摘要： PURPOSE:To prevent unread characters from ommision, to discover erroneously readout characters and to accelerate the correction by displaying an original character pattern near corresponding recognized characters by changing its color and luminance. CONSTITUTION:A picture processing part 44 receives position information of unread characters from a control part 52, and executes size normalization of a character pattern so that character pattern image 32 can be embedded near a corresponding recognized result characters 31. Character position information of normalized unread characters is outputted to a color information adder 47, which adds a color code different from that of a character generator 46 with respect to a character pattern image, and outputs it to a synthesizing part 48. In accordance with an address signal generated by the control part 52, the synthesizing part 48 transmits two types of image information of the color information adder 47 and the character generating part 46 to a video memory 49. A recognized result character string arranged near character patterns is converted into a video signal and impressed on a CRT display part 50.

摘要： PURPOSE:To reduce the capacity of a memory for information preservation to perform the retrieval easily with a keyword, by encoding only a required part of documents with the keyword and eliminating redundant information to compress information. CONSTITUTION:An objective document 10 is converted to an electric signal by a scanner 22, and noise or the like in the signal is eliminated by a preprocessing 23 and the resulted signal is preserved in a buffer memory 24. Contents of the memory 24 are read out successively to a recognizing part 25 and are encoded to characters and are preserved in a memory 20. A segmenting part 26 obtains a histogram in the horizontal direction of the read image to segment a block. The output of the recognizing part 25 is collated with the keyword inputted from an input part 27 by a collating part 28; and if they coincide with each other, a coincidence signal is outputted to a decision part 29. The decision part 29 obtains block information for generation of the coincidence signal from the segmenting part 26 and reads a required code from the memory 20 to obtain a result in an output A. Thus, the capacity of the memory is reduced to facilitate retrieval.

摘要： PURPOSE:To eliminate the rearrangement of matching results and to attain a high-speed processing by storing the category name of a feature used for matching to the address groups of an RAM decided by the distance value between the features. CONSTITUTION:The address of the RAM is designated by the matching result l, and the category name of a standard pattern is stored to the RAM address. In this case, plural same distances or their approximate values are obtained and therefore category groups G1, G2... are provided to set the most significant bit at 0 for the address storing the category names. Thus the RAM stores the categories in the order of small size of l and the RAM addresses are successively changed and the contents of the RAM are read out. Thus both category name and distance can be obtained. When the most significant bit is set at 1, the RAM changed to the address storing the category groups. Thus it is possible to read out only a desired part at a high speed.

摘要： PURPOSE: To avoid the regular reflection and to improve the intensity of illumination, by illuminating a surface to be irradiated with a planar light source which is formed with the luminous flux given from a light beam radiating aperture part and at the same time providing a diffusing/reflecting surface at the opposite side to the light source centering on a normal line of the surface to be irradiated and approximately in parallel to the normal line.
CONSTITUTION: A point P on a surface 62 to be irradiated is illuminated by a planar light source 61 like a fluorescent lamp having an aperture part ML. A diffusing/reflecting surface 63 is set at the side opposite to the light source 61 centering on a normal line PQ at the point P and approximately in parallel to the line PQ. Then the point P is irradiated by the diffused and reflected light. An angle ϕ formed by an end M of the part ML and the line PQ is set larger than an incident angle obtained when the regular reflection is produced at the point P. In addition, it is avoided for the outer tube of the fluorescent lamp 61 to come over the luminous flux SS' of the reflected light at the point P. The regular reflection is produced at a small recess on the paper due to a ball pen, etc. This improves the luminous intensity at the point P, and at the same time the regular reflection is avoided at the point P to ensure an accurate photoelectric conversion.

摘要： PURPOSE:To realize the recognition of a pattern with high accuracy and in a small number of standard patterns, by deciding whether or not the preprocess carried out to an unknown pattern is suited to the rule of a standard pattern and inspecting the rightfulness of the result of evaluation. CONSTITUTION:An unknown character pattern 10 is supplied to a pattern matching part 500 via an observing part 100, a thickness process part 200, a structure analyszing part 300 and a feature extracting part 400 each. Then the resemblance is evaluated between the feature quantity of the output at the part 400 and each dictionary item showing the character conception within a dictionary 900. Then a rightfulness inspecting part 600 supplies the parameter 20 sent from the parts 100, 200 and 300 each plus a pair 15 of the dictionary item number and the distance to inspect the rightfulness to each dictionary item by referring to an inhibition rule table 1,000. Thus a pair of the dictionary item number and the distance having the rejected rightfulness is disused, and only the residual pair is turned into an output 16. Then a strategy deciding part 700 has the final decision or a retrial of the recognizing process.

摘要： PURPOSE:To facilitate an easy production of format information and also to simplify a pattern reading system as whole, by estimating the format information on the paper surface from the image information stored in a memory and recognizing a pattern on the paper surface based on said format information. CONSTITUTION:The image of a form 1 is scanned by a photoelectric transducer 2 and stored to a buffer memory 3 as the digital pattern information. The pattern information in the memory 3 is processed by a format information estimating part 4. Thus the format information is produced and stored to a buffer memory 5. The pattern information of the memory 3 is added to a segmenting part 6 together with the format information of the memory 5. The part 6 segments a character pattern on the paper by a known method. The segmented character pattern is recognized by a recognizing part 7, and the result of this recognition is sent to an output device 8. It is more convenient to read the format information into the memory 5 from an external memory 9 and to use the format information produced previously.

摘要： PURPOSE:To improve a pattern compressing ratio to about 1/100 so that a two- dimensional pattern can be compressed, by encoding the recognized result of the two-dimensional pattern after positional information is added to the result. CONSTITUTION:Information of a document 1 is converted into an electric signal by means of a scanner 2 and the electric signal is sent to a cutting section 3. The cutting section 3 detects character parts from the electric signal and sends the character parts to a character pattern recognizing section 4 and, at the same time, supplies positional information of the stubbed characters, such as position, size, etc., to an encoding section 5. Moreover, a recognized result code from the recognizing section 4 is also sent to the encoding section 5 where the recognised result code is encoded and code information of one character is obtained. The code information is given to a storage device 6. By having a character code together with information of a two-dimensional plane, a two-dimensional pattern can be reproduced in the form of a fair copy.

摘要： PURPOSE: To attain an input even for the Chinese characters with which both sound reading and Japanese rendering are impossible, by selecting the candidate characters based on the information on the radicals, the number of strokes, etc. of input characters and then displaying them.
CONSTITUTION: When reading is impossible with an input Chinese character, an operator feeds the number of strokes, for example, of the input character through a keyboard 1. In this case, the radical information such as sides, right- hand radicals, etc. can substitute the number of strokes. When receiving this input, a processor 2 gives access to a code conversion table 3 to deliver plural character codes 10 and to supply them to a character generator 5 via a sector 4. Then the generator 5 converts these character codes into character patterns and displays plural candidate character patterns to a display 6. Thus the operator decides a corresponding character pattern among those patterns displayed at the display 6 and feeds it. Thus it is possible to feed even a Chinese characrer with which both the sound reading and Japanese rendering are impossible.

摘要： PURPOSE:To shorten the correcting operation time of characters inputted through an optical character reader or the like, by watching only information displayed on a display screen to designate a correction position without key operations of the operator. CONSTITUTION:For example, Kanji (Chinese character) ''yama'' (''mountain'' in English) is displayed on a display device 14 and should be corrected. When an operator 11 sees character ''yama'', the position of the operator's eye is detected by a television camera 13. The position of his eye is converted to coordinates, and they allowed to correspond to character ''yama''. When the position of character ''yama'' is detected, a cursor is moved automatically to the position to report it to the operator. The operator inputs information to be corrected to a microphone 12. Correction information is recognized by a voice recognizing processing part of a processor 15. The processor replaces character ''yama'' with information from the operator and displays this information on the display device. Though correction information can be inputted by a keyboard, position information of his eye is prevented from being lost in this case.
