Abstract

A telescope includes a main tube having an objective lens and an eyepiece, and a focuser located between the objective lens and the eyepiece; a mode switching mechanism located in front of the eyepiece and including an external switch lever and an internal flip mirror fixedly connected to the switch lever; a digital image store device located behind the main tube for receiving and processing incoming video and audio signals, storing the processed signals on a memory, and displaying the video signals on a liquid crystal display; and a focusing control device located between the main tube and the digital image store device. By operating the switch lever, optical axes of the telescope and the digital image store device can be brought to parallel with each other for the digital image store device to receive and record images exactly the same as those being viewed with the telescope.

Claims

1. A telescope, comprising:

a main tube being provided at front and rear ends with an objective lens and an eyepiece, respectively, both of which are formed from optical lenses, and at a position between said objective lens and said eyepiece with a focuser;

a mode switching mechanism substantially located in front of said eyepiece at a predetermined position;

a digital image store device located behind said mode switching mechanism; and

a focusing control device located between said main tube and said digital image store device but before said eyepiece; and

said mode switching mechanism being operable to cause optical axes of said telescope and said digital image store device to parallel with each other, such that said digital image store device is able to receive images exactly the same as those viewed at said eyepiece of said telescope, enabling said telescope to be used not only for observation but also recording from a distant location.

2. The telescope as claimed in claim 1, wherein said digital image store device includes an image sensor, a photoelectric signal converter, a shutter release, a liquid crystal display (LCD), a microphone, an analog-to-digital conversion circuit, a microprocessor, a memory, and a battery.

3. The telescope as claimed in claim 2, wherein said mode switching mechanism includes a switch lever fixedly connected to an outer end of a pivotal shaft so as to be externally accessible, and a flip mirror fixedly connected to an inner end of said pivotal shaft so as to internally locate in front of said eyepiece.

4. The telescope as claimed in claim 2, wherein said microphone of said digital image store device is capable of receiving incoming audio signals and transmitting said received audio signals to said analog-to-digital conversion circuit for converting said received audio signals into digital signals, said microprocessor is capable of receiving and processing said digital signals transmitted thereto by said analog-to-digital conversion circuit, and said memory is capable of storing said digital signals processed and transmitted thereto by said microprocessor.

5. The telescope as claimed in claim 3, wherein said switch lever of said mode switching mechanism is operable to switch said telescope between a first viewing mode, in which said flip mirror is turned to an inclination for reflecting an optical image of a distant target view to said eyepiece without displaying said optical image on said LCD of said digital image store device, and a second viewing mode, in which said flip mirror is turned to a flat position, so that said optical image of said distant target view is not reflected by said flip mirror but directly displayed on said LCD.

6. The telescope as claimed in claim 5, wherein said image sensor and said photoelectric signal converter of said digital image store device are capable of receiving and/or recording incoming video signals and said microphone of said digital image store device is capable of receiving and/or recording incoming audio signals when said telescope is switched to said second viewing mode, and wherein said received and/or recorded video and audio signals may be stored on said memory of said digital image store device.

7. The telescope as claimed in claim 6, wherein said video signals received by said image sensor are displayed on said LCD through driving of an image drive included in said digital image store device.

8. The telescope as claimed in claim 6, wherein said video signals received by said photoelectric signal converter are displayed on said LCD through driving of an image drive included in said digital image store device.

9. The telescope as claimed in claim 5, wherein said inclination for said flip mirror is within a range from 22.5 to 45 degrees.

10. The telescope as claimed in claim 2, wherein said LCD of said digital image store device is pivotally turnable up to 180 degrees.

11. The telescope as claimed in claim 7, wherein said image drive is a charge-coupled device (CCD) type image drive.

12. The telescope as claimed in claim 8, wherein said image drive is a complementary metal-oxide semiconductor (CMOS) type image drive.

13. The telescope as claimed in claim 7, wherein said image drive is programmable so as to show a sighting cross on said LCD when a corresponding program instruction is given to said image drive.

14. The telescope as claimed in claim 7, wherein said image drive is programmable so as to display said video signal on said LCD in a vertically or horizontally reversed position when a corresponding program instruction is given to said image drive.

15. The telescope as claimed in claim 7, wherein said image drive is programmable so as to adjust red, green and blue colors of said video signals displayed on said LCD when a corresponding program instruction is given to said image drive.

16. The telescope as claimed in claim 8, wherein said image drive is programmable so as to show a sighting cross on said LCD when a corresponding program instruction is given to said image drive.

17. The telescope as claimed in claim 11, wherein said image drive is programmable so as to show a sighting cross on said LCD when a corresponding program instruction is given to said image drive.

18. The telescope as claimed in claim 12, wherein said image drive is programmable so as to show a sighting cross on said LCD when a corresponding program instruction is given to said image drive.

19. The telescope as claimed in claim 8, wherein said image drive is programmable so as to display said video signal on said LCD in a vertically or horizontally reversed position when a corresponding program instruction is given to said image drive.

20. The telescope as claimed in claim 11, wherein said image drive is programmable so as to display said video signal on said LCD in a vertically or horizontally reversed position when a corresponding program instruction is given to said image drive.

21. The telescope as claimed in claims 12, wherein said image drive is programmable so as to display said video signal on said LCD in a vertically or horizontally reversed position when a corresponding program instruction is given to said image drive.

22. The telescope as claimed in claim 8, wherein said image drive is programmable so as to adjust red, green and blue colors of said video signals displayed on said LCD when a corresponding program instruction is given to said image drive.

23. The telescope as claimed in claim 11, wherein said image drive is programmable so as to adjust red, green and blue colors of said video signals displayed on said LCD when a corresponding program instruction is given to said image drive.

24. The telescope as claimed in claim 12, wherein said image drive is programmable so as to adjust red, green and blue colors of said video signals displayed on said LCD when a corresponding program instruction is given to said image drive.
