Abstract

A control method of a display unit in a medical system, the control method including: acquiring an environmental image of the display unit; acquiring, according to the environmental image, feature information of at least one user therein; and determining a specific user of the at least one user according to the feature information so as to generate a control signal, the control signal being used to drive the display unit to rotate such that the specific user watches the display unit easily. The present invention also provides a control apparatus of a display unit in a medical system to implement the method.

First claim

The invention claimed is:

1. A method of controlling a display of a medical system, the method comprising:
acquiring an environmental image of an area surrounding the display;
acquiring, according to the environmental image, feature information of a plurality of users shown in the environmental image;
determining a specific user of the plurality of users according to the feature information to generate a control signal, the determining the specific user comprising:
obtaining first feature information and second feature information corresponding to the specific user from the feature information;
determining a watching requirement of the specific user based on the first feature information;
comparing the second feature information and preset information; and
determining the specific user of the plurality of users according to the comparison and watching requirement; and

generating a control signal for driving the display to rotate based on third feature information of the specific user.

2. The method according to claim 1 , wherein the feature information comprises facial information or eye information of the user.

3. The method according to claim 1 , wherein the control signal comprises a signal for driving the display unit to rotate by a certain angle.

4. The method according to claim 1 , wherein the preset information comprises priority information of different users, and
comparing the identified user with preset information comprises:
comparing the identified user with the priority information, and
determining a priority level of the user.

5. The method according to claim 4 , wherein the control signal is configured to:
drive the display unit to rotate by a certain angle towards the specific user having a high priority level.

6. The method according to claim 1 , wherein the first feature information comprises the eye information of the user; the second feature information comprises the facial information of the user.

7. The method according to claim 1 , wherein the preset information comprises priority information of different users;
comparing the user with preset information further comprises:
comparing the user with the priority information, and determining a priority level of the user.

8. The method according to claim 7 , wherein the control signal is configured to:
drive the display unit to rotate by a certain angle towards the specific user having a high priority level and having the watching requirement.

9. A control apparatus of a display unit in a medical system, the control apparatus comprising:
an environmental image generation unit;
a processing unit; and
a drive unit,
wherein the environmental image generation unit is used to generate an environmental image and transmit the environmental image to the processing unit; the processing unit is used to perform the method according to claim 1 so as to transmit a control signal to the drive unit; and
the drive unit is used to receive the control signal so as to drive the display unit to rotate.

10. A medical system, comprising the control apparatus according to claim 9 .

11. A non-transitory computer-readable storage medium for storing a computer program, wherein when executed by a computer, the computer program causes the computer to perform the control method according to claim 1 .

12. The method according to claim 1 , wherein generating the control signal comprises:
identifying a central point on the specific user;
determining a connecting line between the central point on the user and a central point on the display; and
determining a display rotation which reduces an angle between the connecting line an a perpendicular bisector of the display.
