PROBLEM TO BE SOLVED: To solve the problem that an image pickup device easily becomes larger in the case of arranging a photometry system and a rage-finding system independently. SOLUTION: In this photometry and range-finding device having an objective for photometry 3 and a pair of objective for range-finding 1 and 2 arranged at a specified base length on both sides with the objective 3 interposed therebetween, luminous fluxes passing through the objectives are respectively received by a photodetector for photometry 10 and a pair of photodetectors for range-finding 8 and 9 arranged on a single base plate 7. Then, the lens surface dimension in a direction (B-B direction) orthogonal to the base length direction in at least either the objective for photometry or the objectives for range-finding is made larger than that in the base length direction (A-A direction). |
