The present technology relates to an information processing device, an information processing method, a program, and an information processing system for enabling reduction in a load by enabling selective arithmetic processing in performing imaging without using an imaging lens. The information processing device includes an acquisition unit configured to acquire a detection image output from an imaging element that receives incident light incident without through an imaging lens, and restoration information including setting information set by a user and to be used to generate a restoration image from the detection image, a restoration processing unit configured to perform restoration processing of generating the restoration image using the detection image and the restoration information, and an output control unit configured to control an output of the restoration image. The present technology can be applied to, for example, a device or a system that restores a detection image captured by a lensless camera.

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

A radiation imaging apparatus includes a plurality of antennas that performs at least one of reception of control data for an image capturing unit to capture radiation image data from a data processing apparatus and transmission of the radiation image data to the data processing apparatus via wireless communication, a selection unit that selects an antenna to be used from the plurality of antennas, and a control unit that controls the selection unit. The control unit restricts a selection by the selection unit such that the selection is not performed during a period when the image capturing unit captures the radiation image data.
