CPC Class H04N

A set of cameras can operate in coordination for surveillance purposes to provide situation awareness at a system level. Any infrastructure of cameras, public or private, can incidentally view and record an individual's mobile property when in view of any of these cameras. A locating unit can determine the approximate location of a mobile property. A monitoring device that correlates to the mobile property's location can be selected. The transmission of surveillance information from the selected monitoring device can be provided to a user, such as via a transmission to the user's mobile device. Thus, the individual can have access to the monitoring device's viewing or recorded data to increase surveillance of mobile property.

A display apparatus including a display which displays content, a communicator configured to communicate with a remote controller and an external device, and a controller. The controller being configured to, upon receiving a control command from the external device, control operation of the display apparatus based on the received control command, control the received control command to be transmitted to the remote controller, and control the communicator to transmit the received control command to the external device through the remote controller.

The present disclosure relates to a driving method and a driving device of display panels. The driving method includes: obtaining three-color sub-pixel data of each of pixels of a current image; obtaining a saturation value and a Chroma value corresponding to each of the pixels; determining if the saturation value corresponding to each of the pixels is within a predetermined range; obtaining a white-grayscale-added value in accordance with the Chroma value corresponding to the pixel, adopting the white-grayscale-added value as a white grayscale value of the four-color sub-pixel data corresponding to the pixel, and outputting the white grayscale value to the display panel upon determining the saturation value corresponding to the pixel is within the predetermined range. In this way, the brightness of the pure-color image displayed on the display panel may be enhanced, and there is no darker issue when the pure-color image is displayed.

Provided is a display device or the like which can illuminate a subject with high-luminance illumination light. Another embodiment of the present invention provides a display device which can be used as a light source for a subject, or a display device which can be used as a light source for a subject, can display images and texts, and can switch these functions. The transistor of the light-emitting device is configured to operate in a saturation region in a period during which the light-emitting device displays text or an image, and is configured to operate in a linear region in a period during which the light-emitting device emits illumination light to a subject.
