An input apparatus, in particular, of a type for enabling an input operation in a contactless manner, smoothly, as is intended by a user, comprises a distance detector means for detection a distance from that input apparatus to a user's hand, a distance change detector means for detecting change of distance upon basis of a result of detection by the distance detector unit, and an instruction output means for providing an instruction to an apparatus of an outside, upon basis of a result of detection by the distance change detector means, wherein the distance change detector means detects that the distance is changed, starting from a predetermined first distance, as a beginning of the change of distance, reaching to a second distance, and the instruction output means treats the result of detection by the distance change detector means as an operation made by the user, and thereby providing the instruction to the apparatus of an outside. |
