摘要： PURPOSE:To recognize patterns accurately by controlling the color and the luminance, with which patterns or categories are displayed, in accordance with preliminarily measured parameters with respect to the first candidate pattern giving an answer category. CONSTITUTION:An input pattern 40a is inputted to an observing part 41, and the observing part 41 converts the input pattern 40a to an electric signal 41a. This electric signal 41a is subjected to preprocessing or/and segmenting in a signal processing part 42 and is conveted to a unit pattern 42a. The pattern 42a is inputted to a recognizing part 43, and the resemblance between the unit pattern 42a and each standard pattern 44a stored in an incorporating part of a dictionary part 44 is evaluated in the recognizing part 43. On the evaluation value, an answer category 43a is outputted or this output is rejected. A signal 43a or 43b resulting from these recognition is outputted to a display part 45.

摘要： PURPOSE:To perform an original scanning and a photosensitive drum scanning at the same optical system, by dividing one laser beam by a half mirror. CONSTITUTION:A beam 120 emitted from a laser 12 is deflected by a rotational mirror 13 and its optical path up to a scanning surface is corrected by a lens 14 and is divided into two by a half mirror 51. The one scans and exposes an original 21 and an reflected light from the original surface is received with a photoelectric transducer 24 to be converted to an electrical image signal. The other is modulated on the basis of the original image signal previously obtained by an electronic shutter 52, and scans and exposes a photosensitive drum 11.

摘要： PURPOSE:To prevent unread characters from omission, to accelerate correction and to improve the speed of character input operation and reliability by displaying unread character patterns in a unread character position concerned of a recognized result character string by changing its color and luminance. CONSTITUTION:A picture processing part 44 receives position information of unread characters, executes size normalization of unread character patterns, and outputs them to a color information adder 47, which adds a color code different from that of a character generating part 46 with respect to the normalized unread character pattern and outputs it to a synthesizing part 48. In accordance with an address signal generated by a control part 52, the synthesizing part 48 outputs 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 including unread patterns is converted into a video signal in a video memory 49 and impressed on a CRT display part 50.

摘要： PURPOSE:To attain picture filing by coding automatically a key word existing at an optional position in a document descibedon a document through character recognition and adding the keyword automatically to an optional form. CONSTITUTION:A character string of an underlined part of picture information processed by a picture processing section 23 is extracted one by one character by a recognition object character extracting section 4. When a red underline is detected, the character for the part is extracted and read by using a means ANDing an underline detection signal and a character detection signal. A character recognizing section 25 recognizes an extracted character string one by one and converts it into an internal code. A code train 251 and picture processed picture information 252 obtained in this way are inputted to a file production processing section 26. The file production processing section 26 adds a retrieval keyword code 251 to the picture processed picture information 252 in a prescribed format to form a picture file data 27.

摘要： PURPOSE:To obtain a dictionary for recognition consisting of groups of the standard pattern optimum to each user by storing the information showing the change of category names of the standard patterns into said dictionary. CONSTITUTION:A feature pattern of input character is compared with a standard pattern of a memory 9 for recognition at a recognizing part 8. For the loading operation to a memory 9, a personal information dictionary is loaded to a memory 11 from an external memory 10 at first. The personal information dictionary contains a flag which decides whether this dictionary is used for each standard pattern, a flag which decides whether the category name is rewritten, and the information showing the category name of the other side if the category name is rewritten. When the loading is through with the personal dictionary, the standard patterns of a recognition dictionary are loaded successively. Each standard pattern is loaded to the memory 9 in case the pattern is used with reference to the corresponding flag of the personal dictionary and also used with rewriting of the category name. In the case of the latter, the category name is changed and loaded. The loading operation are through when the above-mentioned operation is carried out with all standard patterns.

摘要： PURPOSE: To prevent the continuation of rejection and reading error by measuring the rejection ratio of one business form and switching a deciding parameter.
CONSTITUTION: An area including a character pattern drawn in an input business form 1 is converted into a binary pattern by a photoelectric conversion part 2 and the binary pattern is supplied to a preprocessing part 3. The preprocessing part 3 segments only one character from the business form image expressed as the binary pattern and sends the segmented character to a buffer memory 4. The character pattern stored in the buffer memory 4 is processed by a feature extracting part 5 and the extracted characteristic variable is stored in a buffer memory 6. On the other hand, a category name and a characteristic variable for a previously fixed standard pattern are found out and stored in the dictionary 7. The contents stored in the buffer memory 6 are successively collated with the contents read out from the dictionary 7 and the collated result is sent to a discrimination part 9. The output of the deciding part 9 is sent to a post-processing part 10 and the insertion of the rejected character or the like is executed.

摘要： PURPOSE:To use a slip with free format without reference mark, by overlapping the range of the photoelectric conversion of a one-dimension photoelectric converter for a size for one character's share or a one line's share of pitch or over. CONSTITUTION:The slip is stopped with a paper feed mechanism when the slip is moved toward the Y direction by a distance for one line or one character or over less than the range read with a sensor in the photoelectric conversion section 50. The image converted into an electric signal with the sensor is converted into a digital signal at an A/D converter 51 and stored in a video memory 52. A character recognizing section 53 reads out the image of the video memory 52 for attaining character recognition.

摘要： PURPOSE:To obtain efficiently the output having no variance, by attaching photoelectric transducers, which are long in the direction orthogonal to the movement direction of an object face, near the moving object face and scanning a light spot in the longitudinal direction of photoelectric transducers and converting photoelectrically reflected lights. CONSTITUTION:The laser light from a laser light source 5 is condensed by a lens 9 to irradiate a rotary polyhedral mirror 6. The laser light reflected by the rotary polyhedral mirror moves in the x-axis direction to scan an object 4 moving in the y-axis direction, and the optical path length difference generated in this case is corrected by a correcting lens such as an Ftheta lens. Photoelectric transducers 81 and 82 which are long in the x-axis direction are arranged near the object 4. Photoelectric conversion faces 811 and 821 are coupled with respective anodes 812 and 822 to receive the reflected light from the object 4. Thus, a high-resolution output having no variance is obtained efficiently with a simple device. If the device is stored in a case, to which the external light is not incident, to improves S/N or a light scattering medium which prevents the abnormal output due to the specular reflection is used, the better result is obtained.
