Abstract

An image processing method applied to an image processing device, the image processing method includes following steps: receiving an original wide-angle image, pre-processing the original wide-angle image and capturing at least a region of interesting (ROI); executing anti-distorting processing on the ROI to generate a local correction image; and executing image processing on the local correction image. In the image processing method, parts of ROI of the original wide-angle image is captured, anti-distorting processing and image processing are executed, which significantly improves the image processing efficiency and reduces the time consumption instead of executing anti-distorting processing on the ROI directly.

Claims

1. An image processing method, applied to an image processing device, the image processing method comprising following steps:

receiving an original wide-angle image, pre-processing the original wide-angle image and capturing at least a region of interesting (ROI);

executing anti-distorting processing on the ROI to generate a local correction image; and

executing image processing on the local correction image.

2. The image processing method according to claim 1, wherein the pre-processing further includes:

searching a plurality of characteristic points of the original wide-angle image; and

capturing at least one region as the ROI, wherein the density of the characteristic points of the region exceeds a threshold value.

3. The image processing method according to claim 2, wherein the characteristic points locates at at least one boundary or at least a texture of the original wide-angle image.

4. The image processing method according to claim 1, wherein the pre-processing further includes:

recognizing color or grayscale value of the original wide-angle image, and

capturing at least one region having similar color or similar gray scale as the ROI.

5. The image processing method according to claim 1, wherein the pre-processing further includes;

recognizing at least one moving region of the original wide-angle image as the ROI.

6. The image processing method according to claim 1, wherein the image processing further includes:

comparing the local correction image with a database to have one or a combination of scene recognition, human recognition, object recognition.

7. The image processing method according to claim 1, wherein the image processing method further includes:

executing anti-distorting processing on the original wide-angle image to generate a panoramic correction image when the ROI fails to be captured; and

executing image processing on the panoramic correction image.
