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 invention provides a low-power consumption image display driving method based on histogram correction, which comprises the following steps of: inputting an image; obtaining the R, G, B primary color channel histogram in the image, correcting the histogram to get the corrected histogram, matching the histogram of the original image with the corrected histogram, and outputting the matched histogram. The invention not only realizes the power consumption limitation, but also maintains the visual effect. Unlike the traditional algorithm which eliminates all highlight pixels, a low power consumption histogram correction method is proposed in that method, the power consumption is limited by reducing the number of highlight pixels, at the same time, the visual effect is improved by reserving part of highlight pixels, and the histogram matching method is applied to the power consumption limitation of an image for the first time, so that the excellent processing effect is realized; the histogram of the input image is adjusted to a modified histogram shape by histogram matching, which realizes the image processing with low power consumption.

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...
