A processor sets one or more display parameters 600 on the basis of an eye position, and determines whether information relating to the eye position indicates a specific condition. If the information relating to the eye position is determined to indicate the specific condition, then on the basis of at least the eye position, the processor sets a display parameter 600 corresponding to a region that is closer to the boundary of an eye box 200, or a region that is farther from the center 205 of the eye box 200, than the region to which an already set display parameter 600 corresponds.

Provided are a touch input device and a program with which it is possible to suppress frequent switching of an operating mode. A touch input device 100 is provided with: an information acquiring unit 41 for acquiring state information indicating whether a touch unit 10 with which a user performs touch input is in a water-covered state or is in a normal state; and an operation control unit 42 capable of causing an operation of a device 200 to be executed in accordance with the touch input. The operation control unit 42 is capable of setting an operating mode to a normal mode when in the normal state, and sets the operating mode to an operation disabled mode when in the water-covered state. If the normal state changes to the water-covered state when the operating mode is the normal mode, the operation control unit 42 switches the operating mode from the normal mode to the operation disabled mode, and continues the operation disabled mode for a prescribed time period after switching to the operation disabled mode, even if the state returns to the normal state.
Provided is a touch input apparatus and a program that can easily achieve touch input with a plurality of detection sensitivities. A touch input apparatus 100 comprises an input detection unit 31 that detects a touch input, on the basis of a change in capacitance of a touch unit 10 through which a user enters the touch input, and a sensitivity setting unit 32 that sets a detection sensitivity for the input detection unit 31 to detect the touch input. The sensitivity setting unit 32 sets a detection sensitivity for a first region in the touch panel 10 to a first sensitivity, and sets a detection sensitivity for a second region different from the first region in the touch unit 10 to a second sensitivity which is higher than the first sensitivity. The sensitivity setting unit 32 enables coexistence of the first region and the second region in the touch unit 10.
