Information processing device and attendance state management method

1. An attendance management system comprising:

a camera provided in a classroom including a plurality of areas; and

an information processing device that is communicably connected with the camera,

wherein the camera performs a sequence process, in which the camera sequentially photographs the plurality of areas, and detects a face of a student in each of the plurality of areas,

the camera performs the sequence process a plurality of times during a class, and

the information processing device includes a processor that performs operations including:

receiving face image data of the student, who takes the class in the classroom, a plurality of times during the class from the camera provided in the classroom;

comparing the face image data with registered face image data of the student and count the number of times the student of the registered face image data is photographed by the camera during the class; and

transmitting the number of times of photographing to a terminal device used by a teacher who teaches the class,

wherein the processor further transmits unmatched face image data to the terminal device, the unmatched face image data being the face image data which does not match the registered face image data, and

after the processor transmits the unmatched face image data to the terminal device, when the processor receives a registration instruction from the terminal device, the processor registers the unmatched face image data as the registered face image data.

2. The attendance management system according to claim 1 ,

wherein the processor further transmits a time when the student of the registered face image data is photographed by the camera to the terminal device.

3. The attendance management system according to claim 1 ,

wherein the processor further transmits the face image data which matches the registered face image data to the terminal device.

4. The attendance management system according to claim 1 ,

wherein the class is taught a plurality of times during a certain period of time, and

the processor further counts the number of times of attendance of the class taught during the certain period of time for each student of the registered face image data.

5. The attendance management system according to claim 1 ,

wherein the processor further determines attendance of the student in the class in response to an instruction from the terminal device.

6. An attendance state management method performed by a camera provided in a classroom including a plurality of areas, and an information processing device that is communicably connected with the camera, the method comprising:

performing, by the camera, a sequence process, in which the camera sequentially photographs the plurality of areas in the classroom and detects a face of a student in each of the plurality of areas performing, by the camera, the sequence process a plurality of times during a class, wherein the sequence process includes,

receiving, by the information processing device, face image data of the student, who takes the class in the classroom, a plurality of times during the class from the camera provided in the classroom;

comparing, by the information processing device, the face image data with registered face image data of the student and counting the number of times the student of the registered face image data is photographed by the camera during the class;

transmitting, by the information processing device, the number of times of photographing to a terminal device used by a teacher who teaches the class;

transmitting, by the information processing device, unmatched face image data to the terminal device, the unmatched face image data being the face image data which does not match the registered face image data; and

registering, by the information processing device, the unmatched face image data as the registered face image data, when a registration instruction is received from the terminal device after transmitting the unmatched face image data to the terminal device.

7. A non-transitory computer readable storage medium on which a program for making a computer to execute an attendance state management method is stored,

the attendance state management method includes:

causing a camera to perform a sequence process, in which the camera sequentially photographs a plurality of areas in a classroom, and detects a face of a student in each of the plurality of areas,

causing the camera to perform the sequence process a plurality of times during a class,

receiving face image data of the student, who takes the class in the classroom, a plurality of times during the class from the camera provided in the classroom;

comparing the face image data with registered face image data of the student and counting the number of times the student of the registered face image data is photographed by the camera during the class;

transmitting the number of times of photographing to a terminal device used by a teacher who teaches the class;

transmitting unmatched face image data to the terminal device, the unmatched face image data being the face image data which does not match the registered face image data; and

registering the unmatched face image data as the registered face image data, when a registration instruction is received from the terminal device after transmitting the unmatched face image data to the terminal device.

8. The attendance management system according to claim 1 , further comprising

a memory that stores camera identification information identifying the camera and an interval time associated with each other,

wherein the camera sequentially photographs the plurality of areas at the interval time stored in the memory in the sequence process.

9. The attendance management system according to claim 1 , wherein the plurality of areas are set such that all seats where the student can sit are included.

10. The attendance management system according to claim 1 , wherein

the camera photographs one of the plurality of areas after photographing an other of the plurality of areas for a predetermined period of time.

11. The attendance management system according to claim 1 , wherein

the processor receives the face image data at least three times during the class from the camera,

when counting the number of times of photographing the student, the processor gives a higher weight for at least one of first and last times of the at least three times than a weight for a time other than the first and last times of the at least three times.
