Movement information indicating movement of the display device is obtained, and a warning is notified when the movement information is information indicating a sickness-inducing movement set in advance as movement likely to induce motion sickness.

Display device and display device control method

Whether a similarity between a frame image and an immediately preceding frame image that is a frame image one frame before the frame image is not less than a predetermined value is determined. A corrected frame image in which the frame image is corrected in accordance with the determination result is generated. One of the frame image and the corrected frame image is displayed, according to the determination result, as a display image on a display screen.

Image display apparatus and image display method

The present disclosure changes a position of a combined image relative to a display unit in at least one of a horizontal and a vertical direction of the display unit based on information about a position and an orientation at the time of combined image display on the display unit and information about a position and an orientation of an image display apparatus at the time of image capturing by an imaging unit. In this case, the present disclosure changes the position of the combined image such that a moving amount of the combined image falls within a predetermined range in at least one of the horizontal and the vertical directions of the display unit.

Image display apparatus, image processing apparatus, image display method, image processing method, and storage medium

To provide a technique capable of reducing the transmission delay of an image, a communication apparatus wirelessly communicable with another communication apparatus, receives a compressed captured image from the other communication apparatus; decompresses the compressed captured image to obtain a decompressed captured image; generates, based on the decompressed captured image, a CG image to be superimposed and displayed on the captured image; and compresses the CG image to generate a compressed CG image; transmits the compressed CG image to the other communication apparatus. Then, the communication apparatus derives a delay time based on a transmission time of the compressed captured image in the other communication apparatus and a generation completion time of the CG image; and changes a compression ratio of the CG image based on whether the delay time is longer than a predetermined threshold.

Communication apparatus for controlling image compression and control method therefor

An information processing apparatus comprises a luminance value obtaining unit for respectively obtaining first and second luminance values of first and second captured images of a physical space, wherein the first and second captured images are respectively captured by first and second image capturing units; a parameter obtaining unit for respectively obtaining first and second tracking parameters of automatic exposure control corresponding to a change in brightness of the physical space for the first and second image capturing units; and a setting unit for setting a first image capturing parameter for the first image capturing unit based on the first luminance value and the obtained first tracking parameter and a second image capturing parameter for the second image capturing unit based on the second luminance value and the obtained second tracking parameter.

Information processing apparatus, method for controlling information processing apparatus, image processing system and non-transitory computer-readable storage medium

A display obtains a first image by image capturing, receives, from an external apparatus, a second image generated based on the first image, determines a communication quality with the external apparatus in reception of the second image, and controls to display the second image on a display unit until a value indicating a degree of degradation of the communication quality exceeds a first threshold as a result of determination, and display the first image on the display unit when the value indicating the degree of degradation of the communication quality exceeds the first threshold. The display controls to display the first image until the value indicating the degree of degradation of the communication quality becomes smaller than a second threshold smaller than the first threshold after exceeding the first threshold.

Display, control method, and storage medium

An image processing apparatus, which determines, for a combined image obtained by combining pixels of a given first image and pixels of an unknown second image either translucently or non-translucently using an unknown coefficient indicating a transparency, whether each of pixels included in the combined image is a translucently combined pixel, is provided. The image processing apparatus calculates, from pixel values of the combined image and the first image of respective pixels in a predetermined area including one pixel, pixel values of an image corresponding to the second image, calculates a total of differences between the calculated pixel values, identifies a coefficient used to obtain the combined image from the total of the difference, and determines that the one pixel is a translucently combined pixel when a value of the identified coefficient is larger than a predetermined value.

Image processing apparatus, image processing method, and storage medium

For example, display image input unitsR,L detect additional information indicating left and right directionality from images for display. Then, in a stereoscopic display device having a display device for the right eye and a display device for the left eye, a switchercapable of switching the connections between input and output input-output is controlled so that the correct image for display is provided to the correct display device. With such a configuration, even when the cables are connected incorrectly, it is still possible to input stereoscopic images to the stereoscopic display device so that such images are always displayed in the correct left-right relation.

Stereoscopic display device and control method therefor

An image processing apparatus sequentially detects a feature in an image, sequentially acquires information of the detected feature, compares information of a previous feature detected in a previous frame of the image with information of a current feature detected in a current frame of the image to sequentially determine whether to estimate that the previous feature matches the current feature, and stops the determination to record the information of the feature detected in the previous frame as information of the feature detected in the current frame in a case where the number of previous features estimated to match the current feature is equal to or greater than a predetermined number.

Image processing apparatus, image processing method thereof, and computer-readable storage medium

There is provided an image display apparatus which divides an image into plural partial images, each having a region overlapping an adjacent partial image, and displays each of the plurality of partial images on an associated one of a plurality of displays to allow a viewer to view the partial images as a single image. The image display apparatus receives an image signal corresponding to an image to be displayed, stores the received image signal in a buffer on a partial-image-by-partial-image basis, and corrects the image signal so that correction appropriate to an optical system of a display associated with each of the plurality of partial images is applied to the partial image. The speed of the correction processing is changed for each partial image represented by an image signal stored in the buffer to complete the correction of the whole image in a predetermined amount of time.

Image display apparatus and method for controlling the same

An image display apparatus has light beam emitting units (L,R) which emit light beams based on image information and a set operating frequency, and MEMS mirrors (L,R) which deflect the emitted light beams by deflection operations based on the operating frequency, in correspondence with the right and left eyes. Resonance frequency detection units (L,R) respectively detect the resonance frequencies of the MEMS mirrors (L,R). A control unit () sets the operating frequency of the MEMS mirrors (L,R) based on the detected resonance frequencies.
