Abstract:
[Object] To enhance accuracy at the time of setting with consideration of a cell size of a code when an exposure time is automatically set. [Means to solve the problems] An upper limit of an exposure time of an imaging part as a restriction condition for reading a code attached to a workpiece is calculated based on a moving speed of the workpiece, which is inputted by an input part, and a cell size, which is calculated by a cell size calculation part. An exposure time of the imaging part is set within the restriction condition by analyzing a plurality of images, which includes a code and is obtained by taking images multiple times by changing the exposure time of the imaging part.

Claim (Index 18):
An optical information reading method using an optical information reading device having an imaging part including an imaging element which takes an image of a code attached to a workpiece which moves and having a characteristic information storage part storing a characteristic information which determines a visual field range of the imaging part corresponding to the distance from the imaging part to the code, the optical information reading method comprising the steps of:\n inputting a moving speed of the workpiece, a moving direction of the workpiece, and a distance from the imaging part to the code based on user operation; calculating a resolution in the inputted moving direction based on the inputted distance and a number of pixels of the imaging element in the inputted moving direction, calculating a size of a cell which constitutes the code in the image obtained by the imaging part, based on the resolution and the code included in the image obtained by the imaging part, and calculating an upper limit of an exposure time of the imaging part based on the inputted moving speed and the calculated size of the cell, the upper limit being used for tuning a condition for reading the code attached to the workpiece; setting the exposure time of the imaging part within the calculated upper limit; and decoding code included in an image, which is newly obtained by the imaging part using the set exposure time.
