s u201d is superimposed is set as a main object region or a main subject region at this time the control microcomputer 30 stores in the memory its image information or image characteristic extracted by the c mos sensor 40 upon the main object region as a reference of the character then after the main object region is set the control microcomputer 30 compares new image information or image character extracted by the c mos sensor 40 upon image in the photographing region with the reference of the character which has been stored in the memory then when a part or piece of the new image information which is generally coincident with the reference of the character is detected the control microcomputer 30 updates the part or piece as the main object region then as shown in fig8 c the microcomputer 30 moves the scope u201c s u201d to the updated main object region in this manner the scope u201c s u201d is moved to follow or trace the movement of the object u201c m u201d a photographing condition is determined on a basis of the main object region that is for example when the main object region is set by superimposing the scope u201c s u201d over the object u201c m u201d focusing areas or focusing regions 2 c 2 b and 2 a over which the scope u201c s u201d superimposes following the movement of the object u201c m u201d are selected sequentially as shown in fig9 a 9 b and 9 c and the object u201c m u201d is brought.
