Abstract
PURPOSE: To detect a location easily and highly accurate by a mechanism wherein time series output signals from a scanning type camera element such as a photosensor-array-device disposed approximately conforming to a surface onto which light flux is projected are devided every fixed section and the quantities are compared.
CONSTITUTION: Light flux is projected by the luminescence of a light source 2, and the output of a photosensor-array-device 3 is read by the functioning of a drive circuit 7 under a condition that the reflected light flux of the projection is projected at a location corresponding to a focus adjusting condition of an image formation lens 1 to a body at that time on a sensor surface of the said device 1. An integration circuit 11 is reset by shift pulses ϕSH at that time while a control circuit 12 responds to the resetting and prescribes timing on the basis of transfer clock pulses ϕ2. A sample-holding circuit 13 sample-holds the output of the integration circuit 11 obtained by the inversion and noninversion of a signal inversion circuit 10, and outputs to a display control circuit 15.
