Information processing device, information processing method, and information processing system

An information processing method, comprising:

• extracting identification (ID) information from a captured image of a superimposition image,
• wherein the superimposition image comprises a first image and the ID information superimposed on the first image for determination of one of admittance or non-admittance of entrance with an electronic ticket based on the ID information;
• and
• determining one of the admittance or the non-admittance of the entrance with the electronic ticket based on the electronic ticket stored in a memory and the ID information,
• wherein the superimposition image is provided by a gate display screen at an entrance,
• wherein the superimposition image is superimposed on the ID information that indicates time radiance variations on the first image,
• wherein the captured image is a second image of the superimposition image and captured by a focal-plane shutter system camera, and
• wherein the ID information is extracted based on spatial radiance variations on the captured image.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a computer, cause the computer to execute operations, the operations comprising:

• extracting identification (ID) information from a captured image of a superimposition image,
• wherein the superimposition image comprises a first a image and the ID information superimposed on the first image for determination of one of admittance or non-admittance of entrance with an electronic ticket based on the ID information;
• and
• determining one of the admittance or the non-admittance of the entrance with the electronic ticket based on the electronic ticket stored in a memory and the ID information,
• wherein the superimposition image is provided by a gate display screen at an entrance,
• wherein the superimposition image is superimposed on the ID information that indicates time radiance variations on the first image,
• wherein the captured image is a second image of the superimposition image and captured by a focal-plane shutter system camera, and
• wherein the ID information is extracted based on spatial radiance variations on the captured image.

An information processing system, comprising:

• a gate display screen configured to display a superimposition image, wherein the superimposition image contains a first image, and identification (ID) information superimposed on the first image and used for determination of one of admittance or non-admittance of entrance with an electronic ticket;
• and
• circuitry configured to:
• extract the ID information from a captured image of the superimposition image, and
• determine one of admittance or non-admittance of entrance with the electronic ticket based on the electronic ticket stored in a memory and the ID information,
• wherein the superimposition image is superimposed on the ID information that indicates time radiance variations on the first image,
• wherein the captured image is a second image of the superimposition image and captured by a focal-plane shutter system camera, and
• wherein the ID information is extracted based on spatial radiance variations on the captured image.
