Abstract: Provided is a control device, an endoscope system, a processing method, and a program which can select a region other than the center region in an image to perform a predetermined process. An endoscope system includes an image generation unit which processes an image signal generated by an imaging unit to generate a display image to be displayed, a display controller which overlaps a plurality of select regions selectable according to an external operation to the display image and outputs the overlapped image to the display device, and an autofocus controller which performs a predetermined process on at least one select region selected according to the external operation.

Abstract: A control device includes a processor configured to: perform movie display control of causing a display to sequentially display images acquired in time series, and still image display control of causing the display to display any of the images as a still image; detect a first operation on a switch; determine whether a predetermined operation condition for the switch is satisfied, after the first operation has been detected; switch, when the first operation is detected while the movie display control is being executed, from the movie display control to the still image display control and causing the display to display, as a still image, an image displayed at a timing at which the first operation is detected; and cause, when the processor determines that the predetermined operation condition is satisfied, a memory to store the image displayed as a still image under the still image display control.
