A first region above the center of the guide image (Pg) shows a perspective view (D) representing the projector (1) and a supporting device (2) supporting the projector (1). A second region on the upper right of the guide image (Pg), shows six illustrations (G1-G6) affixed with numbers 1 to 6. The six illustrations (G1-G6) respectively correspond to six adjustment items related to a supporting state of the projector (1). The six illustrations (G1-G6) indicate how a projected image changes when the adjustment items are adjusted. The perspective view (D) is an explanatory diagram for clearly showing the positions of adjustment operation units that adjust the six adjustment items of the supporting device (2). In the perspective view (D), the numbers 1 to 6 are affixed near the respective adjustment operation units in balloons. ## Claims ### Claim 1 A projector supported by a supporting device including a plurality of adjustment operation units for adjusting a supporting state of the projector, the projector comprising: a projecting unit configured to project light modulated according to image information and display an image; and a guide display unit configured to display a guide image for guiding the adjustment by the plurality of adjustment operation units. ### Claim 2 (depends on 1) The projector according to claim 1, wherein the guide image includes an explanatory diagram for clearly showing the positions of the plurality of adjustment operation units. ### Claim 3 (depends on 2) The projector according to claim 2, wherein the guide image includes a plurality of illustrations indicating correspondence between the plurality of adjustment operation units and a plurality of adjustment items related to the supporting state of the projector. ### Claim 4 (depends on 3) The projector according to claim 3, wherein the illustrations represent changes of a projected image that occur when the adjustment items are adjusted. ### Claim 5 (depends on 3) The projector according to claim 3, wherein, in the guide image, signs representing order in performing the adjustment of the supporting state are affixed to both of the adjustment operation units shown in the explanatory diagram and the illustrations corresponding to the adjustment operation units. ### Claim 6 (depends on 1) The projector according to claim 1, wherein the guide image includes a test pattern for making it easy to recognize the supporting state of the projector. ### Claim 7 (depends on 1) The projector according to claim 1, further comprising: a storing unit configured to store information representing whether the guide image is automatically displayed; and a control unit configured to read out the information from the storing unit during startup and perform control based on the information. ### Claim 8 (depends on 1) An image display apparatus comprising: the projector according to claim 1; and a supporting device configured to support the projector.
