Abstract: A condition information acquisition section of an image generation device acquires a condition of communication and condition information of a head-mounted display. An image generation section generates a display image including distorted images for a left eye and a right eye. A reduction processing section converts the display image to data in which different regions have different reduction ratios in accordance with the condition of communication, etc., and transmits the data through an output section. An image size restoration section of the head-mounted display restores the transmitted data to the display image in an original size to cause the display image to be displayed by a display section.

Abstract: An image generation device 200 processes content to draw an image (step S22), and corrects the image as needed for display (step S24). When drawing the image, the image generation device 200 adjusts a tone curve according to a user operation for adjusting the brightness expressed by pixel values (step S20). A head-mounted display 100 generates a drive voltage corresponding to the pixel values of image data acquired from the image generation device 200 (step S28) and drives a display panel to display the image (step S30). When generating the drive voltage, the head-mounted display 100 decreases the drive voltage to a ratio based on a user operation for reducing light emission brightness of the display panel (step S26).

Abstract: Disclosed herein is an image processing apparatus including: an image data acquisition section configured to acquire data of an image; a luminance conversion section configured to convert a luminance range composing a pixel value of the image so as to correspond to the luminance range capable of an output as a display image; and an output section configured to output the data of the image in which a luminance after the conversion is defined as the pixel value. The luminance conversion section acquires information regarding a linear luminance range capable of an output in the luminance that is proportional to a setting luminance in a display and determines a conversion rule at least on a basis of the information.

Abstract: An image generation apparatus increases an adjustment amount of a luminance distribution to a target value B at a time t0 at which an amount of light entering the eyes of a user changes to such a degree that the change has an influence on an action of photoreceptor cells, to thereby cause a head-mounted display to display an image 310b having a luminance increased from that of an original image 310a. The image generation apparatus gradually decreases the adjustment amount of the luminance distribution during a restoration period Δt in such a manner that an image 310c having the original luminance distribution is displayed at a later time t1.

Abstract: Provided are an image generating apparatus, an image generating method, and a program that are capable of saving the storage capacity of a frame buffer for storing pixel values of pixels determined in advance to have a predetermined value as their pixel values. An acquisition management data storing unit stores acquisition management data. A pixel value storing unit stores a pixel value of a pixel determined to have a pixel value acquired from the pixel value storing unit. An acquisition determining unit determines, based on the acquisition management data, whether or not to acquire a pixel value of each of pixels from the pixel value storing unit. A pixel value determining unit determines, with regard to the pixel determined to have the pixel value acquired from the pixel value storing unit, a pixel value acquired from the pixel value storing unit as the pixel value of the pixel. The pixel value determining unit determines, with regard to a pixel determined to have a pixel value not acquired from the pixel value storing unit, a predetermined value as the pixel value of the pixel.

Abstract: An image processing apparatus includes a calibration section acquiring luminance characteristics of a display apparatus on a basis of a user manipulation for a calibration screen image displayed on the display apparatus, a luminance transforming section transforming a range of luminance composing a pixel value of an image into a range of luminance with which the image can be outputted as a display image on a basis of the luminance characteristics, and an output section outputting data associated with an image having the luminance after the transformation as a pixel value. The calibration section adjusts an initial state of the calibration screen image on a basis of information peculiar to the display apparatus, and then causes the calibration screen image to be displayed on the display apparatus.

Abstract: A state information acquisition section of an image generation apparatus acquires state information of the head of a user. An image generation section generates a display image corresponding to a visual field. A down-sampling section down-samples image data and transmits the down-sampled image data from a transmission section. A distortion correction section of a head-mounted display performs, after an up-sampling section up samples the data, correction according to aberration of the eyepiece, for each primary color and causes the resulting data to be displayed on a display section.

Abstract: Provided is a head-mounted display 100 for displaying images transmitted from a rendering device 200. An orientation sensor 64 detects an orientation of the head-mounted display 100. An HDMI transmission/reception unit 90 receives frame data of an image to be displayed on the head-mounted display 100 and predicted orientation information of the head-mounted display 100 that is transmitted synchronously with the frame data of the image. A re-projection unit 60 corrects the frame data of the image on the basis of a difference between a latest orientation information detected by the orientation sensor 64 and the predicted orientation information so that the frame data of the image suits a latest orientation of the head-mounted display 100.
