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 ...
Quality (SNR)-based Recommended in most cases. the range of exposure where the Digital Number (pixel level) is below 98% of the saturation level (250 for 8-bit systems, which have a maximum of 255), and the scene-referenced Signal-to-Noise Ratio (SNRscene) is greater than a specified...
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...
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 ...
Film cameras were developed in order to record light so that it could be reproduced on photographic paper; digital cameras so that it could be reproduced on a computer screen. Neither computer screens nor paper can display nearly the dynamic range (ratio between dark and bright regions) as what...

Film vs. Digital Digital Image File Formats Tools for Reducing Dynamic Range So What Dynamic Range Do I Need? Dynamic Range: An Example Before we start here, consider this question: Have you ever had a secret or an ‘aside’ comment that you needed to whisper to the person next to you?
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 ...
