Abstract
A data input system is provided with an input pen. A sequence of characters are traced with the input pen, and image data on them are read from the image scanner incorporated in the input pen. Each character is recognized on the basis of the image data. If a recognition error occurs during the input processing, a correct character is written with the input pen. A locus of movement is traced on the basis of moving distance data, which is obtained by a moving distance sensor and includes a moving distance and a moving direction. A character represented by the traced locus is recognized.
Claims13
A data input system which comprises a main apparatus and an input pen externally connected to the main apparatus, and which inputs data in accordance with a manner in which the input pen is operated,
- said input pen having:
- an image scanner;
- and
- a moving distance sensor, and
- said main apparatus including:
- first character recognition means for cutting out a character region from image data read by the image scanner of the input pen, and for executing character recognition;
- correction-required character specifying means for specifying a character from among a sequence of characters recognized by the first character recognition means;
- second character recognition means for tracing a locus of movement based on moving distance data, which is obtained by the moving distance sensor of the input pen and includes a moving distance and a moving direction, and for recognizing a character written with the input pen based on the traced locus of movement;
- and
- recognized character correcting means for replacing a character recognized by the first character recognizing means and specified as a correction-required character by the correction-required character specifying means with a character recognized by the second character recognition means.
A data input system which comprises a main apparatus and an input pen externally connected to the main apparatus, and which inputs data in accordance with a manner in which the input pen is operated,
- said input pen having:
- an image scanner;
- and
- a moving distance sensor, and
- said main apparatus including:
- first character recognition means for cutting out a character region from image data read by the image scanner of the input pen, and for executing character recognition;
- second character recognition means for tracing a locus movement based on moving distance data, which is obtained by the moving distance sensor of the input pen and includes a moving distance and a moving direction, and for recognizing a character written with the input pen based on the traced locus of movement;
- and
- distinguishing means for automatically distinguishing among newly input data provided by the first character recognition means, corrected input data provided by the first character recognition means, newly input data provided by the second character recognition means, and corrected input data provided by the second character recognition means, in accordance with a manner in which the input pen is operated.
