Embodiment Construction

[0039] Referring to FIG. 1, there is illustrated a schematic diagram of an electronic device 100, in the form of a mobile station or mobile telephone, including a radio frequency communication unit 102 connected to and in communication with a processor 103. The mobile phone 100 also has a user interface including a screen 105 and a keypad module 106 connected to and in communication with the processor 103 . Alternatively, the user interface may take the form of a touch screen 105 . It is clear to those skilled in the art that in this alternative embodiment, the keyboard module 106 can be omitted.

[0040] The processor 103 includes an encoder / decoder 111 with an associated coded read-only memory (ROM) 112 that stores data for encoding and decoding voice or other signals that may be transmitted or received by the mobile telephone 100 . Processor 103 also includes microprocessor 113, which is connected to encoder / decoder 111, character read only memory (ROM) 114, random access ...

Abstract

The invention is a method for identifying characters by electronic equipment, comprising: obtaining a primary pixel matrix; duplicating the primary pixel matrix into plural initial spare matrixes, each of which is divided into a group of submatrixes; successively, vertical to columns of the submatrixes, selectively moving text forming pixels in the submatrixes by integral times to provide new spare matrixes, where the moving is relative to text forming pixels in a reference submatrix of each initial spare matrix and determined the approach degree of each submatrix relative to the reference submatrix; determining which of the new spare matrixes is selected; dividing the selected matrix into a segmented character matrix for character identification.

Description

technical field [0001] The present invention generally relates to methods of character recognition by electronic devices. The present invention is particularly useful, but not necessarily limited, for automatic recognition of italicized text, such as italicized text. Background technique [0002] In character recognition applications such as optical character recognition (OCR), characters to be recognized are sometimes italicized. Characters in an italic style generally include all characters slanted in one direction. [0003] Character recognition includes the process of character segmentation before character recognition can be performed. Character segmentation produces vertical segment boundaries between adjacent characters. Therefore, since a segment may contain data (pixels) from multiple characters, OCR on italic characters will result in incorrectly segmented characters if the characters are skewed out of address. [0004] One solution to the problem of performing...
