A method enhances brightness in video frames of a video during streams. The method includes determining, by a processor, that a first video frame has low light. The method further includes applying, by the processor, a linear correction to provide a first brightness enhancement in the first video frame that modifies a first brightness of a predetermined darkest percentage of pixels to be less than a darkness threshold value or a second brightness of a predetermined lightest percentage of the pixels to be greater than a lightness threshold value. The method further includes averaging, by the processor, the first brightness enhancement of the first video frame with a set of brightness enhancements corresponding to previous video frames to generate a modified video.

A display device which supports a panel self refresh (“PSR”) mode includes a source unit and a synchronizing unit, and a signal is transmitted between the source unit and the synchronizing unit through an interface. The source unit determines on/off of the PSR mode in response to a PSR setting value, and additionally determines whether to activate the PSR mode in response to luminance information.

The embodiments of the disclosure relates to the technical field of projection adjustment. Embodiments specifically disclose a self-adaptive adjustment method and adjustment system for brightness of a projection apparatus. In the disclosure, ambient illuminance and a projection distance of the projection apparatus are obtained by controlling an illuminance sensor and a distance sensor, and a functional relationship among the ambient illuminance, projection plane illuminance and the projection distance is found through analysis and modeling of a large amount of data.

Embodiments of the disclosure provide a method and an apparatus for controlling brightness of a screen widget, a terminal and a storage medium. The method includes: obtaining display data; determining a widget area of the screen widget based on the display data, in which the screen widget is configured to display multimedia information in a form of a small window on the display screen; and controlling a brightness of the widget area to be adjusted to a target brightness.

The appearance of a display image of image content is made appropriate without particular user operation irrespective of viewing environment changes.

A reception unit receives image content. A processing unit performs image quality adjustment processing on the received image content on the basis of metadata for image quality adjustment depending on viewing environment information. For example, the reception unit transmits the viewing environment information to a server and receives the metadata from the server. Further, for example, a metadata generation unit configured to generate the metadata on the basis of the viewing environment information is provided.

The disclosure discloses a TV backlight control method, which includes the following operations: acquiring current first ambient brightness information and a user type in a space where a TV set is located; determining a backlight adjustment value according to the first ambient brightness information and the user type. The brightness value of the TV backlight is reduced according to the backlight adjustment value. The present disclosure further discloses a control device, a TV set and a readable storage medium.
