Abstract: An image containing characters and lines, which is inputted by a scanner or the like, is binarized and stored in a memory. A thickening process is repeatedly applied on groups of significant bits stored in the memory, until a predetermined condition is fulfilled. After this process, the thickened image is thinned at least a greater number of times than the number of times the thickening process is repeated in order to eliminate lines. As a result, characters are determined to exist at areas where groups composed of remaining significant dots exist, then characters are separated from the input image based on the areas of groups composed of the remaining significant dots.

Abstract: A method and apparatus for analyzing handwritten characters include inputting a handwritten character, recognizing the handwritten character, and extracting feature data of the handwritten character. The extracted feature data is compared with and identified to prestored feature data in memory. The prestored feature data is stored with respective handwritten character analysis data. In the case that the extracted feature data has been identified, respective handwritten character analysis data is output. On the other hand, in the case that the extracted feature data has not been identified, a message is output.

Abstract: An image processing apparatus which eliminates influence of motion of background and performs stable text-image cutout at a high extraction rate. In the apparatus, a block divider 20 divides image data in frame units into blocks of a predetermined size. A DCT unit 24 performs orthogonal transformation on each divided block, and a harmonic coefficient calculator 25 extracts data for judging whether or not the block is a character area. A still-block detector 26 compares the data with data of a corresponding block after orthogonal transformation in a previous frame, judges whether or not the difference between these data is small or large, and outputs the result of judgment. An attribute judgment unit 23 judges whether or not the block is a character area, based on the data from the harmonic coefficient calculator 25 and the data from the still-block detector 26, and outputs the result of judgment.

Abstract: An information processing apparatus, which operates in a multi-task mode, calculates a total consumption power of devices used by each task, and assigns higher execution priority to a task which uses a device with the largest consumption power, thereby shortening the execution time of the device with the largest consumption power, and suppressing the total consumption power of the apparatus. When a device is started upon switching of tasks, if the total consumption power exceeds the allowable power of the apparatus by a power consumed upon restarting of the device, the task is set in a waiting state until operations of other devices are completed, the consumption power is lowered, and it is ready to use the device by the task.

Abstract: The invention has means for judging the characteristics of a character from a feature amount of one inputted character, thereby allowing a suitable character recognizer to be adapted to the input character in accordance with the feature amount of the input character. According to the invention, since the means for judging the characteristics of a character in accordance with the feature amount of the inputted character, a size of input character is not limited. Each suitable recognizer is naturally selected in accordance with the feature amount of the inputted character. The input character can be more accurately recognized.

Abstract: According to the invention, when an image is drawn, a check is made to see if the image is overwritten onto an image which has already been inputted and displayed, thereby switching. For this purpose, a color of the image to be drawn and a color of the image which has already been inputted are compared and the image of the color of a higher priority is displayed. According to the invention, there is no need to reset a display priority of the image by a manual operation of the operator in consideration of the priority of the image. When the image is inputted, the priority of the image can be simultaneously decided. As targets to which the invention is applied, there are an image inputted by a hand-writing, an image inputted by a scanner, a character pattern which is generated from a character generator, and the like.

Abstract: Handwritten/input stroke data is compared with a gesture dictionary. If the data coincides with a specific gesture, it is checked whether the gesture is completed, and the stroke data is stored. After the meaning of the gesture command is analyzed by using the gesture dictionary, an image stroke data group which does not coincide with any gesture, and an icon group replacing stroke data which coincides with a gesture appears on the display screen. In this state, when the user taps icons having functions as gestures he/she wants to execute, the corresponding gesture commands are executed.

Abstract: In the present invention, an input handwritten character pattern is subjected to character recognition processing, and a recognition reliability of the character as a standard characteristic feature pattern is determined from the recognition result. If the recognition reliability is low, a warning is issued. In response to the warning, a user or operator can decide whether the character pattern should be registered in the user dictionary (106). If it is decided that the character pattern should be registered in the user dictionary, the character pattern is stored in the user dictionary with the information representing that the character pattern has low recognition reliability. When character patterns registered in the user dictionary are displayed on a screen, these characters are displayed in such a manner that it is possible to distinguish characters having low recognition reliability from characters having high recognition reliability.

Abstract: A character recognition apparatus and method for recognizing an unknown character by comparing strokes of the input character with stroke information stored in a dictionary. Each stroke of the input character is classified into one of plural categories according to stroke direction. The classified input strokes are rearranged into groups of strokes having the same classification. The degree of analogy between rearranged input strokes and stroke information stored in the dictionary for each group of similarly classified stroke group is calculated based on stroke length, and a maximum analogous element for each input stroke according to the calculated degree of analogy is detected. The detected maximum analogous elements are summed together, and the character whose sum is maximum is output as the identity of the unknown input character.

Abstract: Character recognition method and apparatus according to the present invention comprises the partial pattern dictionary which classifies and registers partial patterns of characters to be recognized in accordance with direction data of strokes and the partial pattern composition dictionary which classifies and registers dictionary characters in accordance with the partial patterns. When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.
