摘要:
In a digital still camera, it is cumbersome for the camera user to set an image photographing method and saving method of the photographed image, which are suitable for each object. When a photographing mode suitable for a moving object such as a “sports mode” is set, normal photographing is done, and the photographed image is lossless-compressed and saved. When a photographing mode suitable for a still object such as a “portrait mode” is set, a high-resolution image is captured by pixel shift photographing. The photographed image is lossy-compressed and saved.

An image blur prevention apparatus includes a movable member (e.g., a correction optical system) which moves for image blur prevention, a holding device (e.g., a locking member for holding the correction optical system) which holds the movable member, the holding device being changeable between a state in which a predetermined holding operation is performed and a state in which the predetermined holding operation is not performed, an operating device which operates the movable member for image blur prevention (e.g., operates the correction optical system in accordance with an image blur signal) at a predetermined position as a control center position (e.g., a position at which the optical axis of the correction optical system matches another optical axis), and a control device which controls movement of the movable member between the position at which it is held by the holding device and the predetermined position, and which controls a process of the movement between the holding position and the predetermined position.

An image stabilizing apparatus is provided with a plurality of gain setting means arranged in a feedback loop system, a gain switching means for, when an oscillation of the feedback loop system is detected based on an output from a deviation amount detection means, switching gains in the gain setting means, a plurality of phase compensation means arranged in the feedback loop system, and a phase compensation switching means for, when an oscillation of the feedback loop system is detected based on an output from the deviation amount detection means, switching the phase compensation means. The oscillation is suppressed by switching the gains in the gain setting means, switching the phase compensation means, or simultaneously switching them.

In an image stabilizing device or system of the kind having a shake detecting sensor which detects a shake of the device or system and is arranged to require a lapse of time before the sensor becomes capable of stably detecting the shake after the start of the sensor, and an image shake correcting member which performs an image shake correcting action according to the output of the shake detecting sensor, a control circuit is arranged to allow the image shake correcting member to commence its image shake correcting action according to the output of the shake detecting sensor after the lapse of a given period of time from the start of the operation of the shake detecting sensor, and a varying circuit is arranged to vary the given period of time. The length of waiting time necessary before the detecting sensor becomes capable of stably performing a shake detecting action is thus arranged to be variable according to the operating state of the device or system, so that an image stabilizing action can be accomplished as soon as possible.
