I.介绍 数字视频摄像机通常具有捕获具有约200%至600%亮度水平的高动态范围(high dynamic range, HDR)图像的能力,而大多数显示设备具有仅具有约110%亮度水平的低动态范围(low dynamic range, LDR)。因此,动态范围压缩技术对于显示由数字视频摄像机捕获的图像是必不可少的。在许多情况下,通过动态范围压缩来保持阴影到...
A method and apparatus for processing image data is described, comprising acquiring a frame of image data and compressing the dynamic range of the frame of image data using a dynamic range compression (DRC) algorithm that utilizes down-sampling, median filtering, and up-sampling. The DRC ...

The curve is smoothed using a rectangular kernel 7 points wide (approximately 1/14 of the total range). This algorithm gives better results than earlier (pre-4.4) Patch range and detected DR measurements. Slope-based Dynamic Range it is NOT recommended because SNR can be extremely low (often...
下周正式开搞AEC,把之前做的一些事情记录一下。 https://en.wikipedia.org/wiki/Dynamic_range_compression Downward compressionreduces loud sounds over a certain threshold while quiet sounds remain unaffected.Upward compressionincreases the loudness of sounds below a threshold while leaving louder passages unch...
