image processing method which processes image data corresponding to a display image and processes at least image data corresponding to an image having a reference resolution P which is a resolution as a reference, the resolution representing the number of constituent pixels, the image processing method comprising:

• when image data corresponding to the input display image is the image having the reference resolution P, segmenting image data into image data corresponding to M (where M is an integer equal to or greater than 2) partial images having a resolution R and processing segmented image data in parallel;
• when image data corresponding to the input display image has a resolution Q lower than the reference resolution P, and one of N (where N is an integer equal to or smaller than M−1) segmented partial images has a resolution equal to or lower than a resolution R, segmenting image data into L (where L is an integer equal to or greater than N+1 and equal to or smaller than M) pieces of image data and processing image data corresponding to the partial images in parallel;
• and
• reconstructing the display image on the basis of processed image data corresponding to the M or L partial images.

A computer readable storage medium storing a computer program which causes a computer to realize an image processing function of processing image data corresponding to a display image and processing at least image data corresponding to an image having a reference resolution P which is a resolution as a reference, the resolution representing the number of constituent pixels, the computer program causing the computer to execute:

• when image data corresponding to the input display image is the image having the reference resolution P, segmenting image data into image data corresponding to M (where M is an integer equal to or greater than 2) partial images having a resolution R and processing segmented image data in parallel;
• when image data corresponding to the input display image has a resolution Q lower than the reference resolution P, and one of N (where N is an integer equal to or smaller than M−1) segmented partial images has a resolution equal to or lower than a resolution R, segmenting image data into L (where L is an integer equal to or greater than N+1 and equal to or smaller than M) pieces of image data and processing image data corresponding to the partial images in parallel;
• and
• reconstructing the display image on the basis of processed image data corresponding to the M or L partial images.
