Claims (7)

画像信号に応じて変調された複数のビーム光を走査させることにより画像を表示する画像表示装置であって、
前記複数のビーム光を供給する光源部と、
被照射面において、前記複数のビーム光を第１の方向と、前記第１の方向に略直交する第２の方向へ走査させる走査部と、を有し、
前記走査部は、前記第１の方向へ前記ビーム光を走査させる周波数が、前記第２の方向へ前記ビーム光を走査させる周波数より高くなるように駆動され、
前記被照射面に形成される前記ビーム光のスポットをそれぞれ前記第２の方向において点在させながら、前記複数のビーム光を順に走査させることを特徴とする画像表示装置。 An image display device that displays an image by scanning a plurality of light beams modulated according to an image signal,
A light source unit for supplying the plurality of light beams;
A scanning unit that scans the plurality of light beams in a first direction and a second direction substantially orthogonal to the first direction on an irradiated surface;
The scanning unit is driven so that a frequency at which the light beam is scanned in the first direction is higher than a frequency at which the light beam is scanned in the second direction,
An image display device, wherein the plurality of light beams are sequentially scanned while spots of the light beams formed on the irradiated surface are scattered in the second direction. 前記走査部は、前記被照射面の前記第２の方向の長さを前記ビーム光の数で等分割した長さと略一致する間隔で前記複数のビーム光を走査させることを特徴とする請求項１に記載の画像表示装置。   The scanning unit scans the plurality of light beams at an interval substantially equal to a length obtained by equally dividing the length of the irradiated surface in the second direction by the number of the light beams. 2. The image display device according to 1. 前記走査部は、前記複数のビーム光を走査させる単独の走査部を備えることを特徴とする請求項１又は２に記載の画像表示装置。   The image display apparatus according to claim 1, wherein the scanning unit includes a single scanning unit that scans the plurality of light beams. 前記走査部は、それぞれ単独又は複数の前記ビーム光を走査させる複数の走査部を備えることを特徴とする請求項１又は２に記載の画像表示装置。   The image display apparatus according to claim 1, wherein the scanning unit includes a plurality of scanning units that respectively scan one or a plurality of the light beams. 前記走査部は、それぞれ異なる入射角度で入射する前記複数のビーム光を走査させることを特徴とする請求項３又は４に記載の画像表示装置。   The image display apparatus according to claim 3, wherein the scanning unit scans the plurality of light beams incident at different incident angles. 互いに異なる色の前記複数のビーム光を合成させて前記走査部へ入射させることを特徴とする請求項１〜５のいずれか一項に記載の画像表示装置。   The image display device according to claim 1, wherein the plurality of light beams having different colors are combined and incident on the scanning unit. 同色の前記複数のビーム光を合成させて前記走査部へ入射させることを特徴とする請求項１〜６のいずれか一項に記載の画像表示装置。   The image display apparatus according to claim 1, wherein the plurality of light beams having the same color are combined and incident on the scanning unit.
