Abstract

An image display apparatus includes: an image display unit that displays an image; a memory unit that stores, for each user, setting information related to the image display unit; an image capturing processing unit that generates image data based on a signal captured by an image capturing unit; an image analysis processing unit that extracts, from the image data generated by the image capturing processing unit, a determination image in which personal information for identifying a user is recorded, the image analysis processing unit reading the personal information from the extracted determination image; and a control unit that reads, from the memory unit, setting information corresponding to the user of the personal information read by the image analysis processing unit, the control unit controlling display of the image display unit based on the read setting information.

Claims

1. An image display apparatus comprising:

an image display unit that displays an image;

a memory unit that stores, for each user, setting information related to the image display unit;

an image capturing processing unit that generates image data based on a signal captured by an image capturing unit;

an image analysis processing unit that extracts, from the image data generated by the image capturing processing unit, a determination image in which personal information for identifying a user is recorded, the image analysis processing unit reading the personal information from the extracted determination image; and

a control unit that reads, from the memory unit, setting information corresponding to the user of the personal information read by the image analysis processing unit, the control unit controlling display of the image display unit based on the read setting information.

2. The image display apparatus according to claim 1, wherein

the image capturing unit is installed so as to capture an image of the user of the image display apparatus, and

the image analysis processing unit detects whether the user is present or away based on the image data, and extracts a determination image from the image data when presence of the user is detected.

3. The image display apparatus according to claim 2, wherein

the image capturing unit captures an image at predetermined intervals, and

the image analysis processing unit compares current image data with previous image data to thereby detect the user, extracts a feature point of the detected user, treats the user as being present while the feature point of the user is present in an image data captured by the image capturing unit, and treats the user as being away when the feature point of the user is not present in an image data captured by the image capturing unit.

4. The image display apparatus according to claim 2, wherein the control unit puts the image display apparatus into a power saving state when the user leaves, and releases the power saving state of the image display apparatus when the user is present.

5. The image display apparatus according to claim 2, further comprising a timing unit that measures time,

wherein the control unit writes into the memory unit a current time and date as a most recent time and date at which the user started using the image display apparatus when the user is detected as being present, and the control unit writes into the memory unit a current time and date as a time and date at which the user last used the image display apparatus when the user is detected as being away.

6. The image display apparatus according to claim 5, wherein

the memory unit stores for each user, a total used time which is a total amount of time the image display apparatus has been used for, and

when a user is detected as being away, the control unit updates the total used time of the user stored in the memory unit, based on a most recent time and date at which the user started using the image display apparatus and a time and date at which the user last used the image display apparatus.

7. An image display method comprising:

generating image data based on a signal captured by an image capturing unit, by an image capturing processing unit of an image display device comprising an image display unit that displays an image;

extracting, from the generated image data, a determination image in which personal information for identifying a user is recorded, and reading the personal information from the extracted determination image, by an image analysis processing unit of the image display device; and

reading setting information corresponding to the user of the read personal information, from a memory unit that stores, for each user, setting information related to the image display unit, and controlling display of the image display unit based on the read setting information, by a control unit of the image display device.
