Abstract
The information processing device photographs a certificate and determines its authenticity. The information processing device includes a photographing means and a determination means. The photographing means photographs a certificate and generates a photographed image. The determination means determines authenticity of the certificate based on appearance of a surface of the certificate in the photographed image. When the certificate is determined to be true, the image of the certificate is registered with the information processing device.
Claims19
An information processing device comprising:
- a camera;
- an acceleration sensor;
- a memory configured to store instructions;
- and
- one or more processors configured to execute the instructions to:
- cause the camera to photograph a certificate and generate a photographed image;
- and
- determine authenticity of the certificate based on appearance of a surface of the certificate in the photographed image,
- wherein the one or more processors are further configured to execute the instructions to:
- cause the acceleration sensor to output an output value of the acceleration sensor at a time of photographing the certificate by the camera,
- calculate a first inclination which is an inclination of a photographing direction of the camera with respect to the certificate based on the photographed image,
- calculate a second inclination which is an inclination of the photographing direction of the camera with respect to the certificate using the output value of the acceleration sensor, and
- compare the first inclination and the second inclination to determine the authenticity of the certificate.
An information processing method executed by an information processing device comprising a camera and an acceleration sensor, the method comprising:
- causing the camera to photograph a certificate and generating a photographed image;
- and
- determining authenticity of the certificate based on appearance of a surface of the certificate in the photographed image,
- wherein the determining the authenticity of the certificate comprises:
- causing the acceleration sensor to output an output value of the acceleration sensor at a time of photographing the certificate by the camera;
- calculating a first inclination which is an inclination of a photographing direction of the camera with respect to the certificate based on the photographed image;
- calculating a second inclination which is an inclination of the photographing direction of the camera with respect to the certificate using the output value of the acceleration sensor;
- and
- comparing the first inclination and the second inclination to determine the authenticity of the certificate.
A non-transitory computer-readable recording medium recording a program, the program causing a computer of an information processing device comprising a camera and an acceleration sensor to execute:
- causing the camera to photograph a certificate and generating a photographed image;
- and
- determining authenticity of the certificate based on appearance of a surface of the certificate in the photographed image,
- wherein the determining the authenticity of the certificate comprises:
- causing the acceleration sensor to output an output value of the acceleration sensor at a time of photographing the certificate by the camera;
- calculating a first inclination which is an inclination of a photographing direction of the camera with respect to the certificate based on the photographed image;
- calculating a second inclination which is an inclination of the photographing direction of the camera with respect to the certificate using the output value of the acceleration sensor;
- and
- comparing the first inclination and the second inclination to determine the authenticity of the certificate.
