Problems solved by technology
[0004] However, these methods have certain defects. Taking simply changing the light transmission as an example, if you want to get the effect of darker black and brighter brighter, you must put forward higher requirements for the power supply, and the power supply control must be more precise and detailed. In order to achieve a darker effect, higher power consumption is required to achieve an increase in brightness; in addition, the level of requirements for the panel must also be increased, which will inevitably lead to a corresponding increase in cost
[0005] In addition, there are many solutions to achieve the goal of image enhancement by changing the electrical transmission, but such methods often sacrifice the details of the signal inappropriately, resulting in an incomplete picture presentation that cannot truly convey the director's true intentions

Embodiment Construction
[0064] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0065] The main solution of the embodiment of the present invention is: when the frame signal of the current image display content is detected, obtain the encoding information, histogram distribution information and signal characteristic parameters of the display content; query according to the encoding information of the display content The preset first LUT table is used to obtain corresponding control parameters; the histogram distribution information is processed according to the control parameters and signal characteristic parameters to obtain processed histogram distribution information; according to the processed histogram The distribution information obtains an APL control value; and the image is enhanced according to the APL control value. In this way, on the premise of not increasing the hardware cost, the pi...

The invention discloses an image enhancement method, a system and a computer-readable storage medium. The method comprises the following steps: when a frame signal of a current image display content is detected, coding information, histogram distribution information and signal characteristic parameters of the display content are obtained; when the frame signal of the current image display contentis detected, the histogram distribution information and the signal characteristic parameters are obtained. Querying a preset first LUT table according to the coding information of the display contentto obtain corresponding control parameters; processing the histogram distribution information according to the control parameter and the signal characteristic parameter to obtain the processed histogram distribution information; obtaining an APL control value according to the processed histogram distribution information; the image is enhanced according to the APL control value. Compared with the prior art, the invention improves the screen display effect and the user experience without increasing the hardware cost.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an APL-based image enhancement method, system and computer-readable storage medium. Background technique [0002] Image enhancement technology has always been an important research direction of many display manufacturers, because proper image enhancement is conducive to improving the image quality performance of the display, making the picture layered better and the three-dimensional effect deeper. [0003] There are many image enhancement technology solutions applied to displays, but in principle, they are all realized by changing optical transmission, or electrical transmission, or a combination of the two. [0004] However, these methods have certain defects. Taking simply changing the light transmission as an example, if you want to get the effect of darker black and brighter brighter, you must put forward higher requirements for the power supply, and the pow...
