摘要： An exposure control circuit associated with TTL automatic electronic flash includes a diaphragm control circuit. When the electronic flash is mounted on a TTL direct photometry camera capable of photometry of reflection from a film surface in order to take a picture with the aid of the electronic flash, the diaphragm control circuit assures the emission of light from the electronic flash in a reliable manner, by automatically establishing a diaphragm value between a given diaphragm value and a minimum diaphragm value, the established diaphragm value assuring a proper exposure with an exposure period which is closely synchronized with the operation of the electronic flash.

摘要： A pick-up system includes means for recognizing the displacement of objects to be photographed relative to the optical reproduction plane. The shutter of the pick-up system is actuated according to the relative motion of said objects. In a pick-up system comprising a variable diaphragm and a replaceable film of a special sensitivity, e.g. in an automatic camera, the shutter speed, being a function of the relative motion of the objects, determines the aperture of the diaphragm with respect to the sensitivity of the film.

摘要： An imaging apparatus having a function of detecting a face from an image signal on which a focusing frame is superimposed is configured so that a face selected to be a main object can continue being selected to be a main object even if a focusing frame is displayed as superimposed on the face. A central processing unit moves a position of a focusing frame to be displayed by a display unit to a position corresponding to a detected object if a ratio of a size of the detected object to a size of the focusing frame displayed on the display unit is greater than or equal to a predetermined threshold, and does not move the position of the focusing frame to be displayed by the display unit to a position corresponding to the detected object if the ratio is less than the threshold.
