Abstract: The present disclosure provides a method and a system for enhancing an image, and a computer readable storage medium. The method includes: obtaining coding information, histogram distribution information, and a signal characteristic parameter of a display content of the image after detecting a frame signal of the display content (S1); querying a preset first Look-Up-Table (LUT) according to the coding information of the display content to obtain a corresponding control parameter (S2); processing the histogram distribution information according to the control parameter and the signal characteristic parameter to obtain a processed histogram distribution information (S3); obtaining an average product length (APL) control value according to the processed histogram distribution information (S4); and enhancing the image according to the APL control value (S5). Compared with the related arts, the present disclosure improves the image display effect and the user experience without increasing the hardware cost.

Abstract: Disclosed is a backlight driving control method and system applied to a display terminal having an LCD. The display terminal includes a MCU and a backlight, the backlight includes multiple light bars composed of LED lights and multiple driving ICs, each driving IC controls one or more light bars. The method includes: in response to reception of respective electrical signals of the LED lights, demodulating, by the MCU, the electrical signals to obtain respective brightness values of the LED lights; comparing the respective brightness values of the LED lights in each driving IC to obtain a maximum brightness value of the LED lights in the driving IC; and dividing the maximum brightness values of the LED lights in the driving ICs into multiple brightness intervals, determining a current value corresponding to each brightness interval, and controlling the brightness of the LED lights in the driving ICs according to the current values.

Abstract: The present disclosure provides a method for adjusting display image contrast, which includes the following operations: in response to receiving an image signal, acquiring an image to be displayed and metadata according to the image signal, and calculating a signal amplitude corresponding to each pixel of the image to be displayed; generating a histogram showing a distribution of the signal amplitude according to each of the signal amplitudes, and acquiring display information and a backlight adjustment parameter of the image to be displayed according to the histogram; generating a signal adjustment function according to the display information, the backlight adjustment parameter, and the metadata, and adjusting the signal amplitude of each of the pixels according to the signal adjustment function to adjust a contrast of the image to be displayed. The present disclosure further provides a display and a readable storage medium. The cost of improving the display image contrast of the present application is low.
