[31] [32] The CCDs are refreshed periodically to eliminate low-pass filtering at the scanner's native 400 dpi, increasing vertical resolution. When scanning at lower resolutions, however, the sensor traverses the page at a faster rate, inducing a slight low-pass filter over the image (in an analog fashion) and eliminating aliasing effects on ...
An image that is 100 pixels wide may need to be 400 to 600 dots in width in the printed output; if a 100 × 100-pixel image is to be printed in a one-inch square, the printer must be capable of 400 to 600 dots per inch to reproduce the image. As such, 600 dpi (sometimes 720) is now the typical output resolution of entry-level laser printers and ...
The file size of a scan can go up to about 100 MB for a 600 dpi, 23 × 28 cm (slightly larger than A4 paper) uncompressed 24-bit image. Scanned files must be transferred and stored. Scanners can generate this volume of data in a matter of seconds, making a fast connection desirable.
The ideal pixel density (PPI) depends on the output format, output device, the intended use and artistic choice. For inkjet printers measured in DPI it is generally good practice to use half or less than the DPI to determine the PPI. For example, an image intended for a printer capable of 600 dpi could be created at 300 ppi.
Splitting a film image into three colours in a Spirit DataCine scanning machine, 2006. The front end of a motion picture film scanner is similar to a telecine.The imaging system may be either a charge-coupled device (CCD), a complementary metal–oxide–semiconductor (CMOS) or photomultipliers imaging pick up.
