Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To extract the parallax with high accuracy even to a natural image that includes both areas having the sudden and gentle changes of intensity and to accurately grasp the three-dimensional shape of an object. SOLUTION: Two sheets of images having the parallax between them are fetched, and the average and dispersion value of the nearby intensity are calculated for every pixel of each image. Then the local dispersion value of the inter-pixel intensity difference is calculated when one of both images is shifted, and the excitable and restrainable coupling load are decided between the elements of a neural network based on the former dispersion value. In this case, the excitable coupling load is decided based on the local pixel intensity average of every image or the similarity between the dispersed nearby pixels. At the same time, the similarity value is calculated based on both calculation results when one of both images is shifted. Based on these value, the corresponding relation is decided between the pixels included in the right and left images in the neural network.  Then the position of the pixel that outputs 1 shows the three-dimensional shape of an object.

IPC: B60R1/04
Filed: 1979-02-09
Abstract: PURPOSE:To make it possible to rake the mirror body automatically to a settled angle by effectuating conduction on the electromagnet when strong light emitted from the posterior light source has been thrown upon the rear-view mirror and optical rate detected through photoceptive element grows to more than the settled value. CONSTITUTION:When strong light from a following vehicle or another source has been thrown its incidence upon the rear-view mirror 10, the irradiating light makes the voltage applied from a light-receiving element 30 into less than the threshold voltage of an inverter 35. Then, the inverter 35 gives voltage at a high level making a capacitor 36 into non-conductive state. In consequence, input voltage of an inverter 37 grows to more than said threshold voltage resulting in giving output of low  level voltage. On the other hand, since an inverter 39 also gives output of low level voltage, a capacitor 40 grows to the conductive state, a transistor 42 is worked for  only T1 hour(s) to drive a solenoid 27b. This facilitates to excite an electromagnet  21, and to rake the mirror body 10 as shown by dotted lines.
