A control apparatus includes an acquiring unit configured to acquire a plurality of identification data indicating display performances regarding image qualities of a plurality of display apparatuses, and a generating unit configured to generate a first identification datum indicating a display performance with which all the display apparatuses are compatible using the plurality of identification data.

An image display system includes: a display device; an image supply device coupled to the display device in such a way as to be able to bidirectionally communicate and supplying an image signal; and an operation terminal having a plurality of operation buttons. The operation terminal transmits an operation signal in response to an operation on the operation button. The display device displays a first image supplied from the image supply device and a second image generated by the display device. On receiving the operation signal, the display device decides a degree of priority of the first image and the second image. The display device transmits a signal to stop updating the first image to the image supply device and executes processing based on the second image when the degree of priority of the second image is higher than the degree of priority of the first image.

A host processor includes a high-speed driver which generates first high-speed data, a coupling circuit which receives the first high-speed data from the high-speed driver, and removes a direct-current (“DC”) component of the first high-speed data to generate second high-speed data, a low-power driver which generates low-power data, and a passive switch which receives the second high-speed data from the coupling circuit, receives the low-power data from the low-power driver, and selectively outputs the second high-speed data or the low-power data to a display apparatus.

The present disclosure provides a method of controlling a high-definition multimedia interface (HDMI). The method includes: reading, by a source device, extended display identification data (EDID) of a sink device when the sink device and the source device are connected; writing information about the source device in a status and control data channel (SCDC) structure; and reading, by the source device, the EDID again based on a predetermined field value included in the SCDC structure.

A display system includes an HMD mounted on a head of a user, and a smartphone to which the HMD is coupled, and the smartphone includes a touch sensor that accepts a position input operation and detects coordinates of an operating position with reference to set coordinate axes, a magnetic sensor that detects an orientation of the touch sensor, and an adjustment unit that adjusts an orientation of the coordinate axes, based on a detection result of the magnetic sensor.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

An information processing device including a display unit, a detector, and a first control unit. The display unit capable of providing the user with a field of view of a real space. The detector detects an azimuth of the display unit around at least one axis. The first control unit includes a region limiter, a storage unit, and a display control unit. The region limiter is capable of limiting a display region of the field of view along a direction of the one axis in three-dimensional coordinates surrounding the display unit. The storage unit stores images including information relating to a predetermined target present in the field of view with the images being made corresponding to the three-dimensional coordinates. The display control unit is configured to display, based on an output of the detector, an image in the three-dimensional coordinates, which corresponds to the azimuth, in the field of view.

An image generation apparatus outputs image data to a display apparatus, performs inverse conversion on image data, and transmits the image data to the display apparatus through an external data transmission line. The display apparatus includes a display device that is capable of displaying a High Dynamic Range (HDR) image or a Standard Dynamic Range (SDR) image through the external data transmission line. The inverse conversion is performed with respect to light emission characteristics of the display device. The image data is generated by the light emission characteristic inverse conversion unit. The transmission is performed in a case where light emission characteristics of the display device approximate an Electro-Optical Transfer Function (EOTF) of the HDR, a bit precision of image data is no lower than a bit precision of the external data transmission line, and an image of the HDR is to be displayed on the display device.

An image display apparatus is disclosed. The image display apparatus includes a signal processing device having a transceiver that includes a current sweep circuit configured to output a plurality of sweep currents, a current selector connected to the current sweep circuit and configured to select a predetermined current from the plurality of sweep currents based on comparison with a reference voltage, and a comparator configured to compare a voltage output from the current selector with the reference voltage. Accordingly, a constant output voltage level can be obtained.
