Embodiment 1
[0082] refer to figure 2 , Embodiment 1 of the present invention provides a method for optimizing image quality, the method for optimizing image quality includes:
[0083] S100, acquiring display data of a currently displayed image;
[0084] Specifically, the currently displayed image is a certain frame of image displayed on the display, and the frame of image can be a certain frame of image intercepted from a video, or can come from a separate image file, and the display data is extracted from the currently displayed image. Information.
[0085] S200. Determine the average brightness and target duty cycle of the currently displayed image according to the display data;
[0086] Specifically, the display data includes the average brightness and the target duty cycle. The average brightness is the average brightness of all pixels in the currently displayed image. The target duty cycle refers to the duty cycle used to determine the target brightness. The duty cycle is within a...
Embodiment 2
[0094] Please refer to image 3 , the above step S200 includes:
[0095] S210. Obtain the brightness information of each of the partitions in the currently displayed image;
[0096] Specifically, the currently displayed image includes multiple partitions, each partition is composed of multiple pixels, and each partition includes brightness information of each pixel, and also includes brightness information of the partition determined by the brightness information of each pixel.
[0097] In some optional implementations, each pixel in the currently displayed image includes three sub-pixels of red, green, and blue, each sub-pixel is used to process a color channel, and each sub-pixel corresponds to a Grayscale value, according to the grayscale value to determine the brightness of the pixel, for example, the maximum value among the three grayscale values corresponding to the three sub-pixels of each pixel can be determined as the maximum grayscale value of the pixel, and the p...
Embodiment 3
[0103] Please refer to Figure 4 , in Embodiment 1, the above step S200 also includes:
[0104] S230. Obtain the duty cycle of each of the partitions in the currently displayed image;
[0105] Specifically, the duty cycle represents the ratio of the duration of the positive pulse representing 1 to the total pulse cycle in a series of pulse sequences. The current display image contains multiple partitions, and the duty cycle of the partition is determined by the brightness of each partition .
[0106]In some optional embodiments, a liquid crystal panel is used as the display, and the backlight source material of the liquid crystal panel is a light emitting diode (Light Emitting Diode, LED), and the LED is modulated to emit visible light, and the modulation method includes amplitude modulation (Amplitude Modulation) Modulation, AM) and Pulse Width Modulation (Pulse WidthModulation, PWM), because PWM has the characteristics of high color control accuracy, it is suitable for the...
