PURPOSE:To select a main object optionally among extracted objects by extracting all objects which have fine difference from an object whose value weighted for an object in each distance measurement area is maximum at the same time. CONSTITUTION:Light beams from a light source part 1 are split by a slit 2 into plural pieces of luminous flux, which are projected on an object; and its reflected light beams are made incident on photodetecting elements 70(70-1-70-n) and stored in the form of a object distance in a memory circuit 57. Values of weighting information which are stored previously in a weight information RAM 62 corresponding to respective distance measurement areas are read out by a reading circuit 63 and stored in registers 64 respectively. A CPU 53 processes weighted values for determining the order of respective distance measurement areas, extracts the objects having fine differences from the object whose weighted value is maximum at the same time, and displays them on the display device 69 in a finder. Consequently, a photographer can selects the main object optionally among the extracted objects. |
