Camera provided with camera-shake compensation functionality
View Patent ↗A camera provided with camera-shake compensation functionality that comprises a camera-shake detector, a photographing mode selector, an adjuster, and an anti-shake mechanism. The camera-shake detector detects a quantity of shake of the camera. The photographing mode selector is used to select a photographing mode. The adjuster adjusts output signals from the camera-shake detector, in accordance with the photographing mode selected by the photographing mode selector. The anti-shake mechanism compensates for a camera-shake to be counteracted, based on the output signals adjusted by the adjuster.
1. A camera provided with camera-shake compensation functionality, comprising:
a camera-shake detector that detects quantity of shake of said camera;
a photographing mode selector that is used to select a photographing mode;
an adjuster that adjusts output signals from said camera-shake detector, in accordance with said photographing mode selected by said photographing mode selector; and
an anti-shake mechanism that compensates for a camera-shake to be counteracted, based on the output signals adjusted by said adjuster,
wherein said adjuster extracts predetermined frequency components from the output signals in accordance with said photographing mode, and
wherein said photographing mode is classified by a set of information including at least one of a size of an object, a distance to said object, a magnification, a quantity of movement in an image plane, a panning operation, and use of a tripod.
2. A camera according to claim 1 ,
wherein said adjuster extracts frequency components of the output signals in a high frequency range when said photographing mode is set as an astronomical photographing mode;
said adjuster extracts frequency components of the output signals from about the high frequency to about first middle frequency ranges when said photographing mode is set as a bird photographing mode;
said adjuster extracts frequency components of the output signals from about the high frequency to about second middle frequency ranges, the second middle frequency range being lower than the first middle frequency range, when said photographing mode is set as a train photographing mode;
said adjuster extracts frequency components of the output signals from about the first middle frequency to about low frequency when said photographing mode is set as a portrait photographing mode; and
said adjuster extracts frequency components of the output signals in the low frequency range when said photographing mode is set as a night view photographing mode.
3. A camera according to claim 2 ,
wherein said camera-shake detector comprises a gyro sensor, and said adjuster comprises a plurality of band pass filters, each having a different frequency band, and a switch that selectively connects said gyro sensor to one of said band pass filters.
4. A camera according to claim 2 ,
wherein said high frequency range is around 30 Hz, said first middle frequency range is around 20 Hz, and said low frequency range is around 10 Hz.
