DYNAMIC IMAGE DISPLAY METHOD, DYNAMIC IMAGE DISPLAY SYSTEM, AND WIDE-ANGLE DYNAMIC IMAGE CAPTURING DEVICE
First Claim
1. A method for displaying a video comprising:
- cutting out a portion of a first still image imaged by a wide-angle lens and producing a display data for a first display image base on the portion of the first still image;
specifying a changed amount in a imaging angle from the imaging timing for a previously cut-out still image to the imaging timing for the first still image whose portion is being cut-out, before cutting out a second or later still image imaged by the wide-angle lens;
and producing a display data for a second or later display image by cutting out a portion of the second or later still image as well as shifting a cut-out region of the second or later still image from that of the first still image so as to cancel the changed amount in the specified imaging angle.

Abstract
At least an embodiment enables displaying of a video image of a desired subject or a direction without a need for a camera operator to pay a special attention to the desired subject or the direction. The video displaying method may include cutting out a portion of a still image imaged by the wide-angle lens and producing a display data for a first display image, specifying a changed amount of an imaging angle from the imaging timing for the previously cut-out still image to the imaging timing for the still image to be cut-out, cutting out a second or later still image imaged by the wide-angle lens as well as shifting the cut-out region for the second or later still image so as to cancel the specified change amount of the imaging angle, forming a display data for the second or later display images.

2. A method for displaying a video comprising:
-
cutting out a portion of a first still image imaged by the wide-angle lens and producing a display data for a first display image capturing a desired subject; specifying a changed amount in a imaging angle from the imaging timing for a previously cut-out still image to the imaging timing for the first still image whose portion is being cut-out, and a changed amount in a relative angle between the imaging position of the previously cut-out still image and the first still image whose portion is being cut-out with respect to the position of the subject, before cutting out a second or later still image imaged by the wide-angle lens; and producing a display data for a second or later display image by cutting out a portion of the second or later still image as well as shifting a cut-out region of the second or later still image from that of the first still image so as to cancel the changed amounts in the specified imaging angle and the relative angle.

3. A video displaying system comprising:
-
a memory unit structured to store a plurality of saved still image formed with adding angle information specifying an imaging angle or a changed amount of the imaging angle, to each of still image data imaged continuously by the wide-angle lens; a cut-out displayed image producing unit structured to cut out a portion of the saved still image stored by the memory unit in the order of imaging and produces a display data for a plurality of display images; and a display unit structured to displays a plurality of display images in order based on a plurality of display data produced by the cut-out displayed image producing unit, wherein the cut-out displayed image producing unit is structured to cut out a portion of the still image by shifting a cut-out region of the still image so as to cancel the changed amount of the imaging angles between the still image whose portion is to be cut-out and the previously cut-out still image during cutting out a second or later still image, and the changed amount of the imaging angles is specified based on the change in the imaging angles between the saved still image data whose portion is to be cut-out and the previously cut-out saved still image data and angle information indicating the changed amount.

4. A video displaying system comprising:
-
angle information that specifies an imaging angle or a changed amount of the imaging angle added to each of plurality of still image data continuously imaged by using a wide angle lens; a memory unit structured to store a plurality of saved still image data each of which includes the imaged position and imaged position information indicating the amount of a positional change; a cut-out displayed image producing unit structured to cut out a portion of an image of the saved still image data stored by the memory unit in the order and produces a display data for a plurality of display images displaying a predetermined subject; and a display unit structured to display a plurality of display images in order based on a plurality of display data produced by the cut-out displayed image producing unit, wherein the cut-out displayed image producing unit is structured to cut out a portion of the still image as well as shifts a cut-out region of the still image so as to cancel a changed amount of imaging angles between the still image data whose portion is to be cut-out and the previously cut-out still image data and a changed amount of a relative angle of the position of imaging the previously cut-out still image and the position of the still image whose portion is to be cut-out with respect to a subject to be imaged, during cutting out a second or later still image, wherein the changed amount of the imaging angles is specified based on angle information indicating the imaging angles and the changed amount, which are added to the saved still image data whose portion is to be cut-out and the previously cut-out saved still image data, and the changed amount of the relative angle is specified based on imaged position information indicating the imaged position and the changed amount, which are added to the saved still image data whose portion is to be cut-out and the previously cut-out saved still image data. - View Dependent Claims (5, 6)
