Claim 14

An eye direction detecting apparatus comprising: means for defining a plurality of inside judgement zones in a finder; means for defining a plurality of outside judgement zones, each of said outside judgement zones including one of said inside judgement zones; means for detecting an eye direction to detect a gaze point of a user's eye; means for determining which of said judgement zones includes said gaze point; selecting means for judging that a user selects one of said inside judgement zones when said gaze point enters into one of said inside judgement zones; and canceling means for judging that a user cancels the selection of said judgement zone when said gaze point goes out from an outside judgement zone corresponding to said selected inside judgement zone.

Claim 15

The apparatus according to claim 10, wherein said outside judgement zones are separately positioned with respect to one another.

Claim 16

The apparatus according to claim 10, wherein said outside judgement zones are positioned in contacting relation with one another.

Claim 17

The apparatus according to claim 10, wherein said outside judgement zones are positioned so as to partially overlap with one another.

Claim 18

An eye direction detecting apparatus comprising: means for defining a plurality of focus detecting zones in a view finder, each of said focus detecting zones corresponding to respective focus detecting optical systems; means for defining a plurality of inside judgement zones, each of said inside judgement zones including a respective one of said focus detecting zones; means for defining a plurality of outside judgement zones, each of said outside judgement zones including a respective one of said inside judgement zones; means for detecting a gaze point of an user's eye; selecting means for judging that a user selects one of said focus detecting optical systems when said gaze point enters into one of said inside judgement zones; and canceling means for judging that a user cancels said selection of said focus detecting optical system when said gaze point goes out from said outside judgement zone corresponding to said selected focus detecting optical system.

Claim 19

An eye direction detecting apparatus comprising: means for defining a plurality of focus detecting zones in a view finder, each of said focus detecting zones corresponding to respective focus detecting optical systems; means for defining a plurality of inside judgement zones, each of said inside judgement zones including a respective one of said focus detecting zones; means for defining a plurality of outside judgement zones, each of said outside judgement zones including a respective one of said inside judgement zones; means for detecting a gaze point of an user's eye; selecting means for judging that a user selects one of said focus detecting optical systems when said gaze point enters into one of said inside judgement zones; and canceling means for judging that a user cancels said selection of said focus detecting optical system when said gaze point goes out from said outside judgement zone corresponding to said selected focus detecting optical system.

Claim 20

An eye direction detecting apparatus comprising: means for defining a plurality of judgement zones in a view finder; means for detecting an eye direction and judging which of said judgement zones includes a gaze point of a user's eye; and means for changing a width of said judgement zone.

Claim 21

An eye direction detecting apparatus comprising: means for defining a plurality of judgement zones in a view finder; means for detecting an eye direction and judging which of said judgement zones includes a gaze point of a user's eye; and means for changing a width of said judgement zone.
