Problems solved by technology

The processing results of the 2005 / 0100240A1 case can effectively enhance the edge processing in the image, but after the original image undergoes the above-mentioned various image processing, many details in the original image will be destroyed, resulting in unclear image details
For example, when the gamma correction process is performed, the high-brightness areas of the image are compressed, resulting in the loss of high-brightness details in the image
Therefore, after being processed by the above-mentioned various programs, various details of the original image will be severely damaged.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0026] The method for compensating the details of a digital image of the present invention is applied to compensating the image details of an original image when a digital camera device captures the original image. The digital camera device can be, for example, a digital camera, a digital video camera, a digital photo frame, or a personal computer connected with a digital capture device, and the like. However, it should be noted that the present invention is not limited to the above-mentioned limitation, which is described here first.

[0027] Please refer to figure 2 As shown, a specific implementation aspect of the present invention comprises the following steps:

[0028] Step a. Loading the aforementioned original image captured by the digital camera device;

[0029] Step b. passing the original image through at least o...

Abstract

The invention relates to a method for compensating details of a digital image, which is applied to compensate the details of an original image picked up by a digital pick-up device. The method comprises the steps of: loading the original image, carrying out at least one image treatment procedure for the original image to generate a temporary storage image, storing detail data of the temporary storage image, meanwhile, carrying out at least one image conversion program for the temporary storage image selectively, and carrying out a mixing program for the temporary storage image subjected to the image conversion program and the detail data stored in advance to obtain a complete image.

Description

technical field [0001] The invention relates to a digital image processing method, in particular to a digital image detail compensation method. Background technique [0002] In the existing image processing flow, after obtaining the original image (raw data) 110 from the photosensitive element, it will go through the image automatic white balance program (auto white balance) 120, the color filter matrix interpolation point program (color filter array interpolation) in sequence ) 130, color correction matrix program (color correction matrix) 140, gamma correction program (gamma correction) 150, color gamut conversion program (RGB2YCC) 160 and sharpening program (Sharpness) 170, and finally output a completed image 180 . please cooperate figure 1 As shown, it is a schematic diagram of the operation flow of the prior art. [0003] US Patent No. 2005 / 0100240A1 is an image edge enhancement system and method thereof. In the 2005 / 0100240A1 case, it is disclosed that the origina...
