PROBLEM TO BE SOLVED: To input information based on the line of sight more than restriction by resolution obtained at a line-of-sight detecting time and to make a device easy to be used. SOLUTION: This device is provided with an information kind designation means 22 making the kind of input feasible information different in every operation of plural switch means based on the line-of-sight information obtained by line-of-sight detection means 10-13 and 22 so as to make the kind of input feasible information different according to line-of-sight for every switch means which is operated. That means, the first information (range-finding area, for example) can be inputted when the first switch means 20 is operated and the second information (zoom information, for example) can be inputted when the second switch means 33 is operated in the case that the device is provided with the first and the second switch means 20 and 33, for example. |
