Problem to be solved: to provide a dynamic range compression apparatus in which the luminance value is not reduced after the data compression even if there is an extreme bias in the color in the frame image. The dynamic range compressing device 14 is composed of pixels per pixel depending on...

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 algorith...

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...
image with a framing problem. flare light from the lightbox surrounding the chart will decrease the measured dynamic range. avoid this unless you want to measure the effects of flare light. the image on the right has another problem, shown in the crop on the left. strange signal processing ...
Dynamic range compression is useful for displaying and enhancing images. It is common to subtract a mask from a given image to enhance the details. The trick is how to obtain a good mask. The authors describe how an edge-preserving filter can be used to generate a mask that is smooth ove...
