The embodiment of the invention discloses a light strength value detecting method and a terminal. The method comprises the steps that a camera is started to shoot external environment, and a shot image is obtained; the average brightness value of the shot image is compared with the average brightness values of all preset images in a preset image library one by one, a target preset image can be obtained from the preset image library, the absolute value of the difference of the average brightness value of the target preset image and the average brightness value of the shot image is the minimum, and each preset image in the preset image library carries an environment light strength value; the environment light strength value carried by the target preset image is set as the light strength value of the external environment. Therefore, through the method and the terminal, the environment light strength value can be obtained through the image shot by the terminal camera, the situation that a light-sensing IC is configured in the terminal to acquire the environment light strength value is avoided, and therefore the hardware structure of the terminal is simplified.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a light intensity value detection method and a terminal. Background technique [0002] Existing terminals with display screens (such as smart phones, IPADs, etc.) are often provided with an automatic backlight brightness adjustment function. Realizing the automatic backlight brightness adjustment function needs to obtain the current ambient light intensity value, and then adjust the backlight brightness and contrast of the screen in real time and automatically according to the obtained current ambient light intensity value. In the prior art, in order to realize the automatic backlight brightness adjustment function, a light-sensing IC (Integrated Circuit, integrated circuit) is often used to sense the light of the environment to obtain the current light intensity value of the environment. Although the light-sensing IC can realize the function of detecting the current ambient l...
