Abstract
An image processing method adapted to be executed by an image capturing apparatus. The image capturing apparatus comprises a processing circuit and a light field camera. The image processing method includes: obtaining by using the light field camera a first image and a second image each including a plurality of sub-regions; performing a local brightness redistribution process on at least one of the sub-regions of the second image according to a brightness distribution of at least one of the sub-regions of the first image; performing an image rendering process on the first image and the second image to obtain a third image; and performing a global brightness redistribution process on the third image to obtain a fourth image.
Claims15
An image processing method adapted to be executed by an image capturing apparatus comprised a processing circuit and a light field camera electrically connected with the processing circuit, the image processing method comprising:
- obtaining a first image and a second image by using the light field camera, wherein each of the first image and the second image comprises a plurality of sub-regions;
- determining brightness of each of the sub-regions of the second image saturated or higher than a predetermined threshold;
- recording the locations of the determined sub-regions of the second image;
- performing a local brightness redistribution process on at least one of the sub-regions of the second image according to a brightness distribution of at least one of the sub-regions of the first image to obtain a third image;
- and
- performing a global brightness redistribution process on the third image to obtain a fourth image.
