Fig. 1 is a schematic flow chart of a display control method according to an embodiment of the present invention. The display control method 100 of fig. 1 is executed by an electronic device, which may be a mobile phone, a tablet computer, or other touch device. The display control method 100 includes:
110: when detecting that the human body part is arranged in the human body characteristic acquisition area of the screen: adjusting the brightness display of the screen to switch from a first brightness value to a second brightness value, wherein the second brightness value is higher than the first brightness value;
120: and adjusting the display image of at least part of the display area of the screen to switch from the first image to a second image capable of reducing the display brightness of at least part of the display area, wherein the second image has a transparency parameter.
It will be appreciated that the body part may preferably be the surface of any skin having identifiable characteristics, such as a fingerprint, or the like. The human body feature acquisition area corresponds to a sensor for detecting human body biological features. The display area refers to a non-human feature acquisition area in a screen. The brightness Display of the screen may be adjusted in various ways, for example, an LCD (Liquid Crystal Display) backlight or an OLED (Organic Light-Emitting Diode) backlight may be used. Wherein adjusting the display image of at least a portion of the display area of the screen may include: the mask with a certain alpha channel value (transparency value) is displayed on the front layer of the picture of the first image, namely, the mask is influenced by the transparency value of the mask, and certain high-brightness light rays can be shielded from being emitted out of the screen. Preferably, the alpha value ═ (luminance value of highlight-current lcd backlight value)/luminance value of highlight; or replacing the picture of the first image with the picture of the second image while canceling the picture of the first image in a mode of not overlapping layers, wherein in this case, the transparency of the picture of the first image is higher than that of the picture of the second image. Preferably, the displayed image is adjusted over all non-human feature acquisition areas.
Preferably, the display image of at least a part of the display area of the screen is adjusted simultaneously with or before the adjustment of the luminance display of the screen.
In addition, before the detecting that the human body part is placed in the human body feature collecting area of the screen, the method may further include: and displaying a prompt picture in the human body characteristic acquisition area, wherein the transparency parameter of the prompt picture is higher than that of the second image. The prompting picture can be cancelled after the human body part is detected to be arranged in the human body feature acquisition area of the screen. Preferably, the prompting picture is dismissed before the brightness display of the screen is adjusted. Therefore, the human biological features can be better acquired when the backlight is in the highlight mode.
Further, after the adjusting the brightness display of the screen, the method may further include: and acquiring a human body biological characteristic image from the human body characteristic acquisition area by using a sensor, and detecting.

The display control method 100 according to fig. 1, further comprising: acquiring a first brightness value and a second brightness value; the transparency of the second image is determined from the luminance values. For example, in a case where the front layer of the picture of the first image displays a mask having a certain alpha channel value (transparency value), the alpha channel value may be a function negatively correlated with the first luminance value or a function positively correlated with the second luminance value, which is not limited in this embodiment. In this case, the user does not feel the change in brightness, and the user experience is ensured while the recognition efficiency is ensured. In addition, when the method of not superimposing layers is adopted, that is, when the picture of the first image is removed and replaced with the picture of the second image, the transparency of the picture of the first image is higher than the transparency of the picture of the second image, and the transparency of the second image may be a function negatively correlated with the first luminance value or a function positively correlated with the second luminance value, which is not limited in this embodiment.
