Abstract: The present technology relates to an image processing device, an image processing method, an endoscope system, and a program that enable motion detection with higher accuracy. The endoscope system includes: a light source capable of performing a pulsed-light emission; a light-source control unit that controls the light source such that the light source performs the pulsed-light emission a plurality of times in an exposure time period of each captured image; an imaging unit that takes the captured images; and a motion detection unit that detects a motion of a photographic subject in the captured images. The present technology is applicable to the endoscope system.

Abstract: To more easily inhibit a change in chromaticity that occurs at the time of light amount fluctuation of semiconductor light-emitting devices without providing a feedback system. A medical light source device according to the present disclosure includes: a light source part including two or more semiconductor light-emitting devices having wavelengths of emitted light different from each other, the light source part being configured to generate light of predetermined chromaticity by mixing the light emitted from each of the semiconductor light-emitting devices and emitting outward the generated light of the chromaticity as illumination light; and a control unit configured to control a mixing rate of the light emitted from each of the semiconductor light-emitting devices in accordance with a light amount setting value of the illumination light emitted from the light source part, the control unit being configured to keep the chromaticity constant regardless of a light amount of the illumination light.

Abstract: [Object] To propose a control apparatus, a control system and a control method which are capable of appropriately determining an irradiation period in a scene in which light is radiated at the same time as imaging.[Solution] A control apparatus including: a light source control unit configured to determine a period in accordance with a period between an exposure start timing of a first line in an image pickup element and an exposure end timing of a second line in the image pickup element as an irradiation period during which a light source unit is caused to radiate light. The second line is a line in which start of exposure in one frame is earlier than in the first line.
