Device for controlling image signal recording operation
First Claim
1. A device for controlling an image signal recording operation, said device comprising:
- a photographing optical system by which an image is formed on a photo imaging plane;
a scanner optical system that reads an image on a scanning plane to form an image on a sensor imaging plane;
a recording medium detachably mounted at a location containing said photo imaging plane and said scanning plane; and
a control system that adjustably controls a position of at least one of said photo imaging plane and said scanning plane so that said photo imaging plane and said scanning plane are coincident with each other whether or not said recording medium is mounted at said location;
a recording medium sensing system that senses whether or not said recording medium is mounted at said location.

Abstract
An image signal recording operation control device is provided in a still video camera. The control device has a photographing optical system by which an image is formed on an electro-developing recording medium, by which the image is electronically developed. The control device also has a scanner optical system by which the image developed by the electro-developing recording medium is formed on a sensor imaging plane. A line sensor is provided for scanning on the sensor imaging plane to read out the image. When the electro-developing recording medium is not mounted in the still video camera, i.e., when an aerial image formed by the photographing optical system is read by the line sensor, the scanner optical system is displaced by a predetermined amount along the optical axis, in comparison with a state in which the electro-developing recording medium is mounted, so that the scanner optical system can form an in-focus image on the sensor imaging plane.

13. A device for controlling a recording operation in which an image signal is obtained by an imaging device, said device comprising:
-
a scanner optical system forming an image on said imaging device; a photographing optical system by which a light beam from an object is condensed so that the object image is formed on a focusing position; an electro-developing recording medium detachably mounted between said photographing optical system and said scanner optical system, so that the object image is recorded in said electro-developing recording medium; means for sensing whether or not said electro-developing recording medium is mounted; and means for controlling a position of at least one of said photographing optical system and said scanner optical system, in an optical axis thereof, in such a manner that said focusing position and a conjugate position of said imaging device with respect to said scanner optical system are always coincident with each other, based on an output signal of said sensing means. - View Dependent Claims (14)

15. A device for controlling an image signal recording operation, said device comprising:
-
a photographing optical system which forms an image on a photo imaging plane; a scanning optical system that scans an image provided on a scanning plane, and forms an image on a sensor imaging plane; a recording medium detachably mounted at a location containing said photo imaging plane and said scanning plane, an image being optically recorded in said recording medium; and a control system that controls a position of at least one of said photo imaging plane and said scanning plane by moving at least one of the photographing optical system and the scanner optical system along an optical axis in association with whether or not said recording medium is mounted at said location so that said photo imaging plane and said scanning plane are coincident with each other whether or not said recording medium is mounted at said location.
