Abstract

A method for testing cameras includes positioning a camera such that an image of a target is displayed on a monitor within at least one default image parameter. The method further includes engaging a dimming condition of a light source from the camera, thereby generating a lighting condition signal. Subsequently the camera receives the lighting condition signal and displays it on the monitor. A group of observers then analyze the lighting condition signal. The method continues through engaging a second dimming condition of the light source from the first camera, thereby generating a second lighting condition signal, which is also displayed on the monitor. The group of observers then analyzes the second lighting condition signal.

Dependent claims

A camera testing system comprising:

a first target:
a first light source adapted to generate a first light signal;
a first camera aligned a remote distance from said first target, said first camera adapted to receive said first light signal;
a second target substantially aligned with said first camera;
a first dimming component adapted to engage a first dimming operation to dim said first light signal thereby generating a first lighting condition signal, said first dimming component further adapted to engage a second dimming operation to dim said first light signal thereby generating a second lighting condition signal;
and
a monitor adapted to receive said first lighting condition signal and said second lighting condition signal, said monitor further adapted to consecutively display said first lighting condition signal and said second lighting condition signal substantially within at least one default image parameter.
