Abstract
An image-recording system having at least one camera, having a receiving device and having a signal connection between the camera and the receiving device. The receiving device generates a PWM-coded signal which is transmitted to the camera. A clock signal is obtained in the camera from the PWM-coded signal.
Claims13
An image-recording system comprising:
- at least one camera without an internal clock pulse oscillator;
- a receiving device;
- and
- at least one signal connection situated between the at least one camera and the receiving device,
- wherein the receiving device includes an arrangement for generating a PWM-coded signal,
- wherein the at least one signal connection is for transmitting the PWM-coded signal from the receiving device to the camera, and
- wherein the camera includes an arrangement for decoding the PWM-coded signal and for recovering a clock signal from the PWM-coded signal.
4 more elements
A method for controlling an image-recording system that includes a receiving device and at least one camera without an internal clock pulse oscillator, comprising:
- using the receiving device to generate a PWM-coded signal;
- feeding the signal to the camera via a signal connection;
- and
- regenerating a clock signal in the camera from the PWM-coded signal.
