Abstract
A distance measuring method and apparatus accurately detects point in time when reflected slit light passes a cell constituting an imaging plane. Each of the cells constituting the imaging plane includes a pair of photo-sensors disposed side by side along the direction of movement of the reflected slit light. A comparator compares photoelectric currents outputted from the pair of photo-sensors, and a point in time at which the reflected slit light moves from a first one to a second one of the photo-sensors of the cell is determined based on the output of the comparator. The point in time thus detected is determined as a point in time at which the reflected slit light passes the cell and is used for measurement of the distance to the subject for measurement.
