## Abstract

A processor acquires an image in which a plurality of objects of interest appears and acquires a plurality of partial image areas in each of which an object of interest appears from the image. An operation acceptor accepts an operation by a user to specify a range of at least one of size or color density of an object of interest using a filter setter. The processor acquires a size or a value of color density of the object of interest in each partial image area and displays, among the partial image areas in the image, the partial image area of the object of interest having a size or a color density within the range specified by the operation by the user in a highlighted manner.

## Claims

### Claim 1

An image processing device, comprising
one or more processors configured to:
acquire an image in which a plurality of objects of interest appears;
acquire a plurality of partial image areas in each of which one of the objects of interest appears from the image;
accept an operation by a user to specify a range of at least one of size or color density of the object of interest; and
acquire a size or a value of color density of the object of interest in each of the partial image areas and display, among the partial image areas included in the image, the partial image area of the object of interest having a size or a color density within the range specified by the operation by the user in a highlighted manner.

### Claim 2 (depends on 1)

The image processing device according to claim 1,
wherein the one or more processors acquire a first image in which a plurality of the objects of interest appears and a second image in which a plurality of the objects of interest appears,
acquire, from each of the first image and the second image, a plurality of the partial image areas in each of which one of the objects of interest appears, and
perform matching between a plurality of the partial image areas included in the first image and a plurality of the partial image areas included in the second image with respect to the partial image area including the object of interest having a size or a color density within the range specified by the operation by the user among a plurality of the partial image areas included in the first image and the second image.

### Claim 3 (depends on 1)

The image processing device according to claim 1,
wherein the one or more processors cause an indicator specifying a range of at least one of size or color density of the object of interest to be displayed on a display, and
accept an operation by the user to set a value of a lower limit or an upper limit of at least one of size or color density of the object of interest, using the indicator.

### Claim 4 (depends on 1)

The image processing device according to claim 1, wherein the image is a medical image.

### Claim 5 (depends on 4)

The image processing device according to claim 4, wherein the medical image is an image in which skin of a person or an animal is captured, and the object of interest is a lesion candidate on skin of the person or the animal.

### Claim 6 (depends on 5)

The image processing device according to claim 5, wherein the size of the object of interest is diameter of a perfect circle equivalent to area of lesion candidate range in which the lesion candidate appears, diameter of a circumcircle of the lesion candidate range, or a maximum diameter of the lesion candidate range.

### Claim 7 (depends on 5)

The image processing device according to claim 5, wherein color density of the object of interest is a luminance difference between inside and outside a lesion candidate range in which the lesion candidate appears.

### Claim 8

An image processing method, comprising
acquiring, by one or more processors, an image in which a plurality of objects of interest appears;
acquiring, by the one or more processors, a plurality of partial image areas in each of which one of the objects of interest appears from the image;
accepting, by the one or more processors, an operation by a user to specify a range of at least one of size or color density of the object of interest;
acquiring, by the one or more processors, a size or a value of color density of the object of interest in each of the partial image areas; and
displaying, by the one or more processors, among the partial image areas included in the image, the partial image area of the object of interest having a size or a color density within the range specified by the operation by the user in a highlighted manner.

### Claim 9

A system comprising a server and a device that include one or more processors,
wherein the system executes processing including:
acquiring an image in which a plurality of objects of interest appears;
detecting the objects of interest from the image and acquiring a plurality of partial image areas in each of which one of the objects of interest appears;
accepting an operation by a user to specify a range of at least one of size or color density of the object of interest; and
acquiring a size or a value of color density of the object of interest in each of the partial image areas and causing, among the partial image areas included in the image, the partial image area of the object of interest having a size or a color density within the range specified by the operation by the user to be displayed in a highlighted manner.
