DEFINITION

Classification: 396/155

WITH OBJECT ILLUMINATION FOR EXPOSURE:

(under the class definition) Subject matter having means to illuminate an object with artificial light (illumination means; e.g., a flash device) for exposure purposes in combination with a camera structure.

(1) Note. Exposure purposes include, for example, preexposure illumination for red-eye reduction, determining a proper exposure, or providing illumination when the shutter is open.

(2) Note. See "OBJECT ILLUMINA-TION SUBCOMBINATIONS" note under the main class definition for line notes with other classes.
