INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, PROGRAM, AND MOBILE BODY

The present technology relates to an information processing apparatus, an information processing method, a program, and a mobile body that make it easy to acquire information regarding a convoy of mobile bodies such as vehicles. The information processing apparatus is disposed in a first mobile body, and includes a convoy information detection section, a convoy information generation section, and an output control section. The convoy information detection section detects, based on a first optical signal outputted from a second mobile body preceding the first mobile body, convoy information regarding a convoy of mobile bodies including up to the second mobile body. The convoy information generation section updates the convoy information by adding information regarding the first mobile body to the convoy information. The output control section controls an output section in such a manner as to output a second optical signal to rearward of the first mobile body in accordance with the updated convoy information. The present technology is applicable, for example, to a vehicle designed for autonomous driving.
