摘要： An automatic-focusing camera is provided with a multiple-point distance-measurement device having a plurality of distance-measurement areas, a multiple-division photometry device having a plurality of photometry areas, and a multiple-division light-amount-control device having a plurality of light-amount-control areas. Part of the photometry areas and part of the light-amount-control areas correspond to the distance-measurement areas. When a taking lens is focused on a subject, its focus is locked. Out of the information obtained from the multiple-point distance-measurement device, a set of information obtained when the focus of the taking lens is locked is compared with a set of information obtained immediately before a shot is taken, and thereby a change in picture composition after the locking of the taking lens focus is detected. This makes it possible to achieve exposure control in ambient-light shooting and light amount control in flash shooting in accordance with a change in picture composition. Based on the information obtained from the multiple-point distance-measurement device, the subject and the background are identified, and, in accordance with the distribution of the subject and the background, the reference value to be used to stop emission of illumination light and the contribution ratios of the individual light-amount-control areas relative to the total amount of light received are determined to achieve light amount control in flash shooting.
