Abstract

The embodiments of the present disclosure disclose a video playback apparatus and a video playback method. The video playback apparatus includes: an image sensor, a plurality of strip-shaped displays arranged in a first direction, and a processor connected to each of the strip-shaped displays and the image sensor, respectively, wherein the strip-shaped displays are configured to display information for associated items; the image sensor is configured to acquire image information for a user who moves in the first direction and a direction opposite to the first direction and browses the associated items; and the processor is configured to dynamically control display brightness of the plurality of strip-shaped displays according to the image information for the user, wherein brightness of one of the strip-shaped displays close to the user is greater than brightness of another one of the strip-shaped displays away from the user.

First claim

We claim:

1. A video playback apparatus, comprising:
an image sensor,
a plurality of strip-shaped displays arranged in a first direction, and
a processor connected to each of the strip-shaped displays and the image sensor, respectively,
wherein the strip-shaped displays are configured to display information for associated items, the information comprising at least names and prices of the associated items;
wherein the image sensor is configured to acquire image information for the plurality of strip-shaped displays, and to acquire image information for a user who is watching one or more of the strip-shaped displays; and
wherein the processor is configured to dynamically control display brightness of the plurality of strip-shaped displays according to the image information for the user,
wherein there are a plurality of image sensors arranged in a second direction parallel to the first direction,
wherein each of the plurality on image sensors is arranged between its adjacent strip-shaped displays,
wherein the image information for the user comprises a moving direction of the user,
wherein each of the image sensors is further configured to determine whether there is a user in a captured picture; and
wherein the processor is further configured to, when one of the image sensors determines that there us no user in a captured picture, turn off the image sensor, and when one of the image sensors determine that there is a user in a captured picture, acquire the moving direction of the user, so as to sequentially turn on the image sensors arranged in the second direction when the moving direction of the user is same as the first direction.

2. The video playback apparatus according to claim 1 , wherein the image information for the user comprises a watching direction of the user;
wherein each of the image sensors is further configured to detect the face of a user when the image information for the user is captured in real time; and
wherein the processor is further configured to acquire the watching direction of the user when one of the image sensors detects the face, so as to increase brightness of the strip-shaped displays corresponding to the watching direction of the user.

3. The video playback apparatus according to claim 1 , wherein the plurality of strip-shaped displays comprise a first row of strip-shaped displays in the first direction and a second row of strip-shaped displays in the third direction parallel to the first direction, and the first row of strip-shaped displays comprising a plurality of first strip-shaped displays are arranged opposite to the second row of strip-shaped displays comprising a plurality of second strip-shaped displays,
wherein the plurality of image sensors comprise a first row of image sensors and a second row of image sensors, the first row of image sensors comprises a plurality of first image sensors, the second row of image sensors comprises a plurality of second image sensors, each of the first image sensors is located between adjacent, first strip-shaped displays, and each of the second image sensors is located between adjacent, second strip-shaped displays;
wherein the processor is further configured to turn on the first strip-shaped display close to one of the first image sensors when the face of the user is detected by the first image sensor, and turn on the second strip-shaped display close to one of the second image sensors when the face of the user is detected by the second image sensor.

4. The video playback apparatus according to claim 3 , wherein
the processor is further configured to turn off the first strip-shaped display close to one of the first image sensors and/or turn off the first image sensor when the face of the user is not detected by the first image sensor, and turn off the second strip-shaped display close to one of the second image sensors and/or turn off the second image sensor when the face of the user is not detected by the second image sensor.

5. The video playback apparatus according to claim 3 , wherein the plurality of first strip-shaped displays in the first row of strip-shaped displays correspond to the plurality of second strip-shaped displays in the second row of strip-shaped displays in a one-to-one manner, two of the first strip-shaped displays are provided between the adjacent first image sensors, two of the second strip-shaped displays are provided between the adjacent second image sensors, and the first image sensors provided between the first strip-shaped displays are provided alternately with respect to the second image sensors provided between the second strip-shaped displays.

6. The video playback apparatus according to claim 1 , further comprising: an entrance sensor disposed at an entrance in the first direction, wherein
the entrance sensor is configured to detect whether there is a user entering a monitoring range of the video playback apparatus; and
the processor is further configured to turn on one or more of the image sensors adjacent to the entrance sensor when the entrance sensor detects that there is a user entering the monitoring range of the video playback apparatus.

7. The video playback apparatus according to claim 6 , wherein the entrance sensor is an infrared sensor.

8. The video playback apparatus according to claim 6 , wherein an entrance image sensor is provided between the entrance sensor and the first strip-shaped display closest to the entrance sensor.

9. The video playback apparatus according to claim 6 , further comprising: an exit sensor disposed at an exit of a watching passage, wherein
the exit sensor is configured to detect whether the user leaves the monitoring range of the video playback apparatus; and
the processor is further configured to determine whether there is any user according to the number of users entering the monitoring range detected by the entrance sensor, the number of users leaving the monitoring range detected by the exit sensor, and capturing results of the image sensors, and if there is no user, turn off all of the strip-shaped displays, the image sensors, and the exit sensor.

10. The video playback apparatus according to claim 9 , wherein an exit image sensor is provided between the exit sensor and the first strip-shaped display closestto the exit sensor.

11. The video playback apparatus according to claim 1 , wherein each of the image sensors is further configured to detect whether there is a user in a captured picture thereof before the image sensor is turned off, and perform a turn-off operation when it is detected that there is no user, and remain in a turn-on state when it is detected that there is a user.

12. A video playback method performed by a video playback apparatus comprising an image sensor, a plurality of strip-shaped displays arranged in a first direction, and a processor connected to each of the strip-shaped displays and the image sensor, respectively, the method comprising:
driving the strip-shaped displays to display information for associated items which comprises at least names and prices of the associated items;
