controlling each of the camera accessories, by a control signal received by the associated communication device, to project a light beam, from an associated light projector to a subject of the bullet-time photography;
aligning an imaging direction of each of the cameras according to a direction of the light beam projected by the light projector of the attached camera accessory; and
triggering the cameras to capture images of the subject, wherein triggering comprises receiving, by the communication device associated with the camera accessory of the attached camera, a trigger signal.
2. The method according to claim 1 , wherein the light beam is a collimated laser beam.
3. The method according to claim 1 , wherein the imaging direction of each of the 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 cameras according to the direction of the respective light beam further comprises:
aligning an orientation of the camera assemblies such that the respective light beams point to a reference position on the subject.
5. The method according to claim 1 , wherein triggering the cameras to capture the images of the subject further comprises:
triggering the cameras to capture the images of the subject simultaneously.
6. The method according to claim 1 , wherein triggering the cameras to capture the images of the subject further comprises:
triggering the cameras to capture the images of the subject sequentially.
7. The method according to claim 1 , wherein triggering the 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 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 camera accessory attached to, and communicatively coupled to a camera, to perform bullet-time photography, the camera accessory including an associated communication device, the camera accessory configured to:
receive control signals via the communication device;
transmit data in the attached camera to another device via the communication device;
project a light beam from an associated light projector to a subject of bullet-time photography based on to the received control signals;
align an imaging direction of the camera according to a direction of the light beam projected by the light projector of the attached camera accessory; and
trigger the camera to capture images of the subject, wherein triggering comprises receiving, by the communication device associated with the camera accessory of the attached camera, a trigger signal.
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 camera accessory 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 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 camera accessory 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 camera accessory attached to, and communicatively coupled to a camera, to perform bullet-time photography, the camera accessory including an associated communication device, with the camera accessory configured to:
receive control signals via the communication device;
transmit data in the attached camera to another device via the communication device;
project a light beam from an associated light projector to a subject of bullet-time photography subject to the received control signals;
align an imaging direction of the camera according to a direction of the light beam projected by the light projector of the attached camera accessory; and
trigger the camera to capture images of the subject, wherein triggering comprises receiving, by the communication device associated with the camera accessory of the attached camera, a trigger signal.
