The method includes: choosing content-associated sub pixels in an image to be processed; obtaining an initial color level value of each of the content-associated sub pixels in the image to be processed; adding to least one digit to an end of the initial color level value and assigning a preset value to each added digit so as to obtain a processed color level value; and replacing the initial color level value with the processed color level value.
Abstract:
The present disclosure relates to a method and an apparatus for single-hand operation on a full screen of a smart device, which pertains to the field of computer technology. The method for single-hand operation on a full screen includes determining whether a single-hand operation mode is activated, displaying a cursor indicator on the screen of the smart device when the single-hand operation is activated, moving the cursor indicator based on a track generated by a sliding operation on the screen of the smart device, determining whether the cursor indicator is moved into a trigger region, and activating the trigger region to receive an instruction associated with a touch event on the screen when the cursor indicator is moved into the trigger region. The touch event locates outside the trigger region.
Abstract:
A method for determining a spatial parameter for an object displayed on a device includes determining a first pixel coordinate corresponding to a first point of an image of the object and a second pixel coordinate corresponding to a second point of an image of the object displayed on the device, determining an image distance between the first pixel coordinate and the second pixel coordinate, and determining a spatial parameter for the object based on a distance between an imaging element of the device and the object, and a focal length of a lens of the imaging element for photographing the object. According to the technical solution of the present disclosure, the real size of the photographed object can be quantized based on the image, without having to illustrating the real size of the photographed object in contrast with a reference object placed in the image, thereby improving the user experience.
Abstract:
A method and a device for adjusting a colour temperature are disclosed. The method includes acquiring a colour coordinate value of a pixel in a Liquid Crystal Display (LCD) is acquired when the LCD displays a white screen, determining whether the colour coordinate value is within a predetermined colour coordinate range corresponding to a predetermined colour temperature of the LCD, and adjusting, if the colour coordinate value is not within the predetermined colour coordinate range, a component value of at least one LED of N LEDs corresponding to the pixel until a changed colour coordinate value of the pixel due to the adjustment falls within the predetermined colour coordinate range.
Abstract:
A method, device, and computer-readable storage medium are provided for image display. The method includes: obtaining display definition information of an image to be displayed; determining a target image compression ratio corresponding to the display definition information of the image to be displayed based on a prestored correspondence between display definition information and image compression ratios; and compressing display data of the image to be displayed based on the target image compression ratio, and transmitting the compressed display data to a display device for display.
Abstract:
The present disclosure discloses a liquid crystal display method and device, and a storage medium, and it relates to the field of liquid crystal display. The method include acquiring a grayscale value of each row of a content displayed on a liquid crystal panel, determining whether the pixel grayscale values of a plurality the pixels in the i-th row of the displayed content are lower than a predetermined value, setting a refresh rate of the i-th row of the displayed content to a first refresh rate when the grayscale values of the plurality of pixels in the i-th row are below the predetermined value, determining whether at least one pixel grayscale value of the pixels in the j-th row is not lower than the predetermined value, and setting a refresh rate of the j-th row in the displayed content to a second refresh rate if at least one pixel grayscale value of the pixels in the j-th row is not lower than a predetermined value. The first refresh rate is lower than the second.
Abstract:
An LCD panel, a terminal device and a photo-sensing control method are provided. The LCD panel includes: a backlight source, an array substrate disposed on the backlight source; a photosensitive device array disposed on the array substrate; and a control circuit coupled to the photosensitive device array. By disposing the photosensitive device array on the array substrate of the LCD panel, a front panel of the terminal device is not required to be divided into multiple regions. Therefore, the camera function can be integrated into the LCD panel, and only the LCD panel is needed in the front panel of the terminal device which has both the display function and the camera function. The integration and appearance of the front panel of the terminal device is thus improved.
Abstract:
