Abstract

An information terminal includes acquiring an image of a first subject that is captured by a first sensor provided on a back surface of a surface on which a screen of the information terminal is disposed, and when displaying the image on the screen, changing a degree of scaling up/down of the image and a position at which the image is displayed in accordance with a position of a second subject that is imaged by a second sensor provided to the information terminal.

First claim

What is claimed is:

1. A non-transitory computer readable recording medium having stored therein an image processing program that causes an information terminal to execute a process comprising:
acquiring an image of a first subject that is captured by a first sensor provided on a back surface of a surface on which a screen of the information terminal is disposed; and
when displaying the image on the screen, changing a degree of scaling up/down of the image and a position at which the image is displayed in accordance with a position of a second subject that is imaged by a second sensor provided to the information terminal in order that the image of the first subject is superimposed onto a real first subject exposed over the screen.

2. The computer readable recording medium according to claim 1 , wherein the process further comprises:
by using a distance sensor that measures a distance, measuring a distance between the information terminal and the second subject; and
detecting the position of the second subject from the distance between the information terminal and the second subject.

3. The computer readable recording medium according to claim 1 , wherein the process further comprises:
by using a distance between characteristic points of a face acquired from an image of a face of a user of the information terminal captured by the second sensor, estimating a distance between the information terminal and the face of the user of the information terminal; and
estimating the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.

4. The computer readable recording medium according to claim 1 , wherein the process further comprises:
by using a size of the living body of a user of the information terminal acquired from the image captured by the first sensor, estimating a distance between the information terminal and a face of the user of the information terminal; and
estimating the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.

5. An image processing method comprising:
acquiring, by a processor, an image of a first subject that is captured by a first sensor provided on a back surface of a surface on which a screen of the information terminal is disposed; and
when displaying the image on the screen, changing, by the processor, a degree of scaling up/down of the image and a position at which the image is displayed in accordance with a position of a second subject that is imaged by a second sensor provided to the information terminal in order that the image of the first subject is superimposed onto a real first subject exposed over the screen.

6. The image processing method according to claim 5 , further comprising:
by using a distance sensor that measures a distance, measuring, by the processor, a distance between the information terminal and the second subject; and
detecting, by the processor, the position of the second subject from the distance between the information terminal and the second subject.

7. The image processing method according to claim 5 , further comprising:
by using a distance between characteristic points of a face acquired from an image of a face of a user of the information terminal captured by the second sensor, estimating, by the processor, a distance between the information terminal and the face of the user of the information terminal; and
estimating, by the processor, the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.

8. The image processing method according to claim 5 , further comprising:
by using a size of the living body of a user of the information terminal acquired from the image captured by the first sensor, estimating, by the processor, a distance between the information terminal and a face of the user of the information terminal; and
estimating, by the processor, the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.

9. An information terminal comprising:
a processor that executes a process comprising:
acquiring an image of a first subject that is captured by a first sensor provided on a back surface of a surface on which a screen of the information terminal is disposed; and
when displaying the image on the screen, changing a degree of scaling up/down of the image and a position at which the image is displayed in accordance with a position of a second subject that is imaged by a second sensor provided to the information terminal in order that the image of the first subject is superimposed onto a real first subject exposed over the screen.

10. The information terminal according to claim 9 , the process further comprises:
by using a distance sensor that measures a distance, measuring a distance between the information terminal and the second subject; and
detecting the position of the second subject from the distance between the information terminal and the second subject.

11. The information terminal according to claim 9 , the process further comprises:
by using a distance between characteristic points of a face acquired from an image of a face of a user of the information terminal captured by the second sensor, estimating a distance between the information terminal and the face of the user of the information terminal; and
estimating the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.

12. The information terminal according to claim 9 , the process further comprises:
by using a size of the living body of a user of the information terminal acquired from the image captured by the first sensor, estimating a distance between the information terminal and a face of the user of the information terminal; and
estimating the position of the second subject from the distance between the information terminal and the face of the user of the information terminal.
