Abstract
An image processing apparatus generates a predetermined evaluation value from a current frame image of a moving image or a combined image by combining a plurality of frame images of the moving image. The image processing apparatus generates the evaluation value from the combined image if a previous evaluation value is smaller than a threshold, and from the current frame image if the previous evaluation value is larger than or equal to the threshold.
Claims10
An image processing apparatus comprising:
- one or more processors that execute a program and, when executing the program, operate as:
- a combining unit configured to generate a combined image by combining a plurality of frame images of a moving image that include a current frame image;
- a selecting unit configured to selectively output the current frame image or the combined image;
- and
- a generating unit configured to generate a predetermined evaluation value from the image that is output by the selecting unit,
- wherein the generating unit controls the selecting unit to output the combined image if the generated evaluation value is smaller than a threshold, and output the current frame image if the evaluation value is larger than or equal to the threshold.
An image capture apparatus comprising:
- an image sensor for shooting a moving image;
- and
- an image processing apparatus that processes a moving image shot using the image sensor, wherein the image processing apparatus comprises:
- one or more processors that execute a program and, when executing the program, operate as:
- a combining unit configured to generate a combined image by combining a plurality of frame images of a moving image that include a current frame image;
- a selecting unit configured to selectively output the current frame image or the combined image;
- and
- a generating unit configured to generate a predetermined evaluation value from the image that is output by the selecting unit,
- wherein the generating unit controls the selecting unit to output the combined image if the generated evaluation value is smaller than a threshold, and output the current frame image if the evaluation value is larger than or equal to the threshold.
An image processing method that is executed by an image processing apparatus, comprising:
- generating a combined image by combining a plurality of frame images of a moving image that include a current frame image;
- outputting the current frame image or the combined image selectively;
- and
- generating a predetermined evaluation value from the image that is outputted by the outputting,
- wherein, in the outputting, the combined image is output if the evaluation value is smaller than a threshold, and the image of the current frame is output if the evaluation value is larger than or equal to the threshold.
A non-transitory computer-readable medium that stores a program for causing a computer to function as an image processing apparatus comprising:
- a combining unit configured to generate a combined image by combining a plurality of frame images of a moving image that include a current frame image;
- a selecting unit configured to selectively output the current frame image or the combined image;
- and
- a generating unit configured to generate a predetermined evaluation value from the image that is output by the selecting unit,
- wherein the generating unit controls the selecting unit to output the combined image if the generated evaluation value is smaller than a threshold, and output the current frame image if the evaluation value is larger than or equal to the threshold.
