果を組み合わせた結果を出力する。The vibration detector 5 detects the amount of change in the rotational speed of the cylinder of the VTR, compares the amount of change with a predetermined threshold value, and the screen divided into a plurality of regions. The result of combining the result of comparing the variance value of the motion vector with the threshold value is output.

ＴＲにおいてカメラが振動すると回転ムラが生じ、回転
速度が変化し、その変化量はカメラの振動振幅の大きさ
に比例して大きくなるという関係がある。FIG. 6 shows the relationship between the amount of change in the rotation speed of the VTR cylinder and the vibration amplitude of the camera. Figure 6
As shown in, the VTR cylinder normally rotates at a constant speed, so there is no change in rotation speed.
In TR, when the camera vibrates, uneven rotation occurs, the rotation speed changes, and the change amount increases in proportion to the magnitude of the vibration amplitude of the camera.

るいは緩やかに動かすため、カメラの振動振幅が小さい
のに対し、誤記録状態ではカメラの動きが大きくなり振
動振幅が大きくなる。Considering the relationship between the vibration amplitude of the camera and the usage condition of the camera, the camera vibration amplitude is small because the camera is fixed or gently moved during normal photographing, whereas the camera vibration is small in the erroneous recording condition. And the vibration amplitude increases.
【００２８】よって、回転速度の変化量と所定のしきい
値ｘと比較することで、撮影状態と誤記録状態を識別で
きる。Therefore, by comparing the change amount of the rotation speed with the predetermined threshold value x, it is possible to distinguish the photographing state from the erroneous recording state.
【００２９】図７は、カメラの使用状態とその時の各領
域の動きベクトルの様子と動きベクトルの分散の関係を
示している。FIG. 7 shows the relationship between the use state of the camera, the state of the motion vector of each area at that time, and the dispersion of the motion vector.

そのため、通常撮影時には、各領域の動きベクトルの分
散が小さく、誤記録状態では分散が大きくなるという関
係がある。As shown in FIG. 7, during normal photographing such as fixed, panning, and tilt, the motion vector of each area is distributed in substantially the same size and direction. On the other hand, in the erroneous recording state, the motion vector of each area is in a completely different direction because the camera makes an irregular motion such as rotation.
Therefore, there is a relation that the dispersion of the motion vector of each area is small at the time of normal photographing and becomes large at the erroneous recording state.
【００３１】よって、動きベクトルの分散と所定のしき
い値ｙを比較することで、撮影状態と誤記録状態を識別
できる。Therefore, by comparing the variance of the motion vector with the predetermined threshold value y, the photographing state and the erroneous recording state can be identified.

量と所定のしきい値ｘとの比較結果と動きベクトルの分
散と所定のしきい値ｙとの比較結果を組み合わせた結果
とカメラの使用状態の関係を示している。FIG. 8 shows a result obtained by combining the result of comparison between the amount of change in the rotational speed of the VTR cylinder and a predetermined threshold value x, the result of comparison between the variance of the motion vector and the predetermined threshold value y, and the use of the camera. The relationship between states is shown.

影しても画面の動きは緩やかなために、動きベクトルの
分散は小さい。Depending on the use state of the camera, the photographer may stop and take a picture, or the photographer may take a picture while moving. When the latter photographer shoots while moving, the camera vibrates, and the amount of change in the rotation speed at that time is near a predetermined threshold value x. On the other hand, even if the photographer shoots while moving, the motion of the screen is slow, so the dispersion of the motion vector is small.

撮影状態の識別精度が向上する。Therefore, the erroneous recording state is set only when the variance of the motion vector is larger than the predetermined threshold value x and the change amount of the VTR rotation speed is larger than the predetermined threshold value y. In other cases, the recording state is set. By discriminating, the accuracy of discrimination between the erroneous recording state and the photographing state is improved.

It is possible to prevent an erroneous recording state that occurs during normal shooting with the camera in hand, by setting the erroneous recording state when the back surface faces the ground and the vibration of the camera continues to be large, and stopping the recording.

It is obvious that the same effect can be obtained by using only the amount of change in the rotation speed of the cylinder.
