Abstract: Provided is an imaging control device including: a processor; and a memory connected to or built in the processor. The processor acquires a first image by causing an image sensor of an imaging apparatus to image first light with a first sensitivity, and acquires a second image by causing the image sensor to image second light with a second sensitivity. The first sensitivity is a sensitivity for representing shape information of a subject with a first gradation in the first image. The second sensitivity is a sensitivity for representing temperature information of the subject with a second gradation in the second image.

Abstract: The zoom lens includes, in order from the object side, a first lens group that has a positive refractive power, a second lens group that has a negative refractive power, a third lens group that has a positive refractive power, a fourth lens group that has a positive refractive power and has a stop disposed to be closest to the object side. During zooming, the second lens group and the third lens group move, and the other lens groups remain stationary. The first lens group consists of, in order from the object side, two groups of cemented lenses in which a negative meniscus lens and a positive lens are cemented, and a cemented lens in which a positive lens and a negative lens are cemented. During focusing, only the cemented lens closest to the image side in the first lens group moves.
