High speed dome camera with optic-electric slip ring arrangement
First Claim
1. A high speed dome camera, comprising:
- a stationary unit which comprises a shell and a base stationary mounted within said shell;
a moving unit which comprises a camera block, a motor supported within said camera block, and an image capturer driven to be rotated by said motor for capturing an image signal; and
an optic-electric slip ring arrangement coupling between said moving unit and said stationary unit.

Abstract
A high speed dome camera includes a stationary unit, a moving unit including an image capturer for capturing an image signal, and an optic-electric slip ring arrangement provided between the moving unit and the stationary unit which includes an electric unit for power transmission, and an optical unit for transmitting the image signal from the moving unit to the stationary unit when the image capturer is driven to rotate in a high rotational speed. The optic-electric slip ring arrangement prevents the reduction of the quality of the high definition transmission, so that the present invention has the advantages of the higher transmitting speed, broader signal band, less signal distortion, and higher reliability, so as to increase the rotational speed.

12. A method of internally transmitting an image signal of a high speed dome camera which comprises a stationary unit and a moving unit, comprising the steps of:
-
(a) capturing said image signal by an image capturer of said moving unit, wherein said image capturer is driven to be rotated in a high rotational speed during image capturing; (b) converting said image signal into an optical signal; (c) transmitting said optical signal from said moving unit to said stationary unit through an optic-electric slip ring arrangement provided between said stationary unit and said moving unit; and (d) converting said optical signal back to said image signal at said stationary unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
