A projection display apparatus includes an imager that modulates light emitted from a light source and a projection unit that projects light emitted from the imager on a projection surface. The projection display apparatus includes: an imager controller that controls the imager to display a test pattern image in which a characteristic point is defined by at least three adjacent regions; an acquisition unit that acquires a captured image of the test pattern image from an imaging element configured to capture the test pattern image projected on the projection surface; and an adjustment unit that identifies the characteristic point included in the captured image on the basis of the captured image acquired by the acquisition unit and adjusts an image to be projected on the projection surface on the basis of the identified characteristic point. The at least three adjacent regions surround the characteristic point and are adjacent to the characteristic point.

Projection display apparatus

A display device includes: a display unit including a plurality of pixels each including a plurality of sub-pixels; an acquisition unit configured to acquire a numbers of sub-pixels corresponding to an amount of motion of a target image between a plurality of reference original frames; an allocating unit configured to allocate the numbers of sub-pixels acquired by the acquisition unit to an interpolated frame, in accordance with an order of the interpolated frame to be interposed between the plurality of reference original frames; and a generating unit configured to generate the interpolated frame, in accordance with the numbers of sub-pixels allocated by the allocating unit.

Display device and display method

A lighting unit includes: a light source unithaving a plurality of solid state light sources, a liquid crystal paneldisplaying an image in accordance with an image input signal, a light source controlling unitcontrolling, in accordance with the image input signal, a light amount of color component lights emitted from light source unit, and a speckle degree calculating unitcalculating a speckle degree that indicates a degree to which the color component lights generate a speckle displayed in accordance with the image input signal. The light source controlling unitchanges a control ratio between a first control mode and a second control mode, in accordance with the speckle degree acquired by the speckle degree calculating unit

Where a point corresponding to a point of interest Pis not detected and a depth value thereof is not known and where points corresponding to surrounding points Pi and Pj are detected and depth values of the points Pi and Pj are known, a depth value of the point of interest Pis determined by interpolation. A provisional corresponding point is determined from the provisional depth value. Region-based search is executed in the neighborhood of the provisional corresponding point so that precision in identifying the location of the corresponding point is improved.

Depth measuring method and depth measuring apparatus

Images of a reference object for detecting each camera position are captured by cameras and the relative position between the cameras and is obtained by using the captured images. Then, a target is placed on a turntable onto which reference marks for detecting position are formed, and while the turntable is rotated, images are captured by the cameras and . Based on the reference marks on the turntable , the positional relationship between the camera and the target is determined, and, based on the relative position of the cameras and , the positional relationship between the target and the camera is determined. A three-dimensional model of the target is produced based on the images captured by the cameras and . In this manner, a target of relatively large size is easily three-dimensionally modeled.
