The invention provides a projection type image-displaying system in which a user can readily adjust brightness and color purity of a projected image, a projection type image-displaying apparatus, and a lamp lighting-controlling method. A projector apparatus ( 10 ) recognizes an apparatus (a PC apparatus ( 30 ) or a recording/reproducing apparatus ( 40 )) connected to the projector apparatus ( 10 ), and a user or designer selects an image mode menu corresponding to an image signal input and causes the image mode menu thus selected to be displayed on a screen ( 50 ). As a result, when a projection type image-displaying system is used, the user or designer can readily and intuitively adjust brightness and color purity in order to obtain ones which he/she likes while looking at an image displayed on the screen ( 50 ).
