The dynamic range compression device includes a total signal intensity circuit that calculates total intensity based on all of the signal data, a recalculation circuit that calculates a new compressed value for each signal data based on the calculation of total signal intensity to within a narrower ...
Method and image processing device for image dynamic range compression with local contrast enhancementAn image dynamic range compression with local contrast enhancement method for an image processing device is provided. The method includes the following steps. A plurality of input pixels of an image ...
Image of an HDR scene with local tone mapping Dynamic Range (DR) is the range of exposure, i.e., scene brightness, over which a camera responds with good contrast and good Signal-to-Noise Ratio (SNR). This is a scene-dependent image quality factor that incorporates sensor sensitivity, noi...
To properly compress a dynamic range by the dynamic range compression processing method which obtains a processed image signal by compressing the dynamic range of an image signal of the original image even when the contrast of the original image is different from the contrast of a normal image.收...
The pixels in modern cameras’ image sensors can capture a wide range of light, but if you shoot in a format like .wmv or .avi that results in compression, you may lose a lot of that dynamic range. “If you’re shooting raw, you have a ton of information in that image,” Duchesnea...
Exposure and Gamma Lets you manually adjust the brightness and contrast of the HDR image. Move the Exposure slider to adjust gain and the Gamma slider to adjust contrast.Highlight Compression Compresses the highlight values in the HDR image so they fall within the luminance values range of ...
Date Oct. 1, 1992.An audio signal has its dynamic range compressed by a system which first samples a block of the audio signal (10), typically several seconds long. The level of the signal in this block is analyzed (12, 14) and an ideal signal level is calculated for the block (16...

Evaluating the quality of high dynamic range (HDR) images has emerged as a challenging and contemporary topic with the proliferation of HDR content. In this work, a new HDR compression (HDRC) database is proposed, aiming to provide a benchmark for the development of full-reference HDR image ...
