Abstract: The present disclosure relates to an information processing device, an information processing method, and a program capable of improving the operability in remote control of a video camera via a network. A control signal for remote control is transmitted to the video camera via a network, and an adjusted image is acquired in which an adjustment corresponding to the control signal is made on a captured image captured by the video camera.
