<p>PROBLEM TO BE SOLVED: To make a camera small in size and light in weight without requiring extra space even when a camera shake correction function is provided by forming a camera shake detecting sensor and a range-finding sensor on a common photodetector to be one chip and making common use of an optical system common. SOLUTION: The camera shake detecting sensor and the rangefinding sensor are formed on the common photodetector 44 so as to be one chip and also the optical system is made common. For example, the camera shake detecting sensor is used also as the range-finding sensor. A 1st lens array 41 is the combination of two convex lenses and a 2nd lens array 42 is the combination of two concave lenses, which form a subject image and improve aberration characteristic on two optical axes. Light harmful to the sensor is cut by a light shielding sheet 43. The photodetector 44 formed of one chip semiconductor being the main body of the sensor detects the light from the subject by using two light receiving areas 45 and 46.</p> |
