These two drawbacks limit the usefulness of video image capture in print applications. A new digital camera developed by Kodak uses a standard Nikon F3 camera body that accepts all Nikon lenses. The camera converts the images directly into 24-bit digital data, at a resolution of 1024 by 1280 pixels. These digital photographs can then be loaded directly into a Macintosh computer. Affecting the Quality and Accuracy of a Scanned Images A number of issues affect the quality and accuracy of the digital file captured during a scan, including the scanner resolution, dynamic range and illumination, focusing accuracy, and recognition of black and white points.
Most desktop scanners use CCDs.
Each CCD records color information and outputs one 24-bit color value. This value makes up an individual pixel in the digital image. The higher the resolution of the scan, the greater is the number of data points recorded, and the larger the file size. Variations in dynamic range impact the quality of the scan more than simple resolution does. A scanner with a lower dynamic range records the two similar colors as the same value.
