ABSTRACT:
In a camera with a line of sight detecting device, the optical axes of an observation optical system, illuminating means and photoelectric converting means are disposed so as to differ from one another, whereby it never happens-that in the observation optical system, illuminating light creates ghost, and the calculation of the direction of line of sight can be accomplished effectively.
