A projector includes a projection unit, an external I/F, an image I/F, a connection detecting unit, a manipulation detecting unit, and an instruction information generation unit. The connection detecting unit detects connection in the external I/F and the image I/F. The manipulation detecting unit causes the projection unit to project a detecting image when connection is detected and detects a manipulation performed with respect to the detecting image. The instruction information generation unit executes processing which is based on the detected manipulation.

In one aspect of the present disclosure, a digital image capturing device (DICD) is disclosed that includes a device body with a printed circuit board (PCB), and an integrated sensor-lens assembly (ISLA) that is configured for releasable connection to the device body. The PCB defines a plurality of openings that extend therethrough and includes a plurality of connector pins that are fixedly positioned within the openings. The ISLA includes at least one connective surface that is configured for contact with the connector pins to establish electrical communication between the device body and the ISLA.

An interchangeable lens that is removably attachable to a camera body includes: a first clock receiver that receives a first clock signal from the camera body; a second clock transmitter that transmits a second clock signal to the camera body; a lens that is driven by a driving force from a first drive member; a receiver that receives an instruction signal from the camera body in synchronization with the first clock signal; and a first transmitter that repeatedly transmits positional information on the lens to the camera body in synchronization with the second clock signal.

In a preferred aspect of the present invention, at least one of a camera-side controller or a terminal-side controller performs a tracking image generation process (P1) of generating tracking image data from captured image data. Further, at least one of the camera-side controller or the terminal-side controller performs a tracking calculation process (P2) of acquiring target information on the basis of the tracking image data. The tracking image data includes a high-resolution region with relatively higher resolution and a low-resolution region with relatively lower resolution. In the tracking image generation process (P1), basic tracking information including information on at least one of a size or a speed of the tracking target is acquired, and a high-resolution region and a low-resolution region are determined on the basis of the basic tracking information. The tracking image generation process (P1) and the tracking calculation process (P2) are performed in parallel.

Provided are a camera system, a camera, a lens, an accessory, and an accessory detection method of a camera system capable of simply and quickly detect presence or absence of an attachment of the accessory and a type of the accessory. Data for accessory detection is transmitted from the lens to the camera. In a case where the accessory is attached between the lens and the camera, the accessory relays the data for accessory detection. At the time of relaying the data for accessory detection, the accessory adds own accessory information to update the data for accessory detection. The camera detects the presence or absence of the attachment of the accessory and the number of attachments of the accessory based on the received data for accessory detection. Further, in a case where the attachment is detected, the camera acquires information on the attached accessory.

A wireless communication assistant tool includes an electric wire disposed at one end thereof relative to an antenna of a first wireless communication device, a camera, in a contactless condition, and at the other end thereof relative to an antenna of a second wireless communication device, a smartphone, in a contactless condition. Disposition of such electric wire permits wireless communication between the camera and the smartphone through the electric wire acting as a transmission path, so that the camera and the smartphone can make communication with each other without being interfered with other radio signals.

A communication device includes a communication unit, a communication function allocation unit, a communication status determination unit, and a communication control unit. The communication unit performs communications with another communication device using a plurality of communication paths. The communication function allocation unit allocates communication functions to each of the communication paths in the communication unit. The communication status determination unit determines a communication status for each of the communication paths. The communication control unit controls communications for each of the communication paths in accordance with allocation by the communication function allocation unit and a determination result of the communication status determination unit.

A projector includes a manipulation detecting unit that performs a manipulation detecting process on the basis of captured image data of an imaging unit, and a correction control unit that performs a distortion correcting process on the basis of the captured image data. An imaging control unit sets an image-capturing resolution of the imaging unit to resolutions different from each other between a case where the manipulation detecting unit performs the manipulation detection process and a case where the correction control unit performs the distortion correcting process.
