摘要： A selection apparatus including a display unit for indicating a plurality of displays on the same screen, a line-of-sight position detecting unit for detecting a line-of-sight position of an operator on the screen, and an input unit through which the operator inputs an instruction, the input unit operating without using a line of sight. The selection apparatus also includes a control unit. When the display unit displays all of the displays on the same screen in response to an instruction input through the input unit, and the line-of-sight position detecting unit detects the line-of-sight position on any of the displays, the control unit selects the display on which the line-of-sight position has been detected. The control unit differentiates a status of display of the selected display from those of the non-selected displays. The control unit then executes the contents of the selected display. Preferably, for example, a photographer may perform function selection by manipulating a switch while looking at a function menu displayed on the screen.
