## Abstract

There is disclosed an image processing apparatus including a hardware processor which generates a highly resolved still image from a plurality of frame images obtained by continuously imaging a moving subject. The hardware processor analyzes each of the plurality of frame images to calculate a feature amount, and determines, on a basis of the calculated feature amount, a reference frame image which becomes a reference when generating the highly resolved still image from the plurality of frame images.

## Claims

### Claim 1

An image processing apparatus comprising a hardware processor which generates a highly resolved still image from a plurality of frame images obtained by continuously imaging a moving subject, wherein the hardware processor analyzes each of the plurality of frame images to calculate a feature amount, and determines, on a basis of the calculated feature amount, a reference frame image which becomes a reference when generating the highly resolved still image from the plurality of frame images.

### Claim 2 (depends on 1)

The image processing apparatus according to claim 1, wherein the feature amount is a square error from a model image which becomes a model of the generated still image.

### Claim 3 (depends on 1)

The image processing apparatus according to claim 1, wherein the feature amount is a correlation coefficient with a model image which becomes a model of the generated still image.

### Claim 4 (depends on 1)

The image processing apparatus according to claim 1, wherein the plurality of frame images are a plurality of frame images obtained by continuously imaging a chest with radiation, and
the feature amount is an area of a lung field region.

### Claim 5 (depends on 1)

The image processing apparatus according to claim 1, wherein the plurality of frame images are a plurality of frame images obtained by continuously imaging a chest with radiation, and
the feature amount is a lower end position of a lung field region.

### Claim 6

An image processing method in an image processing apparatus which generates a highly resolved still image from a plurality of frame images obtained by continuously imaging a moving subject, the image processing method comprising:
analyzing each of the plurality of frame images to calculate a feature amount, and determining, on a basis of the calculated feature amount, a reference frame image which becomes a reference when generating the highly resolved still image from the plurality of frame images.

### Claim 7

A program causing a computer for use in an image processing apparatus which generates a highly resolved still image from a plurality of frame images obtained by continuously imaging a moving subject to perform, as a determiner, analyzing each of the plurality of frame images to calculate a feature amount, and determining, on a basis of the calculated feature amount, a reference frame image which becomes a reference when generating the highly resolved still image from the plurality of frame images.
