1. A character recognition device comprising: an acceleration sensor which senses at least two axes; an acquisition section which acquires a measurement result from the acceleration sensor which is based on an operation for writing a character performed by a housing of the character recognition device while being moved in a plane, as acceleration data of a component associated with each axis; a determination section which determines a start of writing and an end of writing of one character based on the acceleration data of each component acquired by the acquisition section; an identification section which identifies, with the acceleration data of each component sequentially acquired by the acquisition section during a period from when the start of the writing of one character is determined to when the end of the writing of the character is determined by the determination section as a series of acceleration data that are temporally continuous from a first stroke to a last stroke of the character including acceleration between strokes, a plurality of feature points that exist in the series of acceleration data for each component; a generation section which generates feature point data for each component including the plurality of feature points identified by the identification section, as inputted character data; and a character recognition section which performs character recognition by collating basic character data, which has been prepared in advance for use in the character recognition, including a plurality of feature points for each component, and the inputted character data generated by the generation section.
