A reception apparatus comprises circuitry configured to send, based on an activated mode, to an external apparatus information on gamma correction that the reception apparatus is capable of processing to display high dynamic range images on a display panel. The circuitry is further configured to receive a high dynamic range signal comprising image data in high dynamic range from the external apparatus over a transmission path, and receive information in an InfoFrame packet on gamma correction for the image data in high dynamic range. The circuitry is configured to store EDID data that includes at least information on the gamma correction for the image data.

Methods and apparatus provide for: receiving an embedded image having different information embedded in an unused area of a rectangular image format for transmitting a primary image obtained by correcting beforehand an original image in a manner canceling out the distortion thereof that appears when viewed through lenses of a head-mounted display; outputting directly to a panel of the head-mounted display the embedded image received by the receiving section; and recomposing the different information by extracting the data thereof from the unused area for the embedded image.

In an embodiment, an electronic device may be configured to capture still frames during video capture but may capture the still frames in the 43 aspect ratio and at higher resolution than the 169 aspect ratio video frames. The device may interleave high resolution, 43 frames and lower resolution 169 frames in the video sequence, and may capture the nearest higher resolution, 43 frame when the user indicates the capture of a still frame. Alternatively, the device may display 169 frames in the video sequence, and then expand to 43 frames when a shutter button is pressed. The device may capture the still frame and return to the 169 video frames responsive to a release of the shutter button.

An information processing apparatus includes an image capturing unit, a display, and a controller. The image capturing unit is configured to capture images of a real space. The display is configured to display the images. If an image of a specific portion of a target an operation of which is to be described is included in the images captured by the image capturing unit, the controller generate operation description images by adding an image for instructing the operation to the captured images and controls the display to sequentially display the generated operation description images. When generating the operation description images, the controller stores a part of the generated operation description images. If the specific portion cannot be detected from the images captured by the image capturing unit before description on the operation of the specific portion is completed, the controller displays the stored operation description images on the display.

A technology of preventing feeling of a viewer on brightness from significantly changing when content is switched is provided. A transmitting device (1) includes a calculation unit (12) that calculates a video feature of a transmission video signal, and a mute video generation unit (13) that generates a mute video posterior to a first video signal, in which luminance of the mute video is luminance corresponding to a value of a video feature relating to the first video signal.

An image generating section reads image data from an image storing section to generate an original image in keeping with the attitude of a head-mounted display. A lens distortion correcting section generates a primary image by correcting beforehand the original image in a manner canceling out the distortion thereof that appears when viewed through lenses of the head-mounted display. A different image embedding section generates an embedded image by embedding a different image into an unused area of a rectangular format for transmitting the primary image. An HDMI transmitting section transfers the embedded image to the head-mounted display.

Transmission of HDR image data is satisfactorily performed between apparatuses.

A transmission apparatus (synchronized apparatus) transmits the HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.
