Content data representing content that includes at least one or more components is acquired. Projection area data representing a projection area is acquired. A deteriorated part, which is a part where a projection condition is deteriorated in the projection area, is identified based on the projection area data. A priority of the component included in the content is identified. Display deterioration of the content, which is caused by the deteriorated part, is suppressed based on a position of the identified deteriorated part in the projection area, the content data displayed on the projection area, a threshold according to the identified priority, and a degree of deterioration indicative of a level of deterioration of the component.

A system and a process for accurately aligning projection mapping systems using the assistance of camera sensors. The calibration process involves first projecting a modulated gray code image sequence that allows the calibration cameras to identify a dense set of image correspondences between the calibration cameras and the projectors. The calibration cameras are then aligned to the screen surface through the selection of key points or fiducials on the screen surface that are then identified in the camera images. Once the camera(s) are aligned to the screen surface, the image correspondences between the projectors and cameras are used to determine the alignment of the projectors to the screen surface.

Projection displays include a highlight projector and a main projector. Highlights projected by the highlight projector boost luminance in highlight areas of a base image projected by the main projector. Various highlight projectors are based on steerable beams, holographic projectors, and spatial light modulators. A Fourier transform component and a mask positioned on the Fourier plane thereof are used to attenuate or eliminate selected spatial frequencies, e.g., to increase peak luminance without raising the black level of the projected image.

The present disclosure relates to an image processing apparatus and method that enable suppression of a reduction in subjective image quality. Image processing is performed on each of a plurality of frame images before projection. The image processing suppresses an influence of superimposition of the plurality of frame images in a projection image in projecting each of the plurality of frame images cyclically using a corresponding one of a plurality of projection sections. The plurality of frame images is included in a moving image. The present disclosure can be applied to, for example, an image processing apparatus, an image projection apparatus, a control apparatus, an information processing apparatus, an image projection system, an image processing method, a program, or the like.

An image processing device includes: an image acquisition unit that acquires first and second image data for projecting the image from the first and second projection units respectively; a superimposed region information acquisition unit that acquires information on a superimposed region between the projection range of the first projection unit and the projection range of the second projection unit; a first image processing unit that performs first image processing on a first portion in the first image data corresponding to the superimposed region; a second image processing unit that performs second image processing on a second portion in the second image data corresponding to the superimposed region; and an output unit that outputs the first image data after the first image processing as image data for the first projection unit and outputs the second image data after the second image processing as image data for the second projection unit.

A control method of a spectroscopic imaging device including an imaging element and a spectral element, the control method includes causing the spectroscopic imaging device to generate a first measurement spectrum consisting of N1 wavelengths by imaging a target object by making output wavelengths of a spectral element different when the spectroscopic imaging device is in a high accuracy mode and causing the spectroscopic imaging device to generate a second measurement spectrum consisting of N2 wavelengths by imaging the target object by making the output wavelengths of the spectral element different when the spectroscopic imaging device is in a high speed mode, in which N1 is an integer greater than or equal to two, and N2 is an integer less than N1.

An electronic device may have input-output devices such as sensors, displays, wireless circuitry, and other electronic components mounted within a housing. The housing may have opposing front and rear walls. A display may be formed on a front side of the device and may be overlapped by a front housing wall such as a glass layer. Sensors and other components may be formed on a rear side of the device and may be overlapped by a rear housing wall. The rear housing wall may have a glass portion or other transparent structure through which projectors project images onto nearby surfaces and through which image sensors and other optical sensors receive light. The housing may be supported by a stand. An electrical component in the stand may interact with an electronic device on the stand. Wireless circuitry in an external item may wirelessly couple to wireless circuitry within the housing.

It is desirable to provide a technology for enhancing quality of a displayed image in an overlap region among a plurality of display regions even in a case where a position of the displayed image is changed. There is provided an information processing apparatus including a display controller (134) that controls display of a displayed image in at least one display region of a plurality of display regions on the basis of an input position detected on the basis of a captured image, in which the plurality of display regions includes a first display region and a second display region, and in a case where the input position has moved to an overlap region where the first display region and the second display region overlap with each other, the display controller controls display of the displayed image in the overlap region on the basis of the input position before moving to the overlap region.
