To provide an imaging apparatus capable of calculating an off-set of an angle speed sensor while suppressing the increase of a power consumption to the minimum value, without generating a troublesome of a user operation.SOLUTION: An imaging apparatus comprises: finder photographing detection means of detecting a photographing state in eye-contact to a finder; photographing preparation instruction detection means of detecting a photographing preparation instruction; angular speed detection means of detecting an angular speed; and a storage part that stores the angular speed detected by the angular speed detection means. When detecting a photographing state in eye-contact to the finder by the finder photographing detection means, a plurality of angular speeds detected in a predetermined time interval by the angular speed detection means is stored in the storage part. When detecting the photographing preparation instruction by the photographing preparation instruction detection means, the imaging apparatus comprises angular speed off-set calculation means of calculating an output off-set of the angular detection means by the plurality of angular speeds stored in the predetermined period before the photographing preparation instruction detection in the case where a change amount of the angular speed in the predetermined period before the photographing preparation instruction detection is in a predetermined value.SELECTED DRAWING: Figure 6 【課題】ユーザー操作の手間を生じさせることなく消費電力の増加を最小限に抑えて角速度センサのオフセットを算出できる撮像装置を提供する。【解決手段】ファインダに接眼した撮影状態を検知するファインダ撮影検知手段と、撮影準備指示を検知する撮影準備指示検知手段と、角速度を検出する角速度検出手段と、角速度検出手段で検出した角速度を記憶する記憶部と、を備えた撮像装置で、ファインダ撮影検知手段により、ファインダに接眼した撮影状態を検知すると、角速度検出手段により所定時間間隔で検出した複数の角速度を記憶部で記憶し、撮影準備指示検知手段が撮影準備指示を検知した時、撮影準備指示検知前の所定期間の角速度の変化量が所定値以内であった場合は、撮影準備指示検知前の所定期間に記憶された複数の角速度より角速度検出手段の出力オフセットを算出する角速度オフセット算出手段を備えた。【選択図】図６
