Abstract
Dual video and still-film camera embodying video recorder camera technology in two popular types of still-film camera: single-lens reflex (SLR) (1) and compact (2). The most advanced digital image-sensing semiconductor chip (charge- coupled device or CCD) (4) (21) and circuit board (8) (23), as well as other functional video camera components, are combined with the conventional apparatus of the still-film camera to support the video and still-film modes of photography in a single camera casing. By means of a manual switch (9) (24) or, as an alternate embodiment, an electrical switch, the user can extend the digital image sensor (4) (21) into the light-image line of sight in order to activate video operation or can retract the image sensor in order to allow still-film operation unimpeded by the video apparatus.
Claims3
A camera combining user-selected apparatus for still-film photography and user-selected apparatus for video photography, comprising
- a. an electronic image sensor with circuit board which elements can be extended into and retracted from the light-image line of sight as necessary for video or still-film operation,
- b. an electrical contact as signaling means for the camera micro controller to enable or disable certain elements, such as mirror, shutter, an aperture diaphragm, maintaining them in fixed positions needed for still-film or video operation,
- c. a conventional still-film photographing apparatus, with elements including film spool, film track, film controls, view finder, lens, flash device, and shutter and aperture diaphragm controls, and
- d. a conventional video photographing apparatus, with elements including tape deck and spools, video eyepiece, video head drum, sound recorder, and playback mechanism, and controls.
