To provide an input device of an electronic apparatus regarding an input device of an electronic apparatus including a user interface for detecting a palm of a user by a camera, and for allowing a smooth input operation by naturally preventing the palm of the user from getting out of an area assumed through the user interface.

In an input device of an electronic apparatus, when a body part detection part detects a palm part of a user, a user interface control part sets a first moving amount of a cursor displayed in an operation screen roughly proportionally to a moving amount in longitudinal and lateral directions of the palm part of the user. When the body part detection part detects the palm part of the user near the periphery of a view angle, the user interface control part sets the first moving amount of the cursor to be larger than that when detecting the palm part near the center of the view angle.
