Title: Image matching device
Inventor: NUMATA SABUROU
IPC: G03B3/00
Filed: 1977-12-28
Abstract: PURPOSE: To enhance the accuracy of detection of focus with a simple construction by bisecting the light from an objective lens with a split prism and obtaining the coincidence point of the photo detector outputs which have measured said light thereby performing imaging.  
     CONSTITUTION: When the images of an objective lens are not matched, the respective upper and lower halves of the images are deviated to the right and left by the refracting action of a split prism and the photo currents being differences are produced from the photo detectors 3a, 3b which are connected in opposite directions. These are logarithmically compressed with a log diode 5 or 6. Hence, when the images are matched, the voltage at the point P becomes approximately a reference voltage Vref and when not it becomes higher or lower than the reference voltage according to the deviations of the images and the patterns. A comparator 7 compares this with a reference voltage, producing signals of "H", "Vref", "L".  According to this, an LED 9 or 8 selectively emits light, indicating the ono- coincidence of the images in the finder, etc. and therefore the point where the LEDs  do not emit light is found out by moving the objective lens. Thereby, the detection accuracy of the focus may be enhanced.
