摘要： Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback or for generating filtered video metadata. Given an input video stream and associated metadata values of minimum, average, or maximum luminance values of the video frames in the video stream, values of a function of the frame min, mid, or max luminance values are filtered using a temporal filter to generate a filtered output value for each frame. At least one filtering coefficient of the temporal filter is adapted based on a logistic function controlled by slope and sensitivity values. The instantaneous dynamic range of a target display is determined based on the filtered metadata values and the minimum and maximum brightness values of the display.

摘要： The present invention makes possible video expressions with increased feeling of brightness and increased contrast feeling and to be able to prevent the feeling of brightness and the contrast feeling from becoming unnatural during execution of the multi-screen display. This video display device comprises: a control portion (a signal processing portion (1); an area-active-control/luminance-stretch-portion (4)) that controls a displaying portion (8) and a backlight portion (6); and a display instruction detection portion (13a) that detects display instructions of first and second input video signals. The control portion stretches and increases the luminance of the backlight portion (6), and also controls a light emitting portion enhancement processing according to a result of the detection. In the light emitting portion enhancement processing, the display luminance of a light emitting portion is enhanced by producing a histogram by integrating number of pixels for a predetermined feature amount relating to the brightness of the input video signal, detecting an upper region of a predetermined range of the histogram as the light emitting portion, and reducing luminance of a video signal of non-light emitting portion except the light emitting portion of the input video signal.

摘要： A method may involve obtaining a desired emitted brightness value for a brightness module or a display module implementable in a display device. The desired emitted brightness value may be between a first configured emitted brightness value and a second configured emitted brightness value of a plurality of configured emitted brightness values outputable by the brightness module. The second configured emitted brightness value may be higher than the first configured emitted brightness value. The method may also involve determining one of the first configured emitted brightness value and the second configured emitted brightness value to be an actual emitted brightness value outputted by the display module or the brightness module. The method may further involve determining a gain for adjusting brightness of an image content outputted by the display module to compensate a difference between the desired emitted brightness value and the actual emitted brightness value.

摘要： The image processing device includes a luminance modulator, a backlight control gain adjustment unit, a peak value detector, and a histogram detector. The peak value detector calculates a peak value as a maximum luminance value in a prescribed region of the video input signal inputted. The histogram detector calculates frequency distribution about the luminance value of the video input signal. Based on the peak value calculated by the peak value detector and the frequency distribution calculated by the histogram detector, the luminance modulator converts a luminance value of the video input signal into a luminance value of the video output signal and outputs the video output signal, for every pixel. The backlight control gain adjustment unit creates the backlight control signal based on the peak value.

摘要： A display apparatus and a brightness adjusting method thereof are provided. The display apparatus includes a panel unit which displays an image signal, a backlight unit which provides a light to the panel unit to visualize the image signal, a luminance value regulator which calculates representative values to be applied for adjusting a brightness of a plurality of partial areas of the backlight unit corresponding to the input image signal, a contrast enhancer which compensates for a brightness of the image signal compromised by the representative value through a contrast enhancement, and a pixel value compensator which compensates for pixel values of the image signal compensated using the contrast enhancement. Accordingly, the contrast ratio of the entire image can be enhanced by compensating for the brightness loss of the image signal caused from the brightness adjustment of the luminous element, and the image quality can be more finely improved.
