Abstract: PURPOSE:To obtain an adequate tomographic image by correcting the positional data of a scintillation image by the data on the extent of movement and annihilating effectively the nonuniformity even if partial nonuniformity exists in a detector. CONSTITUTION:It is assumed here that photographing with an ECT device is executed at every step of, for example, 10 deg. angle. More specifically, the data are collected by 36 times of photographing. A top plate is at the origin of the movement when the rotating angle is 0 deg.. The top plate is moved by DELTAY/36 when the rotating angle is 10 deg.. The top plate is moved by DELTAY/36X2 when the angle is 20 deg. and eventually the top plate moves to DELTAY at DELTAY/36X36 when the plate rotates 360 deg.. However, the collected images move by DELTAY/36 each in this state and the correct images are not formable and therefore the Y signal is added by each DELTAY/36 from a detector 3. The images are thereby collected at the correct position and the adequate tomographic image is obtd.

Title: Lane deviation alarm device
Inventor: SAKAMOTO HIROBUMI
IPC: G08G1/04
Filed: 1995-01-31
Abstract: PURPOSE: To generate a stain detection alarm only when the detection performance of an image pickup sensor is lowered without requiring a new additive for stain detection by counting the number of times of loop in which a lane detection can not be performed within a prescribed time and energizing a different alarm means because a stain a sensor occurs when this number of times exceeds a threshold. CONSTITUTION: An image processor 4 detects the lane on a road by binarizing the image signal obtained from an image pickup sensor 1. When the lane detection can not be performed in the one loop in a program routine because this image processor 4 uses the processing program, a lane detection error is regarded to be generated and the number of times of this error is counted. When this number of times exceeds a threshold within a prescribed time, the stain of the image pickup sensor 1 is regarded to be generated and an alarm is generated by energizing the alarm means 6 which is different from the alarm means 5 of a lane deviation. Therefore, the lowering of the detection force due to the stain of a lens surface can be detected without an addition product.
