A selection apparatus capable of efficiently selecting an optimum setting condition for filtering is provided. The selection apparatus is an apparatus that selects a setting condition for filtering to be performed on a reading target. The selection apparatus includes: a determiner that determines whether the reading target is readable with each of a plurality of combinations selected from among combinations of all setting conditions for at least two types of filtering; and a selector that selects a setting condition for the filtering based on a result of the determination by the determiner.

Selection apparatus and selection method

An optical code reading process and a reading stability determining process are performed while suppressing an increase in the cost of a transfer system and avoiding a decrease in work efficiency. CMOS performs imaging. Processor reads an optical code contained in image data taken by CMOS and outputs a signal upon success of reading of the optical code. Further, processor calculates a first contrast at the time of teaching and a second contrast at the time of reading success, and determines reading stability based on a decrease rate of the second contrast with respect to the first contrast.
