Image joining apparatus, image joining method, and image joining program

摘要

Provided is an image joining apparatus that creates a joined image by joining multiple consecutive still images on a time axis, the image joining apparatus including: a past image confirmation unit that confirms whether there is a past still image located before the previous still image in terms of time in at least a part of a portion to be joined to the target still image; an angle calculation unit that calculates an angle formed between a motion vector associated with the target still image and a motion vector associated with the past still image, when the past image confirmation unit has confirmed that the past still image is present; and a stop processing unit that stops joining of the target still image when the angle calculated by the angle calculation unit is equal to or greater than a predetermined angle.

主权项

1. An image joining apparatus that creates a joined image by joining a plurality of consecutive still images on a time axis, the still images constituting a moving image, the image joining apparatus comprising:
an image sensor that captures the plurality of still images; and at least one processor that performs an image joining method by executing a computer program, the image joining method comprising:
a motion vector derivation step of deriving a motion vector between a target still image and a previous still image among the plurality of still images captured by the image sensor, the previous still image being adjacent to the target still image on the time axis;a time recording step of recording a time of the target still image within the moving image;a past image confirmation step of confirming whether there is a past still image located before the previous still image in terms of time in at least a part of a portion to be joined to the target still image;a time calculation step of calculating a time difference between a time of the past still image within the moving image and a time of the target still image within the moving image, when it is confirmed in the past image confirmation step that the past still image is present in at least a part of the portion to be joined;a stop processing step of stopping joining of the target still image when the time difference calculated in the time calculation step is equal to or greater than a predetermined time difference; anda joining processing step of joining the target still image when it is confirmed in the past image confirmation step that the past still image is not present in at least a part of the portion to be joined, or when the time difference calculated in the time calculation step is less than the predetermined time difference.
