Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope that is used to view an image of an object. A light shielding system shields light generated by a light source and transmitted to the endoscope and a stepping motor drives the light shielding system for a plurality of predetermined time intervals. A system detects a brightness of the image during each of the plurality of predetermined time intervals and an input system inputs one of a plurality of desired brightnesses of the image. A generating system generates a predetermined number of pulses during each of the plurality of predetermined time intervals, the predetermined number of pulses being transmitted to the stepping motor and a system determines an angular position of the light shielding system. A setting system sets one of a plurality of allowed brightness ranges of the image in response to the determined angular position of the light shielding system and a system determines whether the detected brightness is within the set one of the plurality of allowed brightness ranges.

Abstract: An optical sensing device for using light to locate objects or features in a field of view comprises a light source; a controllable lens having two states and being controllable between them, for example a multifocal lens having two or more foci for focusing light from the light source; and a sensor able to sense light reflected from an object, to determine information of the object. The use of two or more foci adds dynamic range to optical sensing to allow for reliable detection over a wide range of distances.
