A display system including a display apparatus and an upgrading apparatus are provided along with a control method. A display apparatus includes an image processor which processes an image signal, a display which displays the processed image thereon, a connector to which an upgrading apparatus comprising at least one upgrading function is connected and a controller which communicates with the upgrading apparatus and controls the display to display thereon a user interface (UI) screen displaying at least one upgrading function list generated by the upgrading apparatus in response to a user selection.

Discussed herein is the adequate lighting of a target area as viewed from one or more vantage points to one or more specifications for one or more situations, and in a manner that addresses glare; in particular, glare perception. Various apparatuses, methods, and systems are presented herein whereby glare thresholds are visually indicated. Said glare-indicating apparatus, methods, and/or systems are readily implemented using existing lighting design tools, adaptable in accordance with advances in glare science, and either avoid or overcome limitations of existing glare models. Said apparatuses, methods, and systems can be adapted for real-time evaluation of glare so to, for example, aid a lighting designer in vetting generated (i.e., virtual) lighting designs and identify retrofit options for existing lighting systems.

A display apparatus that is suitable for a video wall and an operation method thereof are provided. The display apparatus includes a display panel, a memory circuit and a video processing circuit. The memory circuit is used for storing extended display identification data (EDID), and resolution information of the EDID may affect a resolution of a video frame signal of a video source. The video processing circuit transmits the video frame signal to a video output connector. Based on a video wall configuration parameter, the video processing circuit captures part or all of pixel data in the video frame signal to obtain a captured frame, and displays the captured frame on the display panel. Based on the video wall configuration parameter, the video processing circuit can adaptively change the resolution information of the EDID stored in the memory circuit.

Techniques for identifying and discriminating between different types of contacts to a multi-touch touch-screen device are described. Illustrative contact types include fingertips, thumbs, palms and cheeks. By way of example, thumb contacts may be distinguished from fingertip contacts using a patch eccentricity parameter. In addition, by non-linearly deemphasizing pixels in a touch-surface image, a reliable means of distinguishing between large objects (e.g., palms) from smaller objects (e.g., fingertips, thumbs and a stylus) is described.

Techniques for editing visual content by anchoring visual adaptation are disclosed. At least one anchor pattern is presented on a display surround. The perceptibility of the at least one anchor pattern is dependent on visual adaptation. The visual content is edited during the presentation of the at least one anchor pattern. For specific embodiments, the presentation, whether continuous or periodic, can include illumination, emission, reflection, rear projection, forward projection, or the like. A plurality of the patterns can be disposed around a reference display.

A wireless device supporting Wi-Fi Direct service includes: a display; a communication unit; and a controller configured to cause: transmitting resolution information including a plurality of resolutions that are supported by the wireless device to a second wireless device; receiving an entire image including a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions; displaying the first image by removing the second image from the received entire image when the entire image is received; and receiving the first image from the second wireless device without the second image if the resolution of the first image is included in the resolution information, the second image being an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions.

A display may have an array of display pixels to display images. Digital display data may be received by a digital-to-analog converter. The digital-to-analog converter can convert the digital display data to analog display data for the display pixels. The magnitudes of the analog display data signals that the digital-to-analog converter provides to the display pixels can be controlled by a control signal such as a reference voltage received by the digital-to-analog converter. A brightness controller may have multiple peak luminance control profiles. A brightness setting may be processed by a look-up table to produce information identifying a selected one of the peak luminance control profiles. The brightness controller may use the selected peak luminance control profile and average frame luminance for the digital display data to produce the reference voltage that controls the digital-to-analog controller.

A substantially self-contained digital instrumentation module (30) for fixed and rotary wing aircraft provides flight and other situational information, such as attitude, altitude, airspeed, and slip information, during normal aircraft operation or during emergencies, such as a failure of the aircraft's primary instrumentation. The module (30) can be mounted in any of various possible orientations. It includes redundant memories (38,40,50,52) to preserve back-up copies of software and settings during upgrades and changes. It partitions certified software from non-certified software. It can receive software upgrades and settings changes via a common portable memory device. It can automatically calculate and synchronize barometric pressure with the aircraft's primary instrumentation. It also allows for creating a customizable dimming curve (220,222), and for creating customizable range markings (114).

An image processing apparatus according to the present invention, includes: an input unit configured to receive a predetermined user operation for an image displayed on a display; a change unit configured to perform control of increasing a display range of the display in a case where the predetermined user operation is received by the input unit; a processing unit configured to perform gradation conversion on the image to improve gradation of a high brightness portion, based on the display range increased by the change unit; and a control unit configured to perform control of enabling the increase in the display range in accordance with the predetermined user operation in a case where the image satisfies a predetermined condition and disabling the increase in the display range in accordance with the predetermined user operation in a case where the image does not satisfy the predetermined condition.

An image display device a light source, an image display layer and a refractive structure layer. The light source emits a light beam. The image display layer is located over the light source. The image display layer includes plural pattern sections. The refractive structure layer has a reference plane. When the light beam is irradiated on the refractive structure layer and there is a first angle between the light beam and the reference plane, the light beam is guided to a first pattern section, so that a first image is displayed on the image display layer. When the light beam is irradiated on the refractive structure layer and there is a second angle between the light beam and the reference plane, the light beam is guided to a second pattern section, so that a second image is displayed on the image display layer.
