摘要： A camera system comprises a selector, an operable switch, a changing circuit and an inhibiting circuit. The selector selects one of a plurality of exposure lines. The changing circuit change as combination of the aperture value and the shutter speed value determine by both the selected exposure line and a brightness value in response to the operation of the operable switch. The inhibiting circuit inhibits the operation of changing circuit when a predetermined exposure line is selected by the selector. In the camera system, a photographer may only select the exposure mode through the operable switch in accordance with his intention and purpose in photography, and then the change of the exposure combination is inhibited in a certain exposure mode.

摘要： In still frame images from a film, the first frame of an image block is produced in a fade-in manner for gradually outputting a picture. If the end of a beginning part of a theme block is detected from information for a next frame, the process is advanced to a step to select a production method including relevantly large movement on the assumption that the scene is moved to an intermediate part of the theme block. If the intermediate part is ended, a different production method including relevantly small movement is selected on the assumption that the scene is moved to an end part.

摘要： A winding and rewinding apparatus for a camera comprises a winding mechanism, a detector, a rewinding mechanism, a selector and a controller. The winding mechanism winds the film frame by frame, and the detector detects the completion of exposure of the roll of film which is wound by the winding mechanism. The rewinding mechanism rewinds the film automatically in response to the detection of the detecting means. The selector includes a selecting switch which is operable manually, for selecting in response to the operation of the selecting switch one of a first mode in which the operation of the rewinding mechanism is permitted and a second mode in which the operation of the rewinding mechanism is inhibited irrespective of the detection of the detector. The controller controls the rewinding mechanism in accordance with the mode selected by the selecting switch. According to such arrangement, the user can select a manual rewinding mode or an automatic rewinding mode by a simple operation.
