Abstract
Examples of the present disclosure relate to methods for controlling a display device. In one such example, data representing a result of an eyewear detection operation is obtained. Dependent on the obtained data, a control signal is outputted to adjust a display parameter of the display device. Performing the eyewear detection operation comprises receiving image data representing a user of the display device, and processing the image data using object recognition to determine whether or not the user is wearing eyewear of a predetermined type.
Claims17
A method of controlling a display device, the method comprising:
- obtaining data representing a result of an eyewear detection operation;
- determining a current luminance value of the display device;
- and
- dependent on the obtained data, outputting a control signal to adjust a display parameter of the display device, wherein the control signal is based at least in part on a comparison between the current luminance value and a threshold value, wherein, based on the current luminance value having a first predetermined relationship with the threshold value, the control signal is operable to adjust, as the display parameter, a first display parameter of the display device, and wherein, based on the current luminance value having a second predetermined relationship with the threshold value, the control signal is operable to adjust, as the display parameter, a second, different, display parameter of the display device,
- wherein performing the eyewear detection operation comprises:
- receiving image data representing a user of the display device;
- and
- processing the image data using object recognition to determine whether or not the user is wearing eyewear of a predetermined type.
Apparatus for controlling a display device, the apparatus comprising:
- an eyewear detector configured to obtain data representing a result of an eyewear detection operation;
- and
- a display adjuster configured to determine a current luminance value of the display device, and, dependent on the obtained data, output a control signal to adjust a display parameter of the display device, wherein the control signal is based at least in part on a comparison between the current luminance value and a threshold value, wherein, based on the current luminance value having a first predetermined relationship with the threshold value, the control signal is operable to adjust, as the display parameter, a first display parameter of the display device, and wherein, based on the current luminance value having a second predetermined relationship with the threshold value, the control signal is operable to adjust, as the display parameter, a second, different, display parameter of the display device,
- wherein performing the eyewear detection operation comprises:
- receiving image data representing a user of the display device;
- and
- processing the image data using object recognition to determine whether or not the user is wearing eyewear of a predetermined type.
