Optical observation apparatus with video device
First Claim
1. An optical observation apparatus including:
- an optical system (2) which produces an image of the object (1) being observed, and a video device (7) for recording the image and for producing an image signal representative of the image, characterised in that the video device (7) includes a first memory (71) for temporary storage of the image signal, a second memory (73) in data communication (77) with the first memory (71), and a control device (75) in control communication (76B, 76C) with both memories (71, 73) for controlling the storage procedure and data transfer from the first to the second memory, wherein the control device is adapted for controlling the storage procedure and the data transfer in such a way that overwriting of such data which are stored in the first memory (71) and which have already been stored a given period of time in the first memory is effected, and that transfer of the content of the first memory (71) to the second memory (73) takes place as a reaction to a trigger signal.

Abstract
An optical observation apparatus includes: an optical system which produces an image of an object being observed and a video device (7) for recording the image and producing an image signal. The video device (7) includes a first memory (71) for temporarily storing the image signal, a second memory (73) in data communication (77) with the first memory (71), and a control device (75) in communication (76A, 76B) with both memories (71, 73) for controlling the storage procedure in the first memory and data transfer from the first to the second memory. The control device (75) controls the storage procedure and the data transfer so that overwriting of such data already stored for a given period of time in the first memory (71) is effected and that transfer of the content of the first memory (71) to the second memory (73) takes place as a reaction to a trigger signal.
