Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Because human eyes perceive brightness nonlinearly, under a scene with large brightness change amplitude in a short time, for example, when the user walks from a bright hall to the outdoors at night, if the screen backlight brightness is adjusted according to a constant rate, the screen brightness is not matched with the human eye perception sensitivity, and the user experience is influenced.
In order to solve the above problem, embodiments of the present invention provide a screen brightness adjusting method and apparatus. By carrying out variable speed adjustment in the human eye dark adaptation process, the human eye light sensation change process from bright vision to dark vision is adapted, and the problem that screen brightness is not matched with human eye perception sensitivity so as to influence user experience is solved.
An embodiment of the present invention provides a screen brightness adjustment method, and provides a backlight adjustment model constructed according to a human eye model, which is suitable for devices with screens (such as mobile terminals like mobile phones), and can effectively improve user experience. The flow of completing the screen brightness adjustment by using the method is shown in fig. 1, and comprises the following steps:
step 101, when detecting that the ambient brightness changes, determining that the brightness of a target screen needs to be adjusted;
and when the detected ambient brightness change amplitude reaches a preset adjustment threshold, determining the brightness of the target screen to be adjusted according to the current ambient brightness.
And 102, sequentially performing brightness adjustment of the first stage and brightness adjustment of the second stage to achieve the purpose that the brightness of the target screen needs to be adjusted.
The human eye adapts to the brightness change at different speeds under different brightness environments, and referring to fig. 2, the time consumed for the human eye to adapt from high brightness (approximately 700nit) to low brightness (approximately 0nit) is consumed. It can be seen that the adaptation speed of human eyes to brightness change is fast in the range of higher brightness; and in the range of lower brightness, the adaptation speed is slower.
Therefore, in this step, when the brightness of the target screen needs to be adjusted, the adjustment is performed in two stages, namely, a first stage and a second stage. The brightness adjusting in the first stage and the second stage uses different brightness change rates, specifically, the average brightness change rate in the first stage is greater than that in the second stage when the ambient brightness changes from bright to dark. Therefore, in the process of dark adaptation of human eyes, the screen brightness is quickly and greatly reduced in the first stage, and then the brightness is slowly adjusted to the final target screen in the second stage and needs to be adjusted, so that the regulation of the brightness of the target screen is matched with the regulation of the human eye photosensitive adjustment, and the situation that a user feels uncomfortable due to the fact that the screen brightness is not matched with the environment is avoided. Generally, the brightness adjustment amplitude of the brightness adjustment in the first stage is larger than that in the second stage.
Further, in order to make the screen brightness adjustment scheme provided by the embodiment of the present invention more suitable for the human eye photosensitive adjustment rule, when the first stage and the second stage are divided, the conversion brightness is taken as a boundary point, the brightness change range from the initial screen brightness to the conversion brightness is taken as the brightness adjustment range of the first stage, and the brightness change range from the conversion brightness to the target screen, the brightness of which needs to be adjusted, is taken as the brightness adjustment range of the second stage.
Wherein the conversion brightness is a brightness taken from a range of photopic vision, scotopic vision and conversion positions in the human eye dark adaptation process. Referring to fig. 2, a luminance value between 200nit and 100nit may be generally selected as the value of the converted luminance.
An embodiment of the present invention further provides a screen brightness adjusting apparatus, which is shown in fig. 3 and includes:
the target brightness determining module 301 is configured to determine that brightness of a target screen needs to be adjusted when it is detected that ambient brightness changes;
the segment adjusting module 302 is configured to perform brightness adjustment in a first stage and brightness adjustment in a second stage in sequence to achieve brightness adjustment required for the target screen, where brightness change rates used for the brightness adjustment in the first stage and the brightness adjustment in the second stage are different.
Preferably, the segment adjustment module 302 is specifically configured to, in a case where the ambient brightness changes from bright to dark, increase an average rate of brightness change of the brightness adjustment in the first stage to be greater than that of the brightness adjustment in the second stage.
Preferably, the segment adjusting module 302 is further configured to use a brightness change range from an initial screen brightness to a conversion brightness as the brightness adjustment range for the brightness adjustment in the first stage, and use a brightness change range from the conversion brightness to the target screen brightness that needs to be adjusted as the brightness adjustment range for the brightness adjustment in the second stage, where the conversion brightness is brightness of photopic vision, scotopic vision and a conversion position in the human eye dark adaptation process.
The embodiment of the present invention provides a backlight brightness adjusting apparatus, which can be combined with the backlight brightness adjusting method provided by the embodiment of the present invention, when detecting that ambient brightness changes, determine brightness of a target screen to be adjusted, and sequentially perform brightness adjustment of a first stage and brightness adjustment of a second stage to achieve the brightness of the target screen to be adjusted, where brightness change rates used for the brightness adjustment of the first stage and the brightness adjustment of the second stage are different. The screen brightness adjusting device is adaptive to the characteristic that human eyes adjust speed change in the adaptive process of brightness change, the problem that the screen brightness is not matched with human eye perception sensitivity so that user experience is influenced is solved, and comfortable and natural screen brightness adjustment is achieved.
For example, in the dark adaptation process, the automatic backlight adjustment is performed according to the brightness adaptation rate of the human eye model, and the automatic backlight adjustment is performed first to a certain brightness to adapt to the current dark environment and then is performed slowly. Human eyes are sensitive to dim light and dim light, and can be adjusted according to the adjusting speed, so that the human eyes are comfortable and natural, the discomfort of dazzling or too dark can be avoided, and the user experience can be greatly improved.
