A method for enlarging a dynamic range in a digital image processing apparatus is provided to enlarge the dynamic range stably and conveniently by performing a mode for enlargement of the dynamic range on an input image only when the mode is selected. For enlarging a dynamic range of a ...
今天来捋一捋第二捆概念们——Sample rate / Bit depth / Dynamic range / Bit rate,它们影响了声音的分辨率。 图像的分辨率是大家比较熟悉的概念。在一个固定尺寸的图像里包含多少像素,决定了图像的分辨率。 image 由此可以类比声音的「分辨率」。 一个声音信号的质量由两个变量决定:采样速率 Sample rate 和 比...
Dynamic range describes the ratio between the brightest and darkest parts of an image. Learn more about HDR photography and videography today.
You may have also heard it in the context ofphotographic film, which is in itself just like a digital camera sensor that records luminance values. A particular variety of film might be capable of detecting a certain range of luminance values, like 10 or 13 stops of light. A stop of light...

But whereas human eyes can adapt to very different brightness levels, most cameras and computer monitors can reproduce only a fixed dynamic range. Photographers, motion picture artists, and others working with digital images must be selective about what’s important in a scene because they are ...
Purpose: The clinical usefulness of an advanced image-processing system called ''dynamic range control processing'' was investigated, with which selected parts of the dynamic range of digital chest images could be controlled. Material and Methods: A comparative study of 3 different post-processed for...
The dynamic range of a digital imaging device, such as a digital camera, is the ratio between the largest amount of light that the device can capture without light saturation, and the lowest amount of light the device can accurately measure and distinguish from intrinsic image noise (electrical...
The digital image processing technique was applied to dynamic displacement measurement in truss-beam local failure test.In the structural model test,light spots were labelled on measuring points and high-contrast ratio background were arranged,then images were collected by high definition camera and ide...
This paper presents a novel dynamic range compression method for digital video cameras. The proposed algorithm is designed to preserve a local image contrast based on a luminance ratio of a pixel to its local surround in attention. In general, digital video cameras are required to maintain the ...
