Method for operating an optical sensor, particularly a code reader and a code reader

摘要

The optical sensor receives reflected or remitted light and generates a corresponding image whose content is read. At least some images are compressed in the sensor using a compression algorithm. The method involves compressing and storing only images corresponding to a faulty reading. The compressed images contain an objector code to be read and an object environment AN Independent claim is also included for the following: (a) a code reader.
