## Abstract

There is a need to provide a color measuring position provision system and a color measuring position provision method capable of easily and reliably providing a user with a color measurement position on a printed matter without placing a measurement position provision guide on the printed matter. A color measuring position provision system includes: a color measurement position specifier that specifies a color measurement position on a printed matter; and a controller functioning as an object extractor that extracts a marker object candidate to perform color measurement at the color measurement position specified by the color measurement position specifier. The system extracts, as the marker object candidate, an object having a feature specifiable by a user during color measurement and provides the extracted object for a user.

## Claims

### Claim 1

A color measuring position provision system comprising:
a color measurement position specifier that specifies a color measurement position on a printed matter; and
an object extractor that extracts a marker object candidate to perform color measurement at the color measurement position specified by the color measurement position specifier,
wherein the object extractor extracts, as the marker object candidate, an object having a feature specifiable by a user during color measurement; and
wherein an object extracted by the object extractor is provided for a user.

### Claim 2 (depends on 1)

The color measuring position provision system according to claim 1,
wherein the object extractor extracts, as the marker object candidate, an object within reach of a guide rail of the manual color measuring instrument from the color measurement position out of candidates such as an object capable of being aligned with a guide rail of a manual color measuring instrument, an edge of a character and an image object, and one side of an image object aligned with a guide slit of the guide rail.

### Claim 3 (depends on 2)

The color measuring position provision system according to claim 2,
wherein the object extractor extracts an object that belongs to a candidate extracted as the marker object and includes the color measurement position on a straight line concatenating candidates.

### Claim 4 (depends on 3)

The color measuring position provision system according to claim 3,
wherein, when a plurality of the marker objects are extracted, the object extractor automatically settles the marker object out of a plurality of objects.

### Claim 5 (depends on 3)

The color measuring position provision system according to claim 3,
wherein the object extractor settles the marker object based on a priority such as one of a color difference capable of edge detection available to an object near the color measurement position during color measurement, the color measurement position available between the marker objects, and the marker object being nearest to the color measurement position.

### Claim 6 (depends on 3)

The color measuring position provision system according to claim 3,
wherein, when a plurality of the marker objects are extracted, the object extractor settles the marker object selected by a user from a plurality of objects.

### Claim 7

A color measuring position provision method comprising:
specifying a color measurement position, when available, on a printed matter;
extracting a marker object candidate to perform color measurement at the specified color measurement position and notifying a user of the marker object candidate; and
extracting, as the marker object candidate, an object having a feature specifiable by a user during color measurement.
