Information processing terminal, information processing device, and system

An information processing device comprising:

• circuitry configured to
• select at least one captured image among a plurality of captured obtained by an imaging unit, and
• transmit, to a device, a control signal that instructs execution of one or more corresponding pre-registered functions based on the at least one captured image selected from the plurality of captured images obtained by imaging an object in contact with or in proximity to the imaging unit,
• wherein the imaging unit is controlled to obtain the plurality of captured images, each captured image having a different distance between a lens and an imaging element of the imaging unit according to movement of the lens, and
• wherein the imaging unit is controlled to start obtaining the plurality of captured images when the movement of the lens is detected.

A system comprising:

• an information processing terminal;
• and
• an information processing device,
• wherein the information processing terminal includes:
• an imaging unit configured to image an object in contact with or in proximity to a translucent member via the translucent member;
• and
• circuitry configured to
• control imaging by the imaging unit;
• and
• transmit information, based on at least one captured image among a plurality of captured images obtained by the imaging unit, to the information processing device,
• wherein the imaging unit includes an imaging element and a lens provided such that a distance from the imaging element varies according to movement of a movable member to which the translucent member and the lens are fixed,
• wherein the circuitry performs control to obtain the plurality of captured images, each captured image having a different distance between the lens and the imaging element,
• wherein the circuitry performs the control to start obtaining the plurality of captured images when the movement of the movable member is detected, and
• wherein the information processing device includes:
• circuitry configured to
• select at least one captured image among the plurality of captured obtained by the imaging unit
• transmit, to a device, a control signal that instructs execution of one or more corresponding pre-registered functions based on the at least one captured image selected from the plurality of captured images captured by the imaging unit.
