Abstract: An imaging system includes a lighting controller for independently controlling emission of illumination light to be emitted by a light source in: (i) a non-all-line exposure period, which contains a reading period in which electrical signals are sequentially read out on a horizontal-line basis from an image sensor for one frame or one field period, and in which at least one horizontal line of the horizontal lines for the one frame or the one field period is not exposed to light, and (ii) in an all-line exposure period, in which all of the horizontal lines for the one frame or the one field period are exposed to light.

Abstract: A light source device includes a primary light source that emits primary light, a light guide that guides the primary light, an optical conversion unit that converts the primary light emitted from the light guide and having a first light distribution angle into secondary light having a second light distribution angle and emits the secondary light, and a light distribution adjustment unit that adjusts the secondary light to illumination light having a third light distribution angle and emits the illumination light. The light distribution adjustment unit and the optical conversion unit slide each other. The light distribution adjustment unit allows a light distribution adjustment amount for adjusting the second light distribution angle of the secondary light to adjust to the third light distribution angle of the illumination light.

Abstract: An imaging system includes an illumination portion, an imager, a reader, and an illumination controller configured to control an intensity of illumination light based on modulated illumination in a non-reading period. The modulated illumination has a first integrated light amount as a product of a variable intensity of a first pulse and an output period of the illumination light and a second integrated light amount as a product of a constant intensity of a second pulse and the output period. In the non-reading period, the illumination controller causes a predetermined light amount that is not larger than a maximum value of the first integrated light amount and is not smaller than a minimum value of the second integrated light amount to transit between the first integrated light amount and the second integrated light amount.

Abstract: A light source device includes a semiconductor light source that radiates light at a light quantity according to an applied current, a circuit that determines a current instruction value based on control information, first and second drive units, each of the units that is connected to the semiconductor light source and the circuit, and is capable of outputting, to the semiconductor light source, a current having magnitude corresponding to the current instruction value. The control information is set based on brightness of an image captured by an imaging element. When one of the first and second drive units is switched to the other, the circuit causes the other to start the current output after an elapse of a predetermined stop time period having a length at a predetermined ratio or less to a frame rate on the imaging element since a stop of the current output from the one.
