Image scanning device and method for controlling scanner output

A method for generating a quality scan by predicting scanner lamp output whenever a scanner operation is initialized. Lamp output is measured within a duration after powering on the lamp and prior to a point at which maximum lamp output is reached. The lamp output for the remaining duration of the s...

Zusammenfassung:A method for generating a quality scan by predicting scanner lamp output whenever a scanner operation is initialized. Lamp output is measured within a duration after powering on the lamp and prior to a point at which maximum lamp output is reached. The lamp output for the remaining duration of the scanning operation is predicted based on these lamp output measurements, a threshold value and the maximum lamp output. The gain of the scanner output control device is adjusted to compensate for the predicted lamp output to produce quality scan.
