1. An operation input device that accepts non-contact operation on an operation image with a pointer, the operation input device comprising:
a display panel that displays an operation screen including the operation image on a display surface; and
a sensing portion that outputs a first output value and a second output value,
wherein
the sensing portion
outputs as the first output value a value corresponding to a distance of the pointer from the display surface in a direction perpendicular to the display surface and
outputs as the second output value a value corresponding to a position of the pointer on a plane parallel to the display surface,
if a first operation image, which is the operation image corresponding to the second output value observed when the first output value is equal to a first reference value, and a second operation image, which is the operation image corresponding to the second output value observed when the first output value is equal to a second reference value different from the first reference value, differ, the display panel displays the first and second operation images with highlighting,
the display panel newly displays the operation screen corresponding to a third operation image,
the third operation image is the operation image that is determined to have been selected and that corresponds to the second output value observed when the first output value becomes equal to a third reference value,
the third reference value is a value observed when the distance is shorter than the first and second reference values, and
when the first output value is equal to or greater than the first reference value but smaller than the second reference value, the display panel performs pointed position display to indicate the operation image being pointed with the pointer.
