PURPOSE:To focus on the object of photographer's intention in any image by performing weighting by means of object distance information and an object position in a photographing image. CONSTITUTION:Distance information stored in a memory circuit 57 is sequentially called out by a CPU 53. When there is not an object closer than the shortest photographing distance or even if there is, but on the periphery of a photographing image, the object distance information of a distance measuring area is reset to an infinite level, and weighting information Dij which responds to the distance information of each distance measuring are is read out from a Dij information RAM 69. The weight information of registers 1-n, which responds to each photodetector is also called out and calculated in the CPU. Each distance measuring area is ordered and the highest weighted distance measuring area is selected. Then a signal is sent to a lens driving motor driving circuit 68, and the lens is driven in the way that it is focused on said selected distance measuring area. Thus focusing precisely on an original main object becomes possible. |
