Abstract

The present invention relates to a sighting device ( 1 ) providing an automatically updated reticule. The control unit ( 4 ) acquires the output level of the encoder ( 22 ) and calculates the expected distance between the dots of the reticule accordingly. The control unit ( 4 ) calculates the expected distance between the dots of the reticule and draws the reticule generated for that specific zoom level on the display means ( 3 ).

First claim

The invention claimed is:

1. A sighting device comprising;
at least one imaging means which acquires images from a scene to be watched comprising at least one zooming means which enables a user to change a level of magnification according to the users' preferences;
at least one display means which displays the scene viewed by the imaging means;
at least one control unit comprising a processor which calculates a shooting distance between neighboring dots of the display means and places a reticule over the scene being displayed at the display means;
wherein the imaging means further comprises at least one encoder enabling a magnification level of the zooming means to be determined;
wherein the control unit which comprises a processor and acquires an output level of the encoder and calculates the shooting distance between the neighboring dots of the display means according to following formula:

D
=

(

A
×
360

)

(

6400
×
n

)

wherein A is a horizontal resolution value of the display means, n is an angle of view and D is a distance between the dots of the reticule according to an acquired output level of the encoder.

2. The sighting device according to claim 1 , wherein the zooming means is utilized by turning a ring (zoom ring) manually or by means of a motor attached to the ring.

3. The sighting device according to claim 1 , wherein the zooming means provide continuous zoom.

4. The sighting device according to claim 1 , wherein the encoder is analog.

5. The sighting device according to claim 1 , wherein the encoder is digital.

6. The sighting device according to claim 5 , wherein the output of the encoder is a binary number that refers to the position of the encoder thus and the zooming means.

7. The sighting device ( 1 ) according to claim 5 , wherein the output of the encoder is peaks which are acquired while the zoom ring turns.

8. The sighting device according to claim 7 , wherein the control unit comprises a processor which counts the peaks outputted by the encoder and calculates the position of the encoder and the position of the zooming means.

9. The sighting device according to claim 2 , wherein the zooming means provide continuous zoom.

10. The sighting device according to claim 2 , wherein the encoder is analog.

11. The sighting device according to claim 3 , wherein the encoder is analog.

12. The sighting device according to claim 9 , wherein the encoder is analog.

13. The sighting device according to claim 2 , wherein the encoder is digital.

14. The sighting device according to claim 3 , wherein the encoder is digital.

15. The sighting device according to claim 9 , wherein the encoder is digital.
