Problems solved by technology

With the wide application of various smart devices, people have higher and higher requirements for the contrast ratio of the display screen. In related technologies, the contrast ratio of mobile devices is generally set and will not be easily changed. In the scene, for example, in the scene where the screen brightness is lower than 5 nits, the attention of the human eye to the display details will be greatly reduced, but the visibility will be more concerned. If the contrast of the displayed content cannot be improved, the displayed content may be blurred , the readability and comfort are very low, which directly affects the user experience of using smart devices

Embodiment Construction

[0078] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0079] figure 1 It is a flow chart of a contrast enhancement method shown according to an exemplary embodiment; the contrast enhancement method can be applied to mobile devices (such as tablet computers, smart phones, smart cameras), such as figure 1 As shown, the contrast enhancement method includes the following steps:

[0080] In step 101, when the mobile device works in a preset display mo...

Abstract

The invention relates to a comparison-ratio increasing method and device. The comparison-ratio increasing method includes the steps that when a mobile device works in a preset display mode, the gray level distribution information of a to-be-displayed frame is determined, and the preset display mode is a night-light display mode for showing that the screen luminance is lower than a preset luminance threshold value; according to the gray level distribution information, a comparison-ratio adjustment curve of the to-be-displayed frame is determined; according to the comparison-ratio adjustment curve, the comparison ratio of the to-be-displayed frame is increased. By means of the comparison-ratio increasing method and device in the technical scheme, the comparison-ratio adjustment curve of the to-be-displayed frame can be automatically determined, the comparison ratio of the to-be-displayed frame is further increased, the readability of the display content is improved, and the problem that as the comparison ratio of the display content cannot be increased in the related technology, the display content is fuzzy is solved.

Description

technical field [0001] The present disclosure relates to the technical field of screen display, and in particular to a method and device for enhancing contrast. Background technique [0002] Currently, display screens are widely used in various smart devices, such as smart phones, MP3 / MP4, wearable smart watches, smart bracelets, and tablet computers. With the wide application of various smart devices, people have higher and higher requirements for the contrast ratio of the display screen. In related technologies, the contrast ratio of mobile devices is generally set and will not be easily changed. In the scene, for example, in the scene where the screen brightness is lower than 5 nits, the attention of the human eye to the display details will be greatly reduced, but the visibility will be more concerned. If the contrast of the displayed content cannot be improved, the displayed content may be blurred , the readability and comfort are very low, which directly affects the u...
