PURPOSE: To simplify the circuit constitution of the titled device and make the device suitable for small-sized cameras, by leading out two outputs in accordance with the incident angle of a light reflected from an object, and using one output as distance information under a prescribed condition.

CONSTITUTION: The titled camera is provided with an infrared LED17 which projects a light to an object 19, semiconductor position detector 21 which gives contrary changes to two outputs in accordance with the incident angle of a light reflected by the objective 19, control circuit 6 which controls the output of the LED17 so that the direct or indirect sum of the two outputs of the detector 21 attains to a prescribed value, and distance information detecting means 46 and 52. One output VA of the detector 21 is latched 54 as distance information when the sum of the two outputs of the detector 21 is a prescribed value.
