There is provided an imaging processing system and a three-dimensional (3D) model generation method capable of generating a more accurate 3D model. The imaging processing system generates the 3D model of an object by using a plurality of captured images obtained by imaging the object, and includes a plurality of polarization illumination devices that includes a polarizer and irradiates the object with polarized light obtained by transmitting light emitted from a light emitting unit through the polarizer from positions different from each other, and a plurality of polarization imaging devices that includes a polarizer and generates the captured images by using polarized light obtained by transmitting light from outside through the polarizer at positions different from each other where the object and at least one of the polarization illumination devices are within an angle of view, in which a polarization direction of the polarizer of the polarization imaging device is different from a polarization direction of the polarizer of the polarization illumination device.

Imaging processing system and 3D model generation method

There is provided a subject emphasizing device that includes a visible-light moving image acquisition unit that acquires a moving image including a subject and a background, and a subject region extraction unit that extracts a region of the subject from the moving image. Then, a background drawing unit draws background information, in a region other than the region of the subject in the moving image. An effect application unit applies a visual effect to the region of the subject, based on an intensity of the visual effect determined by an effect intensity calculation unit according to a distance from a camera to the subject. A video compositing unit combines the region of the subject to which the visual effect has been applied by the effect application unit with the background information drawn by the background drawing unit, generating a composite video.

The information processing device according to the present technology, allows a projecting unit to project a second pattern including a first pattern including repetition in first cycles in a first direction, inverted in phase in second cycles in a second direction orthogonal to the first direction, in order to acquire corresponding relationship in pixel between the projecting unit and a capturing unit. The present technology can be applied to an electronic instrument including the function of a projector or the functions of both a projector and a camera, and a computer that controls the functions.

Information processing device and information processing method

An image following a movement of a head of a user who observes an image is generated. At a drawing device, posture angle data to be received at a certain time after a time series of posture angle data that have already been received are predicted, and rendering processing is performed on an image based on the predicted posture angle data. A prediction algorithm for the posture angle data is roughly divided into two steps: (1) estimating a predicted time to receive the posture angle data; and (2) predicting the posture angle data at the predicted time. By rendering the image at the predicted time from the predicted posture angle data, a sense of delay felt when the image following the movement of the head of the user is presented is reduced.

Provided is an image signal processing apparatus including multiple color support distortion correcting units receiving a color signal of a correction target image, performing image distortion correction of a color based on a lens distortion characteristic and generating a correction image supporting the color. Each of the multiple color support distortion correcting units performs processing of receiving a reference signal indicating a pixel position in an input image applied to calculate a pixel value of an output correction image, and setting a pixel value of the pixel position indicated by the reference signal in the input image as an output pixel value.

Image processing for generating a display image based on orientation information and an angle of view

To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur.

Head mount display and display control method

Provided is a projection-type image display device including: a projection unit including a light source configured to emit light having intensity corresponding to a pixel value of an input image and a deflection unit configured to deflect emitted light from the light source using a mirror to perform scanning on a projection object; a retiming unit configured to perform retiming on pixel data of the input image in accordance with a deflection angle in the deflection unit; a shape distortion correction table having a shape distortion correction amount in each shape distortion correction table calculation position; a brightness distortion correction table having a brightness distortion correction amount in each brightness distortion correction table calculation position; and an image correction unit configured to perform distortion correction on the input image by performing signal processing based on the shape distortion correction table and the brightness distortion correction table.
