Definitions
- the present invention relates to a method for synchronizing the recordings of two video cameras operated in parallel for the three-dimensional display of an image sequence, in particular two digital video recorders.
- the invention also relates to a system for implementing the method.
- Cameras are known in the field of professional film and video recordings which permit parallel recording of image sequences via two rectified lenses.
- the cameras and projectors are synchronized electronically and are correspondingly complex. Because of the high financial outlay, these systems are not suitable for private users, especially since appropriate training is required to operate the complex systems.
- the object of the present invention is to provide a method which allows synchronization of the recordings of two commercially available video chambers with high precision using simple and inexpensive means. It is also the object of the invention to create a system for implementing the method.
- An essential aspect of the invention is to introduce a light signal into the field of view of the two cameras running in parallel and optionally to record an acoustic signal, which is recorded by the cameras at the same time and which can be used during playback to synchronize the recordings.
- a common "filmic" flap is realized for both cameras. It is irrelevant whether one camera is the same with both cameras or whether a separate light signal is recorded with each camera. However, two light signals must occur simultaneously, which is the case two light-emitting diodes advantageously via a common voltage supply happens. When the recordings are later blended, the light signals are used as markers for the synchronization of the two films.
- the advantages of the invention lie in the possibility of simple and inexpensive implementation. With the invention it is possible to use commercially available video recorders for recording three-dimensional films. The synchronization is so precise that it creates a 3-D display with high quality.
- the invention makes 3-D recording interesting for the mass market. When using digital cameras playback on conventional PCs and television sets is possible. For the user, the invention offers the experience of plastic vision. This enables the 3-D effect without PC animation.
- the system according to the invention is then equipped with means which enable at least one temporary positioning of at least one light source in the field of view of both cameras. Both cameras can then be operated like one. It is particularly advantageous because it is inexpensive to implement the means via a pivotable holder, with which a light source is pivoted in front of both or at the same time one light source in front of each of the two objectives.
- the triggers of both chambers mechanically or electronically.
- the light sources are switched on when the common trigger is actuated. This ensures that when the film is later edited, the synchronization of both recordings is possible.
- control electronics that enable the two light sources to be switched on at the same time. It is particularly easy to implement the light sources with light-emitting diodes. These are available in any sizes, luminosity and colors and are particularly suitable for generating short-term light signals due to the low afterglow.
- the figure schematically shows two classic camcorders 1 with their lenses 2 and their electronics 3. Both are mounted on a common bracket, not shown. The image sequences recorded by the camcorders can be tapped via signal lines 4. According to the invention, both camcorders 1 are coupled via common control electronics 5, to which a common trigger 6 is connected.
- Means, not shown, are provided according to the invention, which make it possible to temporarily pivot a light-emitting diode 7 in front of each of the objectives 2.
- the LEDs 7 are also excited synchronously by the control electronics 5, to which they are connected via lines 8.
