The invention discloses a control method and device, imaging equipment, computer equipment and a non-volatile computer readable storage medium. The imaging equipment comprises a pixel unit array, andthe pixel unit array comprises multiple pixel units; the control method comprises the following steps: acquiring a gain index value according to an ambient brightness value of the current environmentand the preset target brightness value; when the gain index value is less than the preset gain index value, photographing by using a light mode to obtain a target image; when the gain index value is greater than the preset gain index value, photographing by using a dark mode to obtain the target image. Trough the control method and device, imaging equipment, computer equipment and the non-volatilecomputer readable storage medium disclosed by the invention, the light-dark situation of the current environment is judged by acquiring the gain index value for representing the light-dark of the environment, furthermore, the appropriate working mode is selected according to the judgment result to shoot the target image with excellent imaging effect, and the shooting experience of the user is improved.

The present invention discloses shutter glasses and a 3D display system. The shutter glasses include a first polarizer, a second polarizer, a normally-white LCD panel, and a normally-black LCD panel. A thickness of the normally-white LCD panel is not the same as a thickness of the normally-black LCD panel, and an optical compensation film is installed between the first polarizer and the liquid crystal layer of the normally-black LCD panel and / or between the second polarizer and the liquid crystal layer of the normally-black LCD panel in order to compensate for a dispersion occurred when the liquid crystal layer of the normally-black LCD panel is in a dark mode. In this way, the present invention can not only shorten the response time of the shutter glasses to reduce the power consumption, but also reduce the 3D crosstalk.

The invention provides an interface display method and device, terminal equipment and a storage medium. The interface display method comprises the steps of obtaining color parameters of a background picture in a current to-be-displayed target interface and color parameters and transparency parameters of each icon contained in the target interface in a dark mode; adjusting the color of each icon according to the color conversion rule of the target interface, the color parameter of the background picture and the color parameter and transparency parameter of each icon; and displaying a backgroundpicture of the target interface, and displaying the icon after color adjustment in the background picture. The technical problems that according to an existing interface display scheme, the color ofan icon in an interface cannot be rapidly adjusted in time in a dark mode, and the icon and the display effect of the interface in the dark mode are influenced are solved. The beneficial effect of improving the display effect of the icon and the interface by accurately adjusting the icon color in the dark mode in time is achieved.

An automatic darkening and glare reducing liquid crystal mirror for vehicles is disclosed. The mirror has a front substrate (101) of transparent glass or plastic and a back substrate (109) of glass orplastic with a highly reflective or transflective mirrored coating (108). The front and back substrates are spaced apart a small distance to define a liquid crystal cell between the substrates and aliquid crystal fluid (106) incorporating dichroic dyes is contained within the liquid crystal cell. A conductive thin film (102) is applied onto the interior surface of the front substrate and the reflective or transflective coating (108) of the back substrate also is conductive. An alignment compound is deposited on the conductive thin film (102) and on the reflective or transflective coating (108) and the alignment compound bounds the liquid crystal cell. An electronic control circuit is adapted to apply selectively a voltage signal to the conductive thin film and the reflective or transflective coating (108) to affect the transmittance of the liquid crystal fluid, and thereby the darkness of the mirror. The nature of the alignment compound determines a home or rest alignment of the liquid crystal molecules, either parallel or perpendicular to the substrates, and thus determines whether the mirror is normally dark (a 'dark mode' mirror) or normally bright (a 'bright mode' mirror). Application of a voltage signal to a dark mode mirror lightens it while application of a voltage signal to a bright mode mirror darkens the mirror. A headlight sensor (302) and an ambient sensor (301) are coupled to the electronic control circuit and the circuit is configured to darken the mirror in response to signals from the sensors indicating that the ambient light intensity is below a predetermined threshold (equivalent to nighttime) and the intensity of light from headlights impinging on the mirror is above a predetermined threshold (equivalent to a glare condition).
