A lens device is provided and includes: at least two lenses; and a lens frame holding the at least two lenses. The lens frame includes a first lens frame holding one of the at least two lenses and a second lens frame holding another of the at least two lenses, and the first lens frame and the second lens frame are attached in a line contact in circumferential directions thereof. The first lens frame and the second lens frame are bonded after an optical adjustment of the at least two lenses by relatively swinging the first lens framed and the second lens frame with respect to the line contact.

The present invention is concerned with an electronic still camera for photographing a subject by use of an image sensing device such as a solid state image sensing device and the image signal thereof is recorded into a rotary recording medium such as a magnetic disc. With this electronic still camera, photographing in an electronic view finder ( EVF) mode and a movie still mode in addition to a normal mode can be performed. The EVF mode is the mode for making exposure of the image of the subject to the normally open image sensing means by use of an electronic finder to observe the subject, and subsequently, releasing an exposure device for a period of time required for the exposure to make exposure of the image of the subject to an image sensing device. The movie still mode is the mode for steadily rotating a spindle motor in synchronism with a synchronous signal generator, outputting a video signal to the outside through an interface and recording a still image into the rotary recording medium in response to an exposure command.

A lens device is provided and includes: a housing having a first fixed axis fixed in a transverse direction and a second fixed axis fixed in a longitudinal direction; a first slider supported so as to be slidable along the first fixed axis; a second slider supported so as to be slidable along the second fixed axis; a first movement bar fixed to the first slider in the longitudinal direction; a second movement bar fixed to the second slider in the transverse direction; a lens holding frame supported so as to be slidable along the first movement bar and the second movement bar; and a guide bar fixed to the housing in a direction perpendicular to the optical axis. One of the first and second sliders has an engagement section engaged with the guide bar so as to be regulated in the optical axis direction.

An electronic still camera which photographs an object by image pickup means such as a solid image pickup element or the like and records the video signal of the object into a rotary recording medium such as a magnetic disc or the like. The electronic still camera includes a mechanical shutter and an electronic shutter function to control electrically the accumulation time of the image pickup means and it is adapted such that, when the shutter speed is slower than a predetermined value, it controls a time for exposure to the image pickup means by the mechanical shutter and, when the shutter speed is higher than the predetermined value, it controls the exposure time to the image pickup means by means of the electronic shutter function and also controls the mechanical shutter to remain open at least for the exposure time.

A rotary shutter device for use in an electronic still camera or a VTR camera has an XY-addressable solid-state imaging device for converting an optical image read by successive horizontal scanning into a video signal, a shutter blade disposed in front of the solid-state imaging device and rotatable about its own axis, the shutter blade having at least one opening for transmitting light therethrough onto the photodetector surface of the solid-state imaging device, and an adjusting blade disposed adjacent to the shutter blade for varying the opening angle of the opening. The shutter and adjusting blades are rotatable together in a direction to successively expose the solid-state imaging device to incident light in the direction in which the solid-state imaging device is vertically scanned. The scanning of the solid-state imaging device for one field is completed between two successive exposures thereof through the opening in the shutter blade.
