Images from modern digital cameras which produce very large (6MP or 10MP) files can look much better when slightly reduced in size. Check format Always save photographs as high quality JPEGs. If the image is made on the computer and is not a photograph, painting, or scan, it probably shouldn't be in JPEG format at all – see Preparing images ...
Making an image that was incorrectly saved as JPEG fit for saving as PNG; Suppose you have a map for an island that was inadvertently saved as JPEG. Looks OK, if a bit fuzzy. 1. In your bitmap graphics editor, set your fuzzy selection ("magic wand") tool so that it only will select pixels of exactly the same color. (Here: Threshold = 0) 2.
Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...

The most common strategy is to look for patterns or trends in the pixel values, then store a parameterized form of the pattern instead of the original data. Common raster compression algorithms include run-length encoding (RLE), JPEG, LZ (the basis for PNG and ZIP), Lempel–Ziv–Welch (LZW) (the basis for GIF), and others.

Most raw files contain a full size JPEG conversion of the image, which is used to preview the file on the camera's LCD panel. In the case of motion picture film scans, either the timecode, keycode or frame number in the file sequence which represents the frame sequence in a scanned reel. This item allows the file to be ordered in a frame ...
The Muirhead had a fixed resolution of 100 lines per inch and the engineers wanted a 512×512 image, so they limited the scan to the top 5.12 inches of the picture, effectively cropping it at the subject's shoulders. The image's reach was limited in the 1970s and 80s, which is reflected in it initially only appearing in .org domains.
