Abstract
A camera and a method for controlling the camera. Also a face recognition secure access camera and a method of capturing an image that is not saturated or too dark.
Claims32
A camera comprising:
- a. a body;
- b. an image detector for capturing a target image housed in said body, said image detector having a digital signal output;
- c. a video digital signal processor connected to said image detector for camera control and processing said digital signal output wherein said image detector and said digital processor are adjacent to each other and housed in said camera body;
- d. an operating system for controlling camera functions;
- e. a first permanent memory means connected to said video digital signal processor for storing said operating system;
- f. a second removable memory means connected to the video digital signal processor for retrievably storing a plurality of images.

A method of camera control comprising the steps of:
- a. providing a camera control loop consisting of a first exposure control loop for a first side of the face of a target image and a second exposure control loop for the second side of the face of a target image;
- b. using the camera, acquire a target image;
- c. acquiring the face of the target image;
- d. capture a first image of the face;
- e. using the first exposure control loop measuring the average intensity of the pixels on a first side of said face;
- f. comparing measured intensity to a predetermined set point;
- g. adjusting camera exposure levels so that measured intensity meets said predetermined set point;
- h. capturing a second image of the face;
- i. using the second exposure control loop measuring the average intensity of the pixels on the side of said second image of the face opposite to that measured on the first image;
- j. comparing measured intensity to a predetermined set point;
- k. adjusting camera exposure levels so that the measured average intensity meets a predetermined set point;
- l. merging the output of said first and second exposure control loops into one image using an image merging method.

A method of authorized personnel identity authentication using face recognition and using a camera comprising:
- a body;
- an image detector for capturing a target image said image detector having a digital signal output;
- a video digital signal processor connected to said image detector for camera control and processing said digital output wherein said image detector and said digital processor are adjacent to each other and contained in said camera body;
- a first permanent memory means connected to said video digital signal processor for storing said operating system;
- a second removable memory means connected to said first digital processor for retrievably storing a plurality of images;
- comprising the steps of:
- a. placing a plurality of cameras at locations where personnel authentication using face recognition is required;
- b. connecting said plurality of cameras in a networked configuration;
- c. connecting said networked configuration to a central processing unit wherein said central processing unit includes a database of a plurality of images of authorized personnel;
- d. capturing the image of an authorized person;
- e. transmitting said image to said central processing unit by the network;
- f. verifying the image as the image of an authorized person.

A method of surveillance of restricted areas using face recognition and using a camera comprising:
- a body;
- an image detector for capturing a target image said image detector having a digital signal output;
- a video digital signal processor connected to said image detector for camera control and processing said digital signal output wherein said image detector and said digital processor are adjacent to each other and contained in said camera body;
- a first permanent memory means connected to said digital processor for storing said operating system;
- a second removable memory means connected to said first digital processor for retrievably storing a plurality of images, comprising the steps of:
- a. placing a plurality of cameras at locations where personnel authentication using face recognition is required;
- b. connecting said plurality of cameras in a networked configuration;
- c. connecting said networked configuration to a central processing unit wherein said central processing unit;
- d. capturing the facial image of a person entering the restricted area;
- e. transforming said captured image to a digital format;
- f. indexing the captured image for time and location;
- g. transmitting said image to said central processing unit by the network;
- h. storing the image for subsequent retrieval.
