| 摘要 | An image processing apparatus projects and displays an image on a projection surface. The image processing apparatus includes an adjustment image producing section (an adjustment image producing section and an image analysis section) that produces an adjustment image for adjusting a focus of a projected image to be displayed on the projection surface and an imaging section that images the adjustment image projected on the projection surface. The adjustment image producing section changes the adjustment image to be produced, such that a grayscale pattern of a captured adjustment image obtained by imaging is close to a grayscale pattern of the adjustment image. | ||

| 主权项 | 1. An image processing apparatus for use in a projector which projects and displays an image on a projection surface, the image processing apparatus comprising: an adjustment image producing section that produces an adjustment image from adjustment image data for adjusting a focus of a projected image to be displayed on the projection surface; and an imaging section that images the adjustment image projected on the projection surface and outputs an image signal according to a captured adjustment image, wherein the adjustment image producing section changes the adjustment image data to be produced, such that a grayscale pattern of the captured adjustment image obtained by imaging is close to a grayscale pattern of the adjustment image. | ||
