Abstract

According to one embodiment, a code reading apparatus comprises an image pickup unit, a light source, a reading unit and a light source control unit. The image pickup unit configured to image pickup a commodity placed in a image pickup area. The light source configured to irradiate pulsed light towards the image pickup area. The reading unit configured to read the information related to the commodity from the image picked-up by the image pickup unit. The light source control unit configured to increase the pulse width of the pulsed light gradually until the quantity of light reaches a level at which the reading unit can read the information when the light source is turned on, and decrease the pulse width of the pulsed light gradually until the quantity of light becomes 0 when the light source is extinguished.

Description

[0001] This application claims the priority of the Japanese applications with the application date of May 13, 2011, application number JP2011-108648 and the application date of February 23, 2012, application number JP2012-037866, and cites the contents of the above applications. technical field [0002] The invention relates to a code reading device and a code reading method. Background technique [0003] At present, in shops such as supermarkets, a code symbol reading device is used, and the image of the code symbol is captured by an area image sensor such as a CCD (Charge Coupled Device Image Sensor) imaging element, and sent to the POS (PointOf Sales: point of sale) Terminals, etc. output commodity codes. In such a code symbol reading device, a light source such as an LED (Light Emitting Diode: Light Emitting Diode) is pulsed to illuminate a product or a code symbol, etc., thereby ensuring the amount of light required for imaging. Then, imaging by the imaging element is ...
