Colorful automatic control method

Abstract

The invention realizes image colorfulness control by software and realizes the automatic colorfulness regulation of video products, such as TV sets, etc. on the premise that no extra cost is required. Particularly, the automatic colorfulness control method of the invention comprises the steps as follows: image signals are received; color synchronizing signal amplitude information of the image signals is obtained; the size of the color synchronizing signal amplitude is judged; if the color synchronizing signal amplitude is within a preset range, colorfulness yield value is calculated accordingto the color synchronizing signal amplitude; if the color synchronizing signal amplitude is beyond the preset range, the color yield value is set to be a fixed value; the color intensity of an image is controlled according to the color yield value. The automatic colorfulness control method of the invention realizes the automatic colorfulness control of video equipment on the premise that no extracost is required, with strong real-time property and adjustability, and by using the method, any colorfulness control effect required by a designer can be set, thus leading to the more accurate and natural color reproduction of the images of the video equipment, such as the TV sets, etc.

Description

technical field [0001] The invention relates to a color automatic control method, more specifically to a color automatic control method for video equipment. Background technique [0002] With the improvement of living standards and the continuous development of video technology, various video devices emerge in an endless stream, and their functions are also increasing. At the same time, users have higher and higher requirements for video devices. Taking TV as an example, with the continuous development of TV technology, the function of TV is more and more powerful, from the original one that can only watch TV programs to the multifunctional TV that can play multiple media now. However, the pursuit of clarity is still the main goal of most TV users. Many users spend a lot of money to buy the latest and various new TV products in order to make the display of the TV better. However, the quality of the TV display is not only directly related to the quality of the TV itself, but...

Problems solved by technology

At the same time, due to the difference between the signal generating equipment and the signal environment, the signal sent by the signal source will not be standard enough

Non-standard signal amplitude or color burst amplitude of the signal will cause image color deviation, such as thick or light phenomenon

When the color synchronization amplitude is lower than the standard, the image color will be light, and when the synchronization amplitude is higher than the standard, the image color will be too dark

[0005] For the above defects, the current common solution is to adjust the color by adding corresponding hardware. Due to the increase of hardware equipment, the production cost of the TV is inevitably increased , therefore, the art needs a low-cost solution to the problem of color inaccuracy of video equipment
