Abstract: The present technique relates to a display device and method, and a program for presenting high-quality stereoscopic images in a simpler manner. A display unit is a four-viewpoint display device having a parallax barrier. On the display unit, block regions that are formed with pixels of channels CH0 through CH3 aligned in the parallax direction are aligned in the parallax direction. An allocation control unit allocates a parallax image for the left eye or a parallax image for the right eye to the pixels of each channel in block regions, in accordance with the viewpoint position of the user. For example, the same parallax image is allocated to pixels of two different channels adjacent to each other in the parallax direction. A generating unit generates a combined image by combining the parallax image for the right eye and the parallax image for the left eye in accordance with the allocation performed by the allocation control unit, and causes the display unit to stereoscopically display the combined image.

Abstract: Disclosed herein is a projection type image display apparatus, including: a projecting portion projecting an input image on an image projected body; a camera portion photographing the image projected body; a display control block controlling display of a projected image projected by the projecting portion; and a gesture recognizing unit recognizing a gesture manipulation of a user contained in the image photographed by the camera portion.

Abstract: There is provided a projection-type image display device including a projection section configured to project an image onto a projection body, a camera section, provided at a position different to an irradiation position of the projection section, configured to image the image projected onto the projection body, a correction amount detection section configured to remove a background from a test image imaged by the camera section at a time when a test pattern is projected onto the projection body from the projection section, detect information of coordinates related to the test pattern within the test image after background removal, and calculate correction parameters for correcting the image projected from the projection section based on the information of the coordinates, and an image correction section which corrects the image projected from the projection section based on the correction parameters.

Abstract: The present technology relates to a display device, a method, and a program for allowing a high quality stereoscopic image to be presented more easily. A display unit is a display device for four viewpoints, including a parallax barrier, and a plurality of block regions, each including pixels in channels CH0 to CH3 arranged in a parallax direction, are arranged on the display unit in the parallax direction. An assignment control unit assigns a parallax image for a left eye or for a right eye to a pixel in each channel in a block region according to the viewpoint position of a user. For example, the same parallax image is assigned to pixels in two different channels that are adjacent to each other in the parallax direction. A generation unit generates a combined image by combining parallax images for a left eye and for a right eye according to the assignment by the assignment control unit, and causes the combined image to be stereoscopically displayed on the display unit.
