<P>PROBLEM TO BE SOLVED: To provide an electronic writing tool and the like, capable of acquiring information from a code image such as a bar code by enabling image composition in reading of the code image. <P>SOLUTION: In a code image reading mode, generally, since a reading area (imaging area or cutting area) is set slightly wide (refer to (a)), or since reading is performed from a number of light receiving elements of an infrared CMOS 614, the frame rate is low. As a result, a point where reading of a bar code cannot be performed due to missing of a read image even if the reading is tried may be caused. In a bar code reading mode, the number of light receiving elements which perform reading of pixel signal is reduced as shown in (b) to improve the frame rate. That is, an area for performing the reading of pixel signal is reduced to improve the frame rate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
