There is provided an information processing device, an information processing method, and a program that enable information presentation with high usability. On the basis of presentation location information regarding a change in state of a presentation location where presentation information is presented and at least one piece of information out of processing information regarding processing for generating the presentation information, user information regarding a response of a user to the processing, and environment information regarding a state of an environment of the presentation location, control of at least one state of a presentation state of the presentation information and a state of the processing is performed. The present technology can be applied as a projection device for the inside of a vehicle, a conference room, or the like.

The projector includes an exterior chassis provided with a housing section, a light source unit which is housed in the exterior chassis, and is configured to emit light, an image forming unit which is housed in the exterior chassis, and is configured to generate image light from the light, a projection optical unit which is attached to the exterior chassis, and is configured to project the image light, and an imaging unit which is configured to image the image light projected, and is detachably attached, wherein the imaging unit is housed in the housing section.

It is possible to optimize a mode of a screen for watching content. An image processing apparatus (10) according to the present disclosure includes: a shape determination unit (152) that determines a screen shape suitable for displaying content on the basis of an automated driving state of a vehicle and information regarding the content to be displayed on a screen provided in the vehicle; and an image creation unit (153) that creates an image of the content to be displayed on the screen according to the shape determined to be suitable for displaying the content by the shape determination unit (152).

There is provided a see-through display and a method for operating a see-through display. The display is configurable to display additional image content for augmenting a user's view of a scene visible through the display. According to the method, image data are received defining an image of a scene visible through the display. By analysis of the received image data, one or more characteristics of the scene are determined. A light effect to be applied to the user's view of the scene is determined. Additional image content is generated according to the determined light effect and according to the one or more determined characteristics of the scene. The generated additional image content is displayed to the user such that light received from the scene is combined with the additional image content, thereby to implement the determined light effect in the user's view of the scene.

A projection system and a projection method are provided. The projection system includes a digital micromirror device, a digital light processing chip, and a display processing chip. The display processing chip receives a first image signal with a variable frame rate from an external signal source, and outputs a second image signal with one of a plurality of fixed projection frame rates to the digital light processing chip according to the first image signal and one of the fixed projection frame rates supported by the projection system. The digital light processing chip drives the digital micromirror device according to the second image signal. The projection system and the projection method of the invention may realize a variable frame rate function and effectively improve smoothness of a projection image.

A projection system controlling method includes identifying a first correspondence, identifying a second correspondence, identifying a third correspondence between a plurality of pixels corresponding to an overlap region in an image projected by a first projector, accuracy of the third correspondence is higher than accuracy of the first correspondence, identifying a fourth correspondence between a plurality of pixels corresponding to the overlap region in an image projected by a second projector, accuracy of the fourth correspondence is higher than accuracy of the second correspondence, projecting an image onto a region different from the overlap region based on the first correspondence, projecting an image onto the overlap region based on the third correspondence, projecting an image onto a region different from the overlap region based on the second correspondence, and projecting an image onto the overlap region based on the fourth correspondence.

A projection control device that controls a projection portion which projects an image to a projection surface includes a ray position detection portion that detects an irradiation position of a ray irradiated on the projection surface, and a specific image superimposition control portion that superimposes a predetermined specific image on a region corresponding to the irradiation position in the image. In a state where the specific image is superimposed on a first region corresponding to a first position detected by the ray position detection portion in the image, the specific image superimposition control portion, in a case where the irradiation position moves out of a predetermined range including the first position, moves the specific image to a region corresponding to the irradiation position that has moved, and in a case where the irradiation position moves within the range, continues superimposition of the specific image on the first region.

The present disclosure relates to the technical field of digital projection display, and discloses a projection method and a projection apparatus. The method includes: acquiring a target object image; identifying attribute information of a target object based on the target object image; acquiring preset projection content based on the attribute information of the target object; acquiring a projection path; and projecting a projection screen based on the preset projection content and controlling the projection screen to move along the projection path. In this way, the projection is more flexible and more pertinent.
