Abstract
An eye-gaze detecting apparatus is constructed as an independent adapter component, which is detachably mounted onto a camera body and which has information reflecting individual differences among observers for proper eye-gaze detection. An eye-gaze detecting adapter has an illuminating device for illuminating an eyeball of observer, an illumination drive device for driving the illumination device, an observing device for observing the eyeball of observer illuminated by the illuminating device, an observation drive device for driving the observing device, a ROM having information necessary for eye-gaze detection, a CPU for calculating an eye-gaze direction of observer with reference to the information from ROM, and a communication device for transmitting the information of eye-gaze direction obtained by the CPU to a camera body.
