    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.

    Abstract: A first signal processing apparatus includes: an image processing unit configured to at least execute a composition process of generating composed image information in which first image information or second image information and textual information are superimposed; and a control unit configured to control the process of the image processing unit in accordance with communication with a second signal processing apparatus. The control unit selects either one of the first image information and the second image information, and when the second image information is selected, the control unit outputs a first command for instructing the second signal processing apparatus not to superimpose the second image information and the textual information related to the second image information, and causes the image processing unit to generate composite image information in which the second image information and the textual information related to the second image information are superimposed.
