Problems solved by technology

However, not all the TVs that actually leave the factory can meet this standard, especially for CRT TVs. With the aging of the scanning circuit and the different brightness of the image, the redisplay rate will change greatly, resulting in image loss. increased so that the user cannot view the full image
[0003] However, it is necessary to adjust the software and hardware parameters of the TV itself (the hardware parameters of the TV scanning circuit and adjust the TV display related registers) to adjust the redisplay rate of the TV, and such adjustments are all set before the TV leaves the factory. Yes, ordinary users cannot enter the factory mode of the TV to adjust the redisplay rate
Therefore, when an ordinary user finds that the TV cannot present a complete image, at most the corresponding manufacturer can only enter the factory mode to adjust the re-display rate through door-to-door maintenance, but this adjustment is common for CRT TVs. It will bring geometric distortion of the image (including image distortion, etc.), reducing the display quality of the image

Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0039] In order to facilitate the understanding of the technical solutions provided by the embodiments of the present invention, the following explanations are first made:

[0040] (1) The reason why the image reproduction rate of the TV does not reach 100% is that the scanning circuit of the analog TV is not linear (especially near the edge), which causes serious distortion of the edge of the TV image. The distorted part of the image appears on the edge of the screen. Overscan technology is ...

Abstract

The invention discloses a method and device for adjusting image integrity of a television. The method comprises the following steps of: when receiving a request of adjusting the image integrity, outputting a reference image with a scale mark to a television screen; according to the adjusting operation of a user, modifying the display position of the scale mark on the television screen; when the adjusting operation is finished, recording the adjusting direction and the number of pixels, and adjusting the position and the size of a video output window according to the direction and the number of the pixels to adjust the image integrity of the television in real time. With the method and the device, the user can adjust the television image integrity according to the requirement per se, and other performances of the television can not be influenced in the adjusting process.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method and device for adjusting the integrity of television images. Background technique [0002] The redisplay rate is an important indicator of TV image testing, which refers to the ratio of the image program reproduced on the TV screen to the image program sent by the TV station, that is, the percentage of effective images that can actually be displayed on the screen. The redisplay rate is divided into vertical redisplay rate and horizontal redisplay rate. For example, the horizontal effective image pixel is 720, but 680 points are actually displayed, and the horizontal redisplay rate is 680 / 720. In order not to affect normal viewing, the general redisplay rate should be greater than or equal to 95%. However, not all the TVs that actually leave the factory can meet this standard, especially for CRT TVs. With the aging of the scanning circuit and the different bri...
