An image processing device compensates an original image for helping deteriorated human vision characteristics and displays the compensated image. Declines in a spectral sensitivity characteristic is compensated for by multiplying a brightness value of the original image by an inverse characteristic 1/A of a relative spectral sensitivity characteristic A in reference to a predetermined spectral sensitivity characteristic of a standard person. The first compensated image q(x,y) for defocus, or declines in accommodation characteristic, is obtained by a convolution integral of an original input image f(x,y) and a function j(x,y). The second compensated image m(x,y) for declines in sensitivity to cut-off frequency is obtained by a convolution integral of an original input image q(x,y) and the function p(x,y). The j and the p vary utilizing a radius of a blurred image and the cut-off frequency as a parameter, respectively. The image processing device enables an observer to recognize the original image as it is or as observed by the standard person, regardless of age or individual variations.

An image sensing device is provided with an expanded dynamic range when it photographs a moving object. A first gray value D1 of first picture taken with first exposure time is read in the first time interval and a second gray value D2 of second picture taken with second exposure time is read in the second time interval. Two function values f(D2) and g(D2) are calculated with respect to the second gray value D2. Then, a weight coefficient with respect to the function f(D2) is multiplied by the first gray value D1 and a weight coefficient with respect to the function g(D2) is multiplied by the second gray value D2. Those multiplied gray values are summed up. Such calculation of multiplying and summing up is carried out in each picture element of the first picture and the second picture, respectively.

A 3D volume measuring apparatus using an optical measuring technique performs an accurate measurement by using a common master clock signal to move a slit beam and to perform a measuring operation using the slit beam. An optical sensor has a slit beam source which projects the slit beam onto a surface of an object. A video camera receives an image of the optical cutting line. A master clock pulse generating unit is provided for generating master clock pulses. The slit beam is scanned on the object in synchronization with the master clock pulses. Information of the image of the optical cutting line is obtained in synchronization with the master clock pulses, so that the contour of the vertical section corresponding to the optical cutting line is obtained. A chamber volume correcting method using the 3D volume measuring apparatus is provided in which method an exact cutting depth for a cylinder head can be calculated so that a chamber of the cylinder head has an exact target volume. The cutting depth is determined in accordance with the measured volume of the chamber before a finish machining is performed.

A system for measuring three-dimensional shapes and dimensions includes: an imaging unit which faces an object with shape changes on the surface and images by means of a TV camera the slit line formed on the object surface by projecting slit light from a slit light source at a fixed angle; and a surface feature extraction member for extracting features representing the shape changes of the object surface, based on the changes of the XYZ coordinate values of the object surface detected by triangulation based on the centroid position of the intensity distribution of the slit line image corresponding to the scanning lines from the TV camera. Based on features thus extracted, the surface shape of the object can be measured rapidly with high precision.

An XYZ coordinates measuring system has a slit light source for projecting a slit light beam onto the surface of a work to be measured with a predetermined angle. Furthermore a television camera takes a light line formed on the surface of the work by the slit light beam to generate an output video signal. A coordinate measuring circuit has a look-up table for previously storing the interrelationship between the horizontal and vertical imaging positions of the light line and the XYZ coordinates on the surface of the actual work. The coordinate measuring circuit is adapted to process the video signal to detect the horizontal and vertical imaging positions Ks and Ls of the light line and to output the XYZ coordinates on the surface of the work from the look-up table, depending on the detected horizontal and vertical imaging positions Ks and Ls, the XYZ coordinates on the surface of the work can thus be real-time measured along the light line.

A noise supply suppression electrode arrangement for use in a distributor employed in an ignition system of an internal combustion engine of an automobile or the like. A rotor of the distributor is integrally formed by a dielectric material, such as ceramic, and a rotor electrode is mounted on a turn table of the rotor, the tip of the rotor electrode being located a predetermined distance from the edge of the turn table, so that discharge between the rotor electrode and a counterelectrode occurs through the rotor dielectric material.
