Method for calibration of an electronic camera
First Claim
1. A method for the calibration of an electronic camera located at a local site, comprising the steps of:
- (a) presenting an optical stimulus to the camera;
(b) acquiring at least one image of said optical stimulus by the camera;
(c) transmitting said at least one image via telecommunication means from said local site to a remote site; and
(d) evaluating said at least one image at said remote site.

Abstract
An electronic camera can be reprogrammed, recalibrated or optimized for a given application or environment by a remote expert who does not have to be present locally. The camera requires a bi-directional data path to the expert, preferably using the internet, for writing parameters into the camera'"'"'s program memory and for reading its acquired images. The remote expert must be capable of presenting selected visual stimuli to the camera, which are presented by a suitable image presentation device to the camera, under remote control by the expert. Thanks to the invention, a recalibration of the camera is more simple, faster, at lower costs and independent of the location of the camera user.

17. An arrangement for the calibration of an electronic camera, comprising
means for placing the camera located at a local site; -
an image presentation device located at a local site;
means for evaluating an image acquired by the camera, said image-evaluating means being located at a site remote from said local site;
means for determining parameters influencing the camera properties, depending on the evaluation of said image, said parameter-determining means being located at a site remote from said local site; and
bi-directional telecommunication means for connecting said local site and said remote site. - View Dependent Claims (18, 19, 20, 21, 22)

23. A data processing system for the calibration of an electronic camera, wherein said data processing system includes a display and an operating system, said data processing system comprising:
-
means for selecting an optical stimulus;
means for transmitting said optical stimulus via telecommunication means to the camera;
means for receiving via telecommunication means an image acquired by the camera;
means for evaluating said image;
means for determining parameters influencing the camera properties, depending on the evaluation of said image; and
means for transmitting said parameters via telecommunication means to the camera.

24. A computer readable medium, having a program recorded thereon, where the program is to make a computer execute procedure
to select an optical stimulus; -
to transmit said optical stimulus via telecommunication means to a camera;
to receive via telecommunication means an image acquired by the camera;
to evaluate said image;
to determine parameters influencing the camera properties, depending on the evaluation of said image; and
to transmit said parameters via telecommunication means to the camera.
