Abstract:
A device for correcting a tremble of a focused image, for a camera including a photographing optical system, and a photographing control system which records an optical image, formed on a photographing medium, on said photographing medium by controlling an image capturing operation, said device comprising:a tremble detector that detects a direction and a quantity of a tremble of the camera; a correction optical system that is included in the photographing optical system and corrects a tremble of said optical image; a driving device that drives said correction optical system; a tremble position detector that detects a tremble position on a focal plane, through which an optical axis of another optical system included in the photographing optical system extends and on which said optical image is formed by the photographing optical system, said tremble position being moved in accordance with said tremble of the camera, said optical axis of said other optical system extending through a center of said focal plane, when an optical axis of said correction optical system is positioned at an original point at which said optical axis of said correction optical system is coaxial with said optical axis of said other optical system; and a controlling system that calculates driving data of said correction optical system based on said tremble position in order to cancel said tremble, and controls said driving device based on said driving data; wherein said controlling system controls said driving device such that a first correctable range, of said correction optical system on said focal plane when the camera is in a standby state, is smaller than a second correctable range, of said correction optical system on said focal plane when the camera is in an image capturing state.
