Abstract

A motion detection and imaging method and device 10 for carrying out the method are provided. The device 10 comprises a housing 12 containing a CCD 18 for providing digital image data, a lens 16 for focusing an image on the CCD 18 and a solid state non-volatile memory 24 for storing the digital image data. In one embodiment, the device includes a motion detector 26 for triggering the storage of the digital data.

Claims

1. A motion detection and imaging device comprising a housing containing a CCD for providing digital image data, a wide-angle lens assembly for focusing an image to be observed on the CCD, a magnifying lens between the wide-angle lens assembly and the CCD and a solid state non-volatile memory for storing said digital image data.

2. The device according to claim 1, wherein the lens assembly includes an electronic shutter.

3. The device according to claim 2, further comprising means for controlling opening of the shutter at predetermined time intervals for intermittently focussing an image on the CCD.

4. A motion detection and imaging device comprising a housing containing a CCD for providing digital image data, a lens for focusing an image to be observed on the CCD, a solid state non-volatile memory for storing said digital image data and means for compressing the digital data prior to storage in the memory and means for decompressing the data after retrieval from the memory.

5. The device according to claim 4, further comprising an electronic clock and calendar for timing and dating the digital data.

6. A motion detection and imaging device comprising a housing containing a CCD for providing digital image data, a lens for focusing an image to be observed on the CCD, a solid state non-volatile memory for storing said digital image data and a motion detector for triggering the storage of the digital data in memory, wherein the housing is tamper resistant and has a transparent front and the lens and the motion detector are located adjacent the transparent front.

7. A motion detection and imaging method comprising the steps of focusing an image of an area being monitored on a CCD by means of a lens to provide digital image data, compressing the data by means of a suitable compression algorithm and storing the compressed data in a solid state non-volatile memory.

8. The method according to claim 7, wherein the image of the area being monitored is focussed on the CCD intermittently at predetermined time intervals to provide digital image data of a series of separate still pictures which is stored in said memory.

9. The method according to claim 7, further comprising the step of initiating the storage of the digital data by means of a motion detection device which detects movement in the area being monitored.

10. The method according to claim 7, wherein the lens comprises a wide angle lens assembly.

11. The method according to claim 7, further comprising the steps of measuring the light intensity in the area and illuminating the area if the light intensity is below a predetermined value.

12. A motion detection and imaging method comprising the steps of focusing an image of an area being monitored on a CCD by means of a wide-angle lens assembly to provide digital image data, including the step of placing a magnifying lens between the wide angle lens assembly and the CCD to capture the entire image from the wide angle lens assembly for the CCD and storing the data in a solid state non-volatile memory.
