Embodiment Construction
[0032] As mentioned in the background art, there is an urgent need to propose an image display method that can reduce backlight power consumption while avoiding situations such as flickering, thereby improving the display effect.
[0033] The inventors of the present invention found through research that, in the prior art, the power consumption of the backlight is reduced by adjusting the backlight of each frame of image. Specifically, the backlight value of each frame image is determined solely according to the brightness value of the frame image. With this prior art, phenomena such as sudden over-brightness, sudden over-darkness, bright and dark flickering are prone to occur during video playback, and the display effect is relatively poor.
[0034] In order to solve the above technical problems, the embodiments of the present invention provide a method to make the above objects, features and beneficial effects of the present invention more obvious and understandable. The spe...

The invention discloses an image display method and device, a storage medium and a terminal. The method comprises the steps: obtaining a current frame image, and determining a backlight estimation value of the current frame image according to the brightness value of a pixel point in the current frame image; calculating a brightness statistical value of the current frame image according to the brightness value of the pixel point in the current frame image and the brightness value of the pixel point in the previous frame image, and judging whether the current frame image is a gradient scene frame according to the brightness statistical value of the current frame image; if the judgment result is yes, determining a backlight adjustment step value of the current frame image according to the brightness statistical value of the current frame image, and determining a backlight value of the current frame image; and performing backlight compensation on the current frame image according to the backlight value of the current frame image. By adopting the scheme, the condition of splash screen can be avoided when the backlight power consumption is reduced, so that the display efficiency is improved.
Description
technical field [0001] The present invention relates to the field of computer vision, in particular to an image display method and device, a storage medium and a terminal. Background technique [0002] Power consumption is an important aspect that affects the standby time of a terminal (for example, a mobile phone, a tablet computer, a computer, etc.), and is also an important factor that affects user experience. With the development of society and the advancement of technology, watching videos on terminals has become the main way of entertainment for the public. Wherein, the power consumption of the backlight of the terminal when playing video accounts for about 50% of the power consumption of the entire terminal, so saving the power consumption of the backlight of the terminal is an effective way to save power consumption. [0003] In the prior art, backlight power consumption is usually reduced by adjusting the backlight value of each frame of image. Specifically, the b...
