a Universal Serial Bus (USB) interface configured to connect the camera accessory to the camera; and
a communication device configured to receive control signals from a controller and transmit data in the camera to another device;
projecting the light beam from each of the plurality of camera accessories to the subject;
aligning an imaging direction of each of the plurality of cameras according to a direction of the respective light beam; and
triggering the plurality of cameras to capture images of the subject.
2. The method according to claim 1 , wherein each light beam is a collimated laser beam.
3. The method according to claim 1 , wherein the imaging direction of each of the plurality of cameras is parallel to the direction of the respective light beam.
4. The method according to claim 1 , wherein aligning the imaging direction of each of the plurality of cameras according to the direction of the respective light beam further comprises:
aligning an orientation of each of the plurality of camera assemblies such that the respective light beam points to a reference position on the subject.
5. The method according to claim 1 , wherein triggering the plurality of cameras to capture the images of the subject further comprises:
triggering the plurality of cameras to capture the images of the subject simultaneously.
6. The method according to claim 1 , wherein triggering the plurality of cameras to capture the images of the subject further comprises:
triggering the plurality of cameras to capture the images of the subject sequentially.
7. The method according to claim 1 , wherein triggering the plurality of cameras to capture the images of the subject further comprises:
before the images of the subject are captured, setting an operation parameter for each of the plurality of cameras.
8. The method according to claim 7 , wherein the operation parameter is at least one of a shutter speed, an ISO, or an aperture of the respective camera.
9. A system for bullet-time photography, comprising:
a controller; and
a camera accessory attached to a camera, the camera accessory comprising:
a light projector configured to project a light beam to a subject of the bullet-time photography, wherein an imaging direction of the camera is aligned according to a direction of the light beam;
a first Universal Serial Bus (USB) interface configured to connect the camera accessory to the camera; and
a communication device configured to receive control signals generated by the controller and transmit data in the camera to another device;
wherein the controller is configured to:
control the light projector to project the light beam; and
trigger the camera to capture images of the subject when the subject starts an action.
10. The system according to claim 9 , wherein the light projector is a laser pointer configured to generate a collimated laser beam.
11. The system according to claim 9 , wherein the direction of the light beam is parallel to the imaging direction of the camera.
12. The system according to claim 9 , wherein the controller is further configured to align an orientation of the camera such that the light beam projected by the light projector points to a reference position on the subject.
13. The system according to claim 9 , wherein the communication device further comprises a second Universal Serial Bus (USB) interface.
14. The system according to claim 9 , wherein the communication device further comprises a wireless transceiver.
15. The system according to claim 9 , further comprising:
a base member attached to the camera, the base member configured to allow adjustment of an orientation of the camera.
16. The system according to claim 9 , wherein the controller is further configured to control an operation parameter of the camera.
17. The system according to claim 16 , wherein the operation parameter is at least one of a shutter speed, an ISO, or an aperture of the camera.
18. A system for bullet-time photography, comprising:
a camera;
a controller; and
a camera accessory attached to the camera, the camera accessory comprising:
a light projector configured to project a light beam to a subject of the bullet-time photography, wherein an imaging direction of the camera is aligned according to a direction of the light beam;
a Universal Serial Bus (USB) interface configured to connect the camera accessory to the camera; and
a communication device configured to receive control signals generated by the controller and transmit data in the camera to another device;
wherein the controller is configured to:
control the light projector to project the light beam; and
trigger the camera to capture images of the subject when the subject starts an action.
