Abstract: According to an embodiment, an information processing device includes a detector and a controller. The detector detects a pointed position pointed by a pointing object on a projection plane onto which light including information of an input image is projected. When the pointed position belongs to a first region on the projection plane, the controller performs control for executing first processing corresponding to an operation on the first region based on the pointed position. The first region includes a part of a projection image formed by projecting the light onto the projection plane. When the pointed position belongs to a second region on the projection plane, the controller performs control for executing second processing corresponding to an operation on the second region based on the pointed position. The second region includes a smaller part of the projection image than the part of the projection image included in the first region.

Abstract: According to one embodiment, an image processor includes a processor. The processor implements acquiring a first image and first information. The first information indicates a condition of a first projection surface. The first information includes a first color gamut of the first projection surface. The processor implements deriving a second color gamut according to the first color gamut derived by using the first information. The processor implements converting a chromaticity of the first image to obtain a second image. Each pixel of the second image has a color included in the second color gamut. The processor implements generating a first converted image by correcting the second image based on the first color gamut.

Abstract: According to an embodiment, an image processing apparatus includes a corresponding point calculator, a parameter calculator, a corrector, and a detector. The corresponding point calculator calculates corresponding points between an input image and a captured image including a projection surface onto which a projection image is projected. The projection image is generated from the input image. The parameter calculator calculates a correction parameter based on the input image, the captured image, and the corresponding points. The corrector corrects pixel values of the input image using the correction parameter with respect to each color component. The detector detects a change in the projection surface. When the detector detects the change in the projection surface, the corresponding point calculator updates the corresponding points for the change, and the parameter calculator calculates the correction parameter based on the updated corresponding points.

Abstract: According to one embodiment, a controller includes: an analyzer; a determiner; a projection image generator. The analyzer analyzes an environment of a projection surface on which an image is projected, based on a capture image obtained by capturing a region including at least part of the projection surface. The determiner determines a parameter for controlling illumination light illuminating the region based on information regarding the analyzed environment. The projection image generator generates a projection image projected on the region based on the information regarding the environment and acquired image data.

Abstract: According to one embodiment, a program listing display method includes: obtaining data of a first program and data of a second program through a communication network; obtaining, though the communication network, first reservation information of the first program and second reservation information of the second program in an electronic device; and outputting data of a program listing containing the data of the first program, the data of the second program, the first reservation information, and the second reservation information. In the data of the program listing, in accordance with newness of the first reservation information or the second reservation information, a display mode of the data of the first program differs from a display mode of the data of the second program, or a display mode of the first reservation information differs from a display mode of the second reservation information.

Abstract: According to one embodiment, an image reproducer includes: a viewpoint position acquisition module configured to acquire a viewpoint of a viewer with respect to a display surface of a display; an image data acquisition module configured to acquire image data including an image to be displayed and disposition information indicating a three-dimensional position of the image with respect to the viewer when the image is displayed to the viewer; a pixel value calculator configured to calculate a pixel value on the display surface corresponding to a pixel of the acquired image such that the acquired image is displayed at the acquired position based on the acquired viewpoint of the viewer and the acquired position; and a display controller configured to control the display to display the acquired image based on the calculated pixel value.
