影像对比加强的装置及方法
摘要：
本发明涉及一种影像对比加强的装置，包括：亮度定义转换装置，接收第一亮度信号、第一彩度信号以及第二彩度信号以输出第二亮度信号；亮度对比调整装置，接收该第二亮度信号以输出第三亮度信号；以及亮度及色彩补偿装置，接收该第一亮度信号、该第一彩度信号、该第二彩度信号、该第二亮度信号以及该第三亮度信号以输出第四亮度信号、第三彩度信号以及第四彩度信号。本发明定义出包含彩度加权值的亮度信号，而此新定义的亮度信号经长条统计图抽取以及亮度曲线处理前后的比例关系即可用以作为显示影像原本亮度信号以及彩度信号补偿时的参数，因此，处理后的显示影像其画面具有较佳的饱和度，更符合观看者所需。
摘要（英）：

This invention relates to one image comparison strengthening device, which comprises the following parts: brightness definition conversion device to receive first brightness signal and first and second color signals to output second brightness signals; brightness comparison adjusting device to receive the second brightness signal to output third brightness signal; brightness and color compensation device to receive first brightness signal, first and second color signals, second brightness signal and third bright signal to output fourth brightness signal, third and fourth color signal. This invention defines the brightness signal with weight value through long bar statistics and brightness curve to process the proportion relationship as image original brightness signal parameters.
