Electronic still camera

A still camera for recording image data onto a recording medium, comprising:

• a photographing optical system that passes light from an object to be photographed and forms an image of said object;
• a finder optical system for receiving light passed through said photographing optical system;
• a pickup device that receives said image of said object from said photographing optical system and outputs an image signal that corresponds to said image of said object;
• a positioner that positions said pickup device at a first position where said pickup device is interposed between said photographing optical system and said finder optical system when photographing is executed, and for positioning said pickup device at a second position where said pickup device is located out of an optical path of said photographic optical system;
• and
• a recorder that records said image signal from said pickup device onto said recording medium.

A still camera for recording image data onto a recording medium, comprising;

• an optical system that passes light from an object to be photographed and forms an image of said object;
• a photometric unit that detects a brightness of said object in accordance with said light that passes through said optical system;
• a pickup device that receives said image of said object from said optical system and outputs an image signal that corresponds to said image, said pickup device being shiftable between a first position where said pickup device is interposed with an optical path of said optical system and a second position where said pickup device is located out of said optical path of said optical system;
• an aperture that limits an amount of said light that forms said image that is received by said pickup device;
• means for calculating an aperture value and a shutter speed based upon an output of said photometric unit;
• a recorder that records said image signal outputted from said pickup device onto said recording medium;
• release means for initiating a photographing operation;
• and
• a positioner that positions said pickup device to said first position and executes said photographing operation in accordance with said aperture value and said shutter speed calculated by said calculating means when said release means is operated.

A still camera for recording image data onto a recording medium, comprising:

• an optical system that passes light from an object to be photographed and forms and image of said object;
• a finder optical system for receiving light passed through said optical system;
• a filter member that is fixably arranged between said optical system and said finder optical system;
• a pickup device that receives said image of said object from said optical system and outputs an image signal that corresponds to said image;
• a positioner that positions said pickup device at a first position where said pickup device is interposed between said optical system and said finder optical system when photographing is executed, and for positioning said pickup device at a second position where said pickup device is located out of said optical path of said optical system;
• and
• a recorder that records said image signal outputted from said pickup device onto said recording medium.

A still camera for recording image data onto a recording medium, comprising:

• an optical system that passes light from an object to be photographed and forms an image of said object;
• a finder optical system that receives said light that passes through said optical system;
• a pickup device that receives said image of said object and outputs an image signal that corresponds to said image;
• a filter member that is provided in front of said pickup device for allowing said light passing through said optical system to pass through said filter member;
• a positioner that positions said pickup device at a first position where said pickup device is interposed between said optical system and said finder optical system when photographing is executed, and for positioning said pickup device at a second position where said pickup device is located out of an optical path of said optical system;
• and
• a recorder that records said image signal outputted from said pickup device onto said recording medium.

A still camera for recording image data onto a recording medium, comprising:

• a first optical system that passes light from an object to be photographed and forms an image of said object;
• a finder optical system that receives light passed through said first optical system;
• a pickup device that receives said image of said object formed by said first optical system and outputs an image signal corresponding to said image;
• a positioner that positions said pickup device at a first position where said pickup device is interposed between said first optical system and said finder optical system when photographing is executed, and for positioning said pickup device at a second position where said pickup device is located out of an optical path of said first optical system;
• and
• a focusing detector that detects a focusing condition based upon said outputted image signal from said pickup device when said pickup device is located at said second position.

A still camera for recording image data onto a recording medium, comprising:

• a pickup device that receives an object image and outputs an image signal that corresponds to said object image;
• an electronic shutter that controls a period of time in which said pickup device receives said object image;
• an aperture that controls an amount of light that is allowed to be incident to said pickup device;
• a positioner that positions said pickup device at a first position when a photographing operation is executed, and for positioning said pickup device at a second position when said photographing operation is not executed, a photometric operation being executed when said pickup device is positioned at said second position;
• and
• a driver that drives said aperture and said electronic shutter in such a fashion that when said photometric operation is executed, said electronic shutter being driven with a first appropriate shutter speed with said aperture being fully opened, while said photographing operation is executed with a second appropriate shutter speed and appropriate aperture value, respectively.

A still camera, comprising:

• a two-dimensional pickup device that receives an object image to be recorded;
• a positioner that positions said pickup device at a first position when a photographing operation is being executed, and positions said pickup device at a second position when said photographing operation is not being executed;
• an optical system that directs said object image to said pickup device when said pickup device is located at said second position, said optical system including a focusing optical system that forms an image to be used for detecting a focusing condition and a colorimetric optical system for forming an image to be used for detecting a color temperature of said object;
• and
• a detector that detects said focusing condition of said object image in accordance with said object image received by said pickup device when said pickup device is located at said second position.
