Gamma correction-based graying treatment system

Abstract

The invention relates to a Gamma correction-based graying treatment system comprising a Gamma correction device, a graying device and a gray scale statistics device, wherein the Gamma correction device is used for receiving a denoised image, the denoised image is subjected to Gamma correction operation so as to obtain and output a corrected image, the graying device is connected with the Gamma correction device and is used for receiving the corrected image, the corrected image is subjected to graying treatment so as to obtain and output a grayed image, the gray scale statistics device is connected with the graying device and is used for receiving the grayed image, gray values of all pixels are extracted from the grayed image, and an average gray value of the grayed image can be determined based on the gray values of all the pixels. Via the Gamma correction-based graying treatment system, image graying treatment precision can be improved.

Description

technical field [0001] The invention relates to the field of grayscale processing, in particular to a grayscale processing system based on gamma correction. Background technique [0002] Blinds have the following functions: [0003] 1. Beautiful and energy-saving, concise and neat, the blinds can be completely retracted, the scenery outside the window is unobstructed, and the windows are simple and generous. Curtains occupy part of the space of the windows, which affects the width of the visual windows of the house, making it cumbersome. [0004] 2. To protect privacy, use the concave and convex direction of the blade to block the outside line of sight. At the same time of lighting, it blocks the outside line of sight from top to bottom. At night, if the convexity of the blade faces indoors, the shadow will not be reflected outdoors, which is clean and easy to clean. , Usually just wipe with a rag, use neutral lotion when cleaning, do not worry about fading, discoloration w...

Problems solved by technology

[0007] At present, the control scheme for windows including blinds is still artificial, that is, people move to control the opening mode of the windows according to their own body sensations. For example, when people feel stuffy, they open the windows for ventilation. Manually open the window when the indoor ambient brightness is much lower than the outdoor ambient brightness, and manually close the window when the outdoor temperature is high. This manual control method is too inefficient and not very accurate.

[0008] At the same time, the existing window opening control scheme lacks an effective linkage mechanism with other electronic devices, and cannot meet people's requirements for the environment to the greatest extent. In addition, the existing window opening control scheme lacks some necessary parameter detection equipment, resulting in Some needs of people are difficult to be met through the control of the form
