Problems solved by technology

[0002] At present, the TV design does not do any technical processing for the dark field in TV programs, so users often encounter such problems: when watching a TV program with a lot of dark fields, the user will feel that the TV screen is black and the scene The objects in the image cannot be seen clearly at all, and it is easy to cause eye fatigue. The general solution for users is to manually increase the image brightness; after the image changes from dark field to bright field, then reduce the image brightness, so that users Not very convenient when watching TV programs

Embodiment Construction

[0018] The purpose of the present invention is to start the brightness compensation and automatically increase the brightness parameters when the TV program has a dark field, so that the audience can watch TV clearly; when the TV program returns to the bright field, it can automatically turn off the brightness compensation and return to normal Brightness, to prevent image highlight distortion.

[0019] The main problems that need to be solved are as follows:

[0020] 1. The distinction between dark field and bright field images.

[0021] The image signal is constantly changing. To control the brightness, the brightness value of each field must be known, but the image signal is divided into interlaced and progressive signals, so the brightness value of each frame of the image must be used as a reference. The interlaced signal is divided into 480i, 576i and 1080i, so the average brightness of a single pixel is proposed as the brightness measurement standard of a frame of image ...

Abstract

The invention discloses a method used for automatically compensating the television image brightness dark field in the field of television image technique, comprising the steps as follows: S1: the average value of single pixel brightness is calculated, namely, the brightness average value of each frame of image is used for dividing the pixel value of the frame of image; S2: the dark field image brightness compensation value is calculated, namely, for the dark field image, the brightness compensation value is gained according to the average value of single pixel brightness gained according to the S1 step; S3: the brightness is compensated; namely, the brightness compensation value gained in the S2 step is added to the current image brightness value, and then the sum of the brightness compensation value and the current image brightness value is taken as a new brightness value. The television image dark brightness automatic compensation method of the technical proposal of the invention uses the brightness average of single pixel as the brightness measurement standard of one frame of image, can be applicable to various modes and can be compatible for line-by-line and interlacing, can effectively improve the intelligence of the television, reduce the eye fatigue and meet the healthy concept of the modern.

Description

technical field [0001] The invention relates to television image brightness technology, in particular to an automatic compensation method for dark field brightness of television images. Background technique [0002] At present, the TV design does not do any technical processing for the dark field in TV programs, so users often encounter such problems: when watching a TV program with a lot of dark fields, the user will feel that the TV screen is black and the scene The objects in the image cannot be seen clearly at all, and it is easy to cause eye fatigue. The general solution for users is to manually increase the image brightness; after the image changes from dark field to bright field, then reduce the image brightness, so that users It is not very convenient when watching TV programs. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose an automatic compensation method for the brightness of the dark field of the TV ...
