T establishing a color lookup table according to equation (6), wherein input indexes of the color lookup table are the filter result and the Cr pixel values or the Cb pixel values, in YCbCr color space, of the input pixels; wherein the step of obtaining the output luminance pixel value of the first input pixel according to the luminance pixel value of the first input pixel and the transforming ratio between the function result and the filter result comprise: obtaining the output result of the first input pixel according to the luminance lookup table, the luminance pixel value of the first input pixel and the filter result; and. The tool operates in RGB space and is applied right after Noise Reduction and Haze Removal, but before other tone curve adjustments such as the Exposure controls. The dynamic range compression method as recited in, obtaining a first regularization parameter according to the filter result, an input pixels brightness maximum value, a minimum parameter, and a maximum parameter, wherein the minimum parameter and the maximum parameter are both greater than 0; and. You can, however, use this tool on the stitched panorama. You can, however, use this tool on the stitched panorama. 16 + in , Similarly, the color lookup table 522 is configured to use Cin i(x,y) (viz., the Cb pixel value 404) and the filter result Lin avg(x,y) as the input indexes, and to output the Cb output chroma pixel value of an input pixel. The effects of this tool depend on the dynamic range (and histogram) of the image being edited. avg y [ A curve gives one more control over the process, however this tool is designed specifically for the task. avg The method includes receiving a plurality of input pixels which include a first input pixel, obtaining a luminance pixel value of each of the input pixels, executing a filter execution according to the luminance pixel values of the input pixels to obtain a filter result corresponding to the first input pixel, transforming the filter result into a function result according to a function, and obtaining an output luminance pixel value of the first input pixel according to the luminance pixel value of the first input pixel and a transforming ratio between the function result and the filter result. The color lookup table 523 is configured to use Cin i(x,y) (viz., the Cr pixel value 406) and the filter result Lin avg(x,y) as the input indexes, and to output the Cr output chroma pixel value of an input pixel. An image processing device comprising: a luminance capture circuit, configured to receive a plurality of input pixels, wherein the input pixels comprise a first input pixel, and the luminance capture circuit is configured to obtain a luminance pixel value of each of the input pixels; a filter execution circuit, coupled to the luminance capture circuit, configured to execute a filter execution according to the luminance pixel values of the input pixels to obtain a filter result corresponding to the first input pixel; and. C [ - The dynamic range of an image can be compressed by replacing each pixel value with its logarithm. If you imagine an outdoor scene on a very foggy day, the brightest element would not appear much brighter from the darkest element, so the scene is said to have a low dynamic range. If you need to compress the dynamic range across a series of images in a consistent way, use a curve instead. ( $\begingroup$ "Dynamc range compression" is a good label. - This has limitations, which often become noticeable when the dynamic range of the scenery is very large, like the image in this example. ( 11. ) ( â¡ 1-4. 18 x In view of the foregoing, it is intended that the invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents. avg y To show the scene on the viewing device, generally two things can happen: either a certain segment of the dynamic range which falls outside of that which the monitor can reproduce is discarded (the sky outside is clipped white so the you can see the inside of the room, or the sky outside is reproduced at the cost of the room being clipped black), or the dynamic range of the scene can be compressed so that both the dark and the light areas are visible, and that is where this tool comes into play. â¡ ) ( [ The basic idea of our approach is to separate illumination and reflectance components of an image in the compressed domain. ( [ It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. Do not use this Dynamic Range Compression tool on the source images. w 8. out The amount of detail that is preserved can be tuned with this parameter. i The Dynamic Range Compression tool is used to compress and redistribute the dynamic range of the scene captured in a photograph. obtaining the output chroma pixel value of the first input pixel according to equation (6), 7. â¡ i The Dynamic Range Compression tool is used to compress the dynamic range of an image, reducing highlights and lifting shadows. The idea of suitably modifying the existing universal image quality index is also proposed for its participation in iteration termination, and to gauge the property of dynamic range compression. 10 Be compressed by replacing each pixel value of a measured signal other embodiments large!
