    Abstract: A system for monitoring a back light module is provided. The system includes an obtaining unit configured to obtain an intensity of output light from the back light module, a detection unit configured to detect whether the intensity of the output light from the back light module is greater than a preset value, and a control unit configured to control the back light module to reduce the intensity of the output light in response to detecting that the intensity of the output light is greater than the preset value, such that the reduced intensity of the output light is equal to or greater than the preset value.

    Abstract: The present application provides a method for adjusting backlight brightness levels of a display. A display region of the display is divided into a plurality of sub-display regions. Each sub-display region displays a sub-image region of a to-be-displayed image. A backlight brightness level of a sub-display region is adjustable. The method including: determining if white-image areas in a sub-image region satisfies a preset condition; and increasing the backlight brightness level of a sub-display region corresponding to the sub-image region if the white-image areas satisfy the preset condition.

    Abstract: The present invention provides a monitoring method and a monitoring device, belongs to the field of electronic monitoring technology, and can solve the problem that useless video data occupies storage space and key video cannot be extracted quickly when an event occurs in the existing monitoring device. The monitoring method of the present invention comprises: determining whether or not a first image is changed; generating a storage instruction if it is determined that the first image is changed; collecting and storing images of external environment according to the storage instruction; obtaining a second image according to the collected images of external environment; determining whether or not the second image is changed; and stopping storing images of external environment if it is determined that the second image is not changed.

    Abstract: An image compensation method and apparatus is provided. The method may include: determining, as the second brightness value, a brightness value for which a SAD corresponding to the brightness value and the first brightness value is the minimum, in brightness parameters of a second image displayed at a second time; determining a membership degree corresponding to a target SAD; determining a motion compensation parameter corresponding to a first coordinate and a median frame interpolation parameter corresponding to the first coordinate; determining a brightness compensation parameter corresponding to the first coordinate based on the membership degree corresponding to the target SAD, the motion compensation parameter corresponding to the first coordinate and the median frame interpolation parameter corresponding to the first coordinate; performing an image compensation so as to display a compensated image at a time between the second time and the first time based on the brightness compensation parameter corresponding to the first coordinate.
