Control device, control method, and program

Abstract

This system enables users to perform appropriate operations when switching between multiple imaging devices to control a specific imaging device for video distribution and recording. [Solution] The CPU 201 of the imaging device 110 sets a manual operation state in which at least one of the pan, tilt, and zoom of the imaging unit 210 is controlled (PTZ control) based on the user's manual operation, and also sets an automatic tracking state in which PTZ control is performed to track a subject identified from the image obtained by the imaging unit 210. When the imaging device is selected as a predetermined imaging device that performs at least one of video distribution and recording, and the state of the imaging device is set to manual operation state, if there has been no manual operation by the user for a predetermined period of time, the CPU 201 performs control to switch the state of the imaging device from manual operation state to automatic tracking state.
