摘要： For obtaining an good yet easy to use luminance dynamic range conversion, we describe an HDR video decoder (250) comprising an image color processing apparatus (200) arranged to transform an input color (Y'UV_LDR) of a pixel of an input image (Im_in), which input image has a first luminance dynamic range (DR_1), into a red, green and blue color component output color (R'o, G'o, B'o) of a pixel of an output image (Im_res; REC_HDR), which output image has a second luminance dynamic range (DR_2), whereby the peak luminance of the first dynamic range is at least 2 times lower than the peak luminance of the second dynamic range or vice versa, comprising a coarse mapping unit (202; 552) arranged to apply a three-segment brightness re-grading curve which consists of a linear segment for a dark sub-range (SR_d) of the range of lumas of the input image colors comprising the darkest input luma values, which is determined by a slope variable (InvBet), a second linear segment for the lightest input luma values in a bright sub-range (SR_br), which is controlled by a second slope variable (InvAlph), and a parabolic segment in between the two linear segment.

摘要： A video display control device includes a video signal processing section 112 that corrects a video signal based on control data generated by a control data generating section 131 and outputs a video signal after correction to a display 12, and a backlight controlling section 14 that controls a light emission luminance of a backlight 122 based on a difference between a mean luminance of the video signal and a means luminance of the video signal after the correction. The control data generating section 131 allocates a part of a dynamic range of a high gradation region of a video signal to a low gradation region. The backlight controlling section 14 controls a light emission luminance of the backlight 122 so as to cancel an increase or decrease of a mean luminance of a video to be displayed on a screen 121 in accordance with an increase or decrease of the mean luminance of the video signal after the correction with respect to the mean luminance of the video signal. Consequently, even when an amplitude of the video signal is equal to a width of the dynamic range, it is possible to achieve improvement of a contrast and reduction of consumption power.
摘要翻译：视频显示控制装置包括：视频信号处理部分112，其根据由控制数据产生部分131产生的控制数据校正视频信号，并将校正后的视频信号输出到显示器12;以及背光控制部分14，基于视频信号的平均亮度与校正后的视频信号的装置亮度之差的背光源122的发光亮度。控制数据生成部131将视频信号的高灰度区域的动态范围的一部分分配给低灰度区域。背光控制部分14控制背光源122的发光亮度，以便根据视频的平均亮度的增加或减小来取消要在屏幕121上显示的视频的平均亮度的增加或减小相对于视频信号的平均亮度进行校正后的信号。因此，即使当视频信号的幅度等于动态范围的宽度时，也可以实现对比度的提高和消耗功率的降低。
