Title: Detector for unlighted light source
Inventor: ISHIKAWA OSAMU
IPC: H04N1/04
Filed: 1987-01-12
Abstract: PURPOSE:To eliminate the need for an exclusive component for detecting unlighted light source by detecting a level of an image signal at each section obtained by dividing one line, comparing the levels of the detected section and comparing the level of the detected section with the level specified in advance. CONSTITUTION:An arithmetic circuit 15 divides a binarizing signal C of one line into n sets of sections, counts white bits at each section, judges whether or not white bits of prescribed bits or over exist at each section and informs result to a control circuit 16. The control circuit 16 judges whether the slice level B is above or under the image signal at each section, sets the slice level B to a closer level at each section, reads the next line, judges whether the slice level B is above or under the image signal and sets the slice level B to the closer level. The operation is repeated for many times to identify the characteristic of the image signal at the time of light source lighting and the image signal at the time of unlighted light source depending on the shape of the level detected at each section. Thus, the mounting of an exclusive component such as a photodetection sensor is not required.

Abstract: PURPOSE:To obtain a static convergence circuit in a 6-tube system projection receiver in which no mis-convergence is caused on the reception of an interlace signal. CONSTITUTION:This circuit is provided with a switch timing for a changeover circuit 28A applying a picture position detection pattern signal to projecting tubes 21, 22, 23, 41, 42, 43 and a switching timing of a changeover circuit 29A applying position information of a picture position detection pattern received sequentially from a light receiving element 11 to convergence correction circuits 30, 31, 32, 50, 51, 52 relating to the projecting tubes 21, 22, 23, 41, 42, 43. Then the switching is implemented synchronously with two periods of vertical scanning with a switching signal from a switching signal generating circuit 33A sequentially. Thus, when an interlace signal is received, the projecting tubes 21, 22, 23, 41, 42, 43 always detect both an odd number field and an even number field and detect an average picture position sequentially and the occurrence of mis-convergence is reduced.

Filed: 1988-01-11
Abstract: PURPOSE:To easily prepare a dictionary by executing font determination by comparing minimum distance values discriminated by means of dictionaries prepared at every font. CONSTITUTION:A memory controller 4 sends four-font collating programs in a memory 3 to exclusive processors 5-8. Then one of the character-string picture and the data of character segmenting position of a memory 2 are transferred to the memory 3. Thereafter, collating processes are executed at each font at the processors 5-8 and the minimum distance value to each character picture stored in the memory 3 is outputted to the memory 3 so as to collate a sentence of a designated character number. Upon completion of the collation, a general purpose processor 1 finds the mean minimum distance value at every font from the received minimum distance values and adopts the font having the minimum distance value as the font. Then the processors 5-8 execute collating programs in parallel with each other and output collated results to the memory 3. After the collation is completed, completion data are returned to the processor 1. Upon receiving the completion data, the processor 1 receives the collated results stored in the memory 3.

Abstract: PURPOSE:To easily and accurately register binarized images by drawing a line on the binarizing boundary when those binarized images are registered in a recognizer after a basic object to be recognized is picked up. CONSTITUTION:An object to be recognized is picked up and a binarizing process is carried out. The binarized images are separated into the binarized images of the object to be recognized and a background based on a threshold value at that time. Then the boundary of the binarized images is written. The results of said operations are outputted to a monitor device. An operator of a recognizer compares the line drawing picture of a monitor with the object to be recognized. When coincidence is decided from said comparison, the binarized images obtained then and the threshold value are registered in a binarized image register and the recognizer. If no coincidence is decided, the threshold value is changed and the binarizing process is carried out again.

Title: Traveling controller for unmanned carrier
Inventor: HITOMI SHINICHI
IPC: G05D1/02
Filed: 1988-01-12
Abstract: PURPOSE:To prevent the runaway, the collision against obstacles, etc., of an unmanned carrier by deciding the occurrence of an error and performing the abnormality processing in case the detection of a station line is impossible within a set distance. CONSTITUTION:A traveling distance measuring means 79 measures the distances after an unmanned carrier 1 starts at the station lines ST1-STn respectively. When these measured distances exceed the distances set by a distance setting means 80 for each station, the detecting signals are sent from a detecting means 60. The abnormality processing means 90, 92 and 100 work to give the emergency stop to the unmanned carrier in case the detecting signal is received before detection of a desired station line. In such a way, the abnormality is detected in case the signal of the desired station is not detected within a distance obtained by adding the prescribed margin to the distance from the next station. Thus the carrier is urgently stopped. As a result, the carrier can be prevented from runaway, including such accidents as collision against obstacles.
