Method of automatically controlling taking exposure and focusing in a camera and a method of controlling printing exposure

摘要

A scene to be photographed is divided into a plurality of scene divisional areas disposed in a matrix pattern. A plurality of distance measuring points are two-dimensionally disposed in correspondence with the scene divisional areas. A change with time in distance data is detected at each distance measuring point. A distance measuring point having a change greater than a threshold value is extracted as a main object candidate point. Of the main object candidates points, the distance measuring point having the shortest distance data falling within a predetermined range from the shortest distance data are judged as the effective distance measuring points where a main object is present. The focus of a taking lens is adjusted in accordance with the distance data of the effective distance measuring points. The taking exposure amount is controlled in accordance with an average value of brightness data of effective scene divisional measuring points. In a preferred embodiment, position information and divisional photometry information are recorded on a photographic film during photography. A photographic printer then measures the density of a plurality of frame divisional areas corresponding to the scene divisional areas. In accordance with the measured density and the brightness and exposure amount recorded on a photographic film, a shift of the taking exposure amount from an ideal characteristic is obtained. An ideal and elementary printing exposure amount is corrected by using the shift amount to determine a final elementary printing exposure amount.
