Abstract

In an automatic stabilization control apparatus that subjects a moving image picked up by a camera to automatic stabilization control, the apparatus comprises means for designating a range of frames which are to be subjected to automatic stabilization control (hereinafter referred to as a correction frame range); means for calculating a common area where the image is common among the frames within the correction frame range; automatic stabilization control means for subjecting each of the frames within the correction frame range to automatic stabilization control processing involving enlargement of the common area; and enlargement processing means for subjecting vicinity frames preceding and succeeding the correction frame range to enlargement processing.

Claims

1. In an automatic stabilization control apparatus that subjects a moving image picked up by a camera to automatic stabilization control,

an automatic stabilization control apparatus comprising:

means for designating a range of frames which are to be subjected to automatic stabilization control (hereinafter referred to as a correction frame range);

means for calculating a common area where the image is common among the frames within the correction frame range;

automatic stabilization control means for subjecting each of the frames within the correction frame range to automatic stabilization control processing involving enlargement of the common area; and

enlargement processing means for subjecting vicinity frames preceding and succeeding the correction frame range to enlargement processing.

2. The automatic stabilization control apparatus according to claim 1, wherein

the enlargement processing means enlarges, with respect to the vicinity frames preceding the start frame in the correction frame range, the frames such that the nearer the frame is to the start frame in the correction frame range, the higher the enlargement ratio thereof becomes, while enlarging, with respect to the vicinity frames succeeding the end frame in the correction frame range, the frames such that the nearer the frame is to the end frame in the correction frame range, the higher the enlargement ratio thereof becomes.

3. In an automatic stabilization control method in which a moving image picked up by a camera is subjected to automatic stabilization control,

an automatic stabilization control method comprising:

a step for designating a range of frames which are to be subjected to automatic stabilization control (hereinafter referred to as a correction frame range);

a step for calculating a common area where the image is common among the frames within the correction frame range;

an automatic stabilization control step for subjecting each of the frames within the correction frame range to automatic stabilization control processing involving enlargement of the common area; and

an enlargement processing step for subjecting vicinity frames preceding and succeeding the correction frame range to enlargement processing.

4. The automatic stabilization control method according to claim 3, wherein

the enlargement processing step is for enlarging, with respect to the vicinity frames preceding the start frame in the correction frame range, the frames such that the nearer the frame is to the start frame in the correction frame range, the higher the enlargement ratio thereof becomes, while enlarging, with respect to the vicinity frames succeeding the end frame in the correction frame range, the frames such that the nearer the frame is to the end frame in the correction frame range, the higher the enlargement ratio thereof becomes.

5. In a computer readable recording medium having an automatic stabilization control program, for subjecting a moving image picked up by a camera to automatic stabilization control, recorded thereon,

a computer readable recording medium wherein the automatic stabilization control program causes a computer to carry out:

a step for designating a range of frames which are to be subjected to automatic stabilization control (hereinafter referred to as a correction frame range);

a step for calculating a common area where the image is common among the frames within the correction frame range;

an automatic stabilization control step for subjecting each of the frames within the correction frame range to automatic stabilization control processing involving enlargement of the common area; and

an enlargement processing step for subjecting vicinity frames preceding and succeeding the correction frame range to enlargement processing.

6. The computer readable recording medium according to claim 5, wherein

the enlargement processing step is for enlarging, with respect to the vicinity frames preceding the start frame in the correction frame range, the frames such that the nearer the frame is to the start frame in the correction frame range, the higher the enlargement ratio thereof becomes, while enlarging, with respect to the vicinity frames succeeding the end frame in the correction frame range, the frames such that the nearer the frame is to the end frame in the correction frame range, the higher the enlargement ratio thereof becomes.
