Claim 7
Independent Claim
122 words
A device for directing a camera operation by detecting operator's eye-gaze direction, said device comprising: eye-gaze direction detection means for detecting a direction of an eye-gaze of an operator who is looking into a finder, in a predetermined eye-gaze operation area of said finder and for outputting an eye-gaze operation signal; manual operation means for outputting a manual operation signal by a manual operation; mode selection means for making a selection between an eye-gaze operation mode which uses the eye-gaze operation signal and a manual operation mode which uses the manual operation signal; and photographic operation direction means for directing photographic operation, including at least starting of a photo-taking operation, in accordance with the operation signal selected by said mode selection means.
Claim 8
Dependent Claim
54 words
A device for directing a camera operation by detecting operator's eye-gase direction according to claim 5, further comprising a mode selection control means for switching over said mode selection means from the manual operation mode to the eye-gaze operation mode when a shutter speed is set to a value lower than a predetermined value.
Claim 9
Dependent Claim
91 words
A device for directing a camera operation by detecting operator's eye-gaze direction according to claim 5, further comprising an exposure control means for controlling exposure in accordance with a first program diagram when the manual operation mode is selected by said mode selection means for controlling exposure in accordance with a second program diagram when the eye-gaze operation mode is selected by said mode selection means, a shutter speed determined by said second program diagram being slower than that determined by said first program diagram relative to the same exposure value.
