Abstract
The invention provides an image processing method. An image is provided, and the image is divided into a first subimage, a second subimage, a third subimage, and a fourth subimage according to a decomposing method. Next, the first, second, third, and fourth subimages are processed to generate a first subframe, a second subframe, a third subframe, and a fourth subframe. Finally, the first, second, third, and fourth subframes are combined as a frame according to a composing method corresponding to the decomposing method.
Claims21
An image processing method, comprising:
- acquiring an image;
- dividing the image into a first subimage, a second subimage, a third subimage, and a fourth subimage according to a decomposing method;
- executing an image process onto the first, second, third, and fourth subimages to respectively generate a first subframe, a second subframe, a third subframe, and a fourth subframe;
- and
- combining the first, second, third, and fourth subframes as a frame according to a composing method corresponding to the decomposing method,
- wherein only one of the first, second, third, and fourth subimages is executed at one time, and
- wherein the first, second, third, and fourth subimages are respectively composed of a plurality of pixel rows, and one of the following operations is respectively executed on the pixel rows at the same time:
- executing one of the image processes;
- storing to the first, second, third, or fourth subframe when the image process is executed;
- and
- staying idle,
- wherein the storing operation is executed on only one of the pixel rows.
An image processing method, comprising:
- acquiring an image;
- dividing the image into a first subimage, a second subimage, a third subimage, and a fourth subimage according to a decomposing method;
- executing an image process onto the first, second, third, and fourth subimages to respectively generate a first subframe, a second subframe, a third subframe, and a fourth subframe;
- combining the first, second, third, and fourth subframes as a frame according to a composing method corresponding to the decomposing method;
- executing a second image process onto the first subimage to generate a fifth subframe;
- and
- combining the second, third, fourth, and fifth subframes as a second image according to the composing method,
- wherein only one of the first, second, third, and fourth subimages is executed at one time, and
- wherein the first, second, third, and fourth subimages are respectively composed of a plurality of pixel rows, and one of the following operations is respectively executed on the pixel rows at the same time:
- executing one of the image processes;
- storing to the first, second, third, or fourth subframe when the image process is executed;
- and
- staying idle,
- wherein the storing operation is executed on only one of the pixel rows.
An image processing system, comprising:
- a storage device configured to store a plurality of images, wherein the images respectively composing of a plurality of pixel rows;
- a plurality of processing circuits respectively configured to read the image from the storage device and execute an image process, wherein each of the processing circuits processes one of the pixel rows at a time;
- a plurality of row buffers configured to store the processed pixel rows;
- a plurality of subframe buffers configured to read the processed pixel rows from the row buffers to compose a plurality of subframes;
- and
- a display circuit configured to read the subframes from the subframe buffers, combine the subframes to generate a frame according to a composing method, and convert the frame to a display signal.
