Scanned image information dissolution raising method, involves moving line sensor in longitudinal direction of sensor row offset to position of line sensor during passage relative to object in scanning device

摘要

The method involves detecting an object (3) to be scanned by a line sensor (1) in relation with a movable object such that the sensor detects line-by-line images (4) of the objects at a constant scanning speed (V). The images of the objects are detected in a scanning direction transverse to a sensor row (8) of the sensor during the reduction of another scanning speed at a fractional amount of the former scanning speed. The sensor is moved in a longitudinal direction of the sensor row offset to a position of the sensor during passage relative to the object in a scanning device (7). An independent claim is also included for a device for raising release of scanned image information by using a line sensor, comprising a projection lens.
