Input apparatus, control apparatus, control system, electronic apparatus, and control method

Abstract

An input apparatus includes a detection section, a change section, and a transmission section. The detection section detects a movement amount of a user operation in an arbitrary direction. The change section changes a ratio of a first movement amount as a movement amount in a first operation direction corresponding to a first direction on a screen to a second movement amount as a movement amount in a second operation direction corresponding to a second direction on the screen different from the first direction, the first movement amount and the second movement amount corresponding to a detection value detected by the detection section. The transmission section transmits the first movement amount and the second movement amount whose ratio has been changed as scroll information of an image displayed on the screen.
