Abstract:
1. A performance instruction apparatus comprising: goggle-type teaching equipment for use by a practitioner; a display section provided on the teaching equipment; an image memory for storing a guide image comprising an image representative of a hand of the practitioner playing a musical instrument and information for indicating a key to be played of a keyboard of the musical instrument and for teaching the practitioner how to manipulate his/her fingers to play keys of the keyboard; an image pickup section provided on the teaching equipment for capturing an image of at least the keyboard of the musical instrument and the hand of the practitioner playing the keyboard, so as to generate an eyesight image corresponding to an eyesight of the practitioner; and an adjusting section for reading out the guide image from the image memory and adjusting a size and a position of the read out guide image, and for displaying on the display section the eyesight image generated by the image pickup section and the adjusted guide image in a superimposed manner to indicate the key to be played and to teach the practitioner how to manipulate his/her finger to play the key; wherein, when a difference between the eyesight image and the guide image exceeds a predetermined value, the adjusting section determines that the practitioner has intentionally shifted his/her eye from the keyboard and ceases the superimposition of the guide image on the eyesight image on the display screen, and when the difference between the eyesight image and the guide image does not exceed the predetermined value, the adjusting section adjusts a resolution of the guide image in accordance with the difference between the guide image and the eyesight image and superimposes the adjusted guide image on the eyesight image.
