Abstract

Claims (41)

1. An information processing device comprising:

a memory in which instructions are stored; and

at least one processor configured to execute the instructions to perform processing including:

receiving a captured image;

acquiring information related to a progress status of an event held in a place where the captured image has been captured;

determining a processing mode for the captured image based on the progress status of the event;

executing processing for the captured image corresponding to the processing mode,

wherein the processing mode for the captured image comprises performing:

performing face authentication on each of a plurality of persons in the captured image to determine whether any of the persons matches a previously registered person;

in response to determining that none of the persons match the previously registered person, displaying the captured image in a predetermined window on a display device such that the captured image entirely occupies the predetermined window;

in response to determining that one or more of the persons match the previously registered person:

displaying the captured image in a first portion of the predetermined window on the display device such that the captured image entirely occupies just the first portion of the predetermined window and such that a part of the captured image including the one or more persons matching the previously registered person is visibly identified;

displaying the part of the captured image including the one or more persons matching the previously registered person in a second portion of the predetermined window larger than the first portion and entirely occupying the predetermined window except for the first portion, such that the one or more persons are highlighted and such that a face of each of the one or more persons is visibly identified.

2. The information processing device according to claim 1 , wherein the processing includes:

detecting a number, a kind and motion of persons based on the captured image; and

acquiring the information related to the progress status of the event from the detected number, kind and motion of the person.

3. The information processing device according to claim 1 , wherein the processing includes:

acquiring the information related to the progress status of the event, including a timetable, a period of time elapsed after start of the event, and motion of persons in the captured image;

detecting whether the event has not been held, has ended, or is being held.

4. An information processing method performed by a computer and comprising:

receiving a captured image;

acquiring information related to a progress status of an event held in a place where the captured image has been captured;

determining a processing mode for the captured image based on the progress status of the event;

executing processing for the captured image corresponding to the processing mode,

wherein the processing mode for the captured image comprises performing:

performing face authentication on each of a plurality of persons in the captured image to determine whether any of the persons matches a previously registered person;

in response to determining that none of the persons match the previously registered person, displaying the captured image in a predetermined window on a display device such that the captured image entirely occupies the predetermined window;

in response to determining that one or more of the persons match the previously registered person:

displaying the captured image in a first portion of the predetermined window on the display device such that the captured image entirely occupies just the first portion of the predetermined window and such that a part of the captured image including the one or more persons matching the previously registered person is visibly identified;

displaying the part of the captured image including the one or more persons matching the previously registered person in a second portion of the predetermined window larger than the first portion and entirely occupying the predetermined window except for the first portion, such that the one or more persons are highlighted and such that a face of each of the one or more persons is visibly identified.

5. A non-transitory computer-readable storage medium storing a program executable by an information processing device to perform processing comprising:

receiving a captured image;

acquiring information related to a progress status of an event held in a place where the captured image has been captured;

determining a processing mode for the captured image based on the progress status of the event;

executing processing for the captured image corresponding to the processing mode,

wherein the processing mode for the captured image comprises performing:

performing face authentication on each of a plurality of persons in the captured image to determine whether any of the persons matches a previously registered person;

in response to determining that none of the persons match the previously registered person, displaying the captured image in a predetermined window on a display device such that the captured image entirely occupies the predetermined window;

in response to determining that one or more of the persons match the previously registered person:

displaying the captured image in a first portion of the predetermined window on the display device such that the captured image entirely occupies just the first portion of the predetermined window and such that a part of the captured image including the one or more persons matching the previously registered person is visibly identified;

displaying the part of the captured image including the one or more persons matching the previously registered person in a second portion of the predetermined window larger than the first portion and entirely occupying the predetermined window except for the first portion, such that the one or more persons are highlighted and such that a face of each of the one or more persons is visibly identified.
