摘要： An image processing apparatus includes: an amount-of-feature detection section configured to determine an amount of features of a first image and an amount of features of a second image, the first image and the second image containing the same subject; an elimination-area detection section configured to eliminate, from the second image, an area in which the amount of features extracted by the amount-of-feature detection section is larger than a predetermined threshold and to provide the second image in which the eliminated area is transparent; and an image combination section configured to superimpose the second image in which the eliminated area is transparent on the first image.

摘要： A rear projection type image display apparatus having a larger half-power angle and being capable of properly blocking a direct light from a projector for an observer is provided.The rear projection type image display apparatus includes a projector and a transmission type screen installed at an image formation plane of a projection light and made of a texture. The screen made of the texture is a diffusing material having a large half-power angle except for the direct light, and can prevent a gain from being decreased even at an angle of 60 degrees or larger. Also, a first polarizing plate is arranged in front of an exit pupil of the projector, and a second polarizing plate is arranged near a rear surface of the transmission type screen. Polarization axes of these polarizing plates are configured to be substantially orthogonal to each other, to eliminate the direct light.
