Abstract
A video wall control device is provided in which a data processor is configured to determine a backlight control signal controlling an intensity of light supplied by at least one backlight unit among a plurality of backlight units based on image data obtained by capturing an image of a video wall device including a plurality of display panels and the plurality of backlight units supplying the light to each of the plurality of display panels, and signal transmission and reception circuitry configured to transmit the backlight control signal to the video wall device.
Claims14
A video wall control device, comprising:
- a data processor configured to obtain image data acquired by capturing an image of a video wall device including a plurality of display panels and a plurality of backlight units supplying light to each of the plurality of display panels, obtain a plurality of initial luminances, which are respective luminances of the plurality of display panels, based on the image data acquired by capturing the image of the video wall device, and determine a backlight control signal for controlling an intensity of light supplied by at least one backlight unit among the plurality of backlight units based on the plurality of the initial luminances;
- and
- signal transmission and reception circuitry configured to transmit the backlight control signal to the video wall device,
- wherein the data processor is configured to select one among the plurality of display panels as a reference display panel, and to determine one of the plurality of initial luminances corresponding to of the reference display panel as a reference luminance.
A method of controlling a video wall, the method comprising:
- obtaining image data acquired by capturing an image of a video wall device including a plurality of display panels and a plurality of backlight units supplying light to each of the plurality of display panels;
- obtaining a plurality of initial luminances, which are respective luminances of the plurality of display panels based on the image data acquired by capturing the image of the video wall device;
- selecting one among the plurality of display panels as a reference display panel;
- determining one of the plurality of initial luminances corresponding to the reference display panel as a reference luminance;
- determining a backlight control signal for controlling an intensity of light supplied by at least one backlight unit among the plurality of backlight units based on the plurality of initial luminances, and the reference luminance;
- and
- transmitting the backlight control signal to the video wall device.
