Camera system and method for inspecting and/or measuring objects

A method for inspecting and/or measuring objects using a camera system, the camera system comprising:

• a color image sensor;
• an objective arrangement in front of the color image sensor for imaging an object from the environment on the color image sensor;
• at least one taking illumination light source with which the environment can be illuminated by non-monochromatic light;
• and
• at least one internal reference illumination light source which is arranged such that the color image sensor can be illuminated by it without the light irradiated by it passing through the objective arrangement, the method comprising the steps of.
• cyclically taking intermediate images or intermediate part images during operation under illumination of the color image sensor only by the at least one internal reference illumination light source and without illumination by the at least one taking illumination light source;
• and
• putting into relation the intermediate images or intermediate part images with images which are taken under illumination by the at least one taking illumination light source in order to correct aging and temperature effects of the at least one taking illumination light source.

A method for inspecting and/or measurement objects, in which a camera system comprising:

• a color image sensor;
• an objective arrangement in front of the color image sensor for imaging an object from the environment on the color image sensor;
• at least one taking illumination light source with which the environment can be illuminated by non-monochromatic light;
• and
• at least one internal reference illumination light source which is arranged such that the color image sensor can be illuminated by it without the light irradiated by it passing through the objective arrangement;
• is used to carry out the following steps, comprising:
• (i) taking an image of a known reference object under illumination by the at least one taking illumination light source;
• (ii) taking an image of the known reference object without illumination;
• and
• (iii) taking an image only under illumination by the at least one internal reference illumination light source before the operation.
