Abstract

An electronic imaging system that works in combination with an off-the-film (OTF) metering system intended for photographic film is described. The imaging system includes a combination of anti-reflection coatings, diffuse reflective coatings, and light absorbing coatings to control the reflections from the imaging system and thereby reduce reflections what would cause the OTF metering system to produce a false reading. The coatings are applied to the image sensor package and other surrounding components having high reflection properties. The geometrical arrangement and relative combinations of these reflectance-modifying treatments can be tailored to the particular geometry of the OTF metering system as well as the sensor and electronic component placement in the electronic imager system.
