Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to security camera devices and, more specifically, to a self contained image data analysis security camera containing logic circuits to capture an initial image and a processor to compare subsequent images thereto. The images are transmitted to a central station allowing the field of view to be displayed on a monitor and recorded by a VCR or other suitable recording device. The present invention may be used for conventional monitoring wherein streaming video is sent directly to the monitor and recording device without image comparison. When in security mode the processor in the camera continually compares incoming subsequent images with the initial captured image stored in the memory until a discrepancy between the two images is detected and initiates an alarm mode. A discrepancy between the initial captured image and an incoming subsequent image initiates an alarm mode wherein an audible and/or visual alarm is activated at the central station and/or other desired location. The alarm mode remains in effect until the operator depresses a memory control switch which then clears the memory and captures the current image which is then used for comparison to any subsequent images for the duration of the security mode or until another discrepancy is detected by the processor resulting in another alarm condition. 
   The present invention includes an alarm sensitivity adjustment means to the processor to allow the operator to determine how much of a discrepancy between the captured image and the stored image is required to initiate the alarm mode. For instance, a high sensitivity setting may initiate the alarm mode due to the movement of a fly or other small object, whereas the introduction of a cat into the field of view during a medium sensitivity setting would be required to have the processor set off the alarm and a low sensitivity setting would require the introduction or movement of a larger object such as human to initiate an alarm. 
   Additional options to the present invention include a power loss detection battery backup and connection less transmission of image signals, remote control switches, alarms and other appropriate remote components.

The camera  12  may be set in monitor mode wherein the image is sent directly to the monitor  14  and the recording device  16  or the operator  100  may capture an image thereby initiating the security mode wherein subsequent images are compared thereto. An alarm  18  will be activated if a deviation between the real time image and the sampled image stored in the memory is detected by the processor. The operator  100  determines the operation and function of the present invention from a remote location through the manipulation of user controls  36 . 
     FIG. 13  is an illustrative view of the present invention in use. Shown is the image data analysis security camera system of the present invention in use wherein the processor in the camera  12  has detected an image differentiation between the real time image and the captured image because an intruder  102  has entered the secured area and has initiated the alarm mode. An audible/visual alarm  18  has been activated and has alerted security personnel to the breach of the secured area. The image of the secured area is being transmitted to the monitor  14  and recording device  16  in the remote monitoring station. The present invention will remain in alarm mode until the operator  100  presses the memory control switch on the user controls  36  to clear the previously captured image and replace it with the current one thus returning the system to security mode. 
     FIG. 14  is an illustrative view of the user controls  36  including control switches  38 . The control switches  38  of the present invention are designed to be positioned and operated at the monitoring station. The switches  38  include a power and monitor switch  46 , an security mode switch  50 , an image capture switch  48 , a memory control switch  44  and an variable alarm sensitivity switch  40 . The variable alarm sensitivity switch  40  serves to allow the operator to adjust the degree of differentiation required to initiate the alarm mode. This is achieved through the use of a variable resistor or other such appropriate component suitable for the objective of the variable alarm sensitivity switch  40 . The variable alarm sensitivity switch  40  informs the processor how great a deviation between the captured image and the real time image is required to initiate an alarm condition. 
     FIG. 15  is an illustrative block diagram of the present invention  10 . The data image analysis security camera  12  of the present invention  10  may also be used with just an alarm  18  without a link to a monitor or a recording device. The data image analysis security camera  12  comprises a lens  24 , a light sensitive electronic chip  26 , a processor  28 , a memory  30 , a memory control circuit  32  and an image circuit  34 . The image data analysis security camera  12  is in communication with an external power source  42 , an audible and/or visual alarm  18 , user controls  36  including control switches  38  and a variable alarm sensitivity switch  40  based in a remote monitoring station  20 .
