1. An input apparatus, comprising:

  • a detection unit configured to detect a movement amount of a user operation in an arbitrary three-dimensional direction;

    a processing unit configured to;

    change a ratio between a first movement amount and a second movement amount, the first movement amount in a first operation direction corresponding to a first direction on a screen, and the second movement amount in a second operation direction corresponding to a second direction on the screen, the second direction being different from the first direction, the first movement amount and the second movement amount corresponding to a detection value of the movement amount detected by the detection section;

    wherein the processing unit changes the ratio between the first movement amount and the second movement amount so that, when an angle of a judged direction of the user operation is within a first range of acceptable angles from the first operation direction, a scroll direction of the image is biased in the first direction, and changes the ratio so that, when the angle of the judged direction of the user operation is within a second range of acceptable angles from the second operation direction, the scroll direction is biased in the second direction, andwherein the first range of acceptable angles is a first angle range and the second range of acceptable angles is a second angle range; and

    determine whether to perform widening or narrowing of the first angle range and the second angle range based on the direction of the user operation,wherein the processing unit controls the first angle range and the second angle range so that the first angle range is widened when the direction of the user operation is within a first modified angle range from the first operation direction and the second angle range is widened when the direction of the user operation is within a second modified angle range from the second operation direction; and

    a transmission unit configured to transmit, based at least in part on the first movement amount and the second movement amount whose ratio has been changed, scroll information of an image displayed on the screen.
