Embodiment Construction

[0050]The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0051] Such as figure 1 As shown, a low-power image display driving method based on histogram correction, comprising the following steps:

[0052] ① Input image;

[0053] ② Obtain the histogram of the R, G, and B three primary color channels in the image;

[0054] ③ Correct the histogram in step ② to obtain the corrected histogram; through the histogram correction, reducing the number of high-gray-scale pixels and increasing the number of low-gray-scale pixels is the fundamental principle of low-power processing; It is divided into the following steps (the R, G, and B channels of the original image are processed according to the following steps to achieve histogram correction):

[0055] (3.1) Calculate the corrected spacing of the histogram in step ② respectively: Among them, D is the correction distance, H max is the maximum ...

Abstract

The present invention provides a low-power image display driving method based on histogram correction, comprising the following steps: inputting an image - obtaining the histogram of the R, G, and B three primary color channels in the image - correcting the histogram, obtaining the corrected Histogram of —Match the histogram of the original image with the corrected histogram—Output the matched histogram. The invention maintains the visual effect while realizing power consumption limitation; unlike the traditional algorithm which eliminates all highlighted pixels, this method proposes a low power consumption histogram correction method, which realizes power consumption by reducing the number of highlighted pixels At the same time, the visual effect is improved by retaining some bright pixels, and it is the first time that the histogram matching method is applied to the power consumption limit of the image, which achieves excellent processing effects; the histogram of the input image is adjusted by histogram matching into a modified histogram shape, realizing low-power image processing.

Description

technical field [0001] The invention relates to a low power consumption image display driving method based on histogram correction, which belongs to the field of image enhancement and the field of consumer electronics. Background technique [0002] At present, consumer electronic products represented by smart phones have brought great convenience to daily life. However, due to the limited battery power of the mobile phone, the frequent charging problem caused by the excessive power consumption of the display panel seriously affects the user experience. Compared with the traditional display panel, the active matrix organic light emitting diode (AMOLED, Active-matrix organic light emitting diode) The panel has the advantages of omnidirectional 180° viewing angle, fast response speed, and easy ultra-thin design. It is a flat panel display technology with strong customization, the highest added value of independent intellectual property rights, the most investment development va...
