An electronic device (e.g., smartphone) can be connected to an external display device, allowing the electronic device to display content on the external display device. The external display device can be a standalone display device or be part of another electronic device (e.g., a laptop or tablet). The electronic device supports multiple input styles including a gesture-based input style and a non-gesture-based input style. The electronic device adapts to the external display device by using the gesture-based input style if the external display device is touch enabled and using the non-gesture-based if the external display is not touch enabled. Additionally or alternatively, the external display device adapts to the input style being used by the electronic device by displaying an augmentation bar associated with the content and supporting the non-gesture-based input style when the external display device detects that the electronic device is using the gesture-based input style.

Technologies are disclosed herein for controlling a head-mountable heads-up display system comprising a heads-up display unit and a hand cover. The hand cover includes a plurality of input elements located on appendages thereof that are configured to cause the hand cover to transmit input signals to the heads-up display unit. The heads-up display unit is configured to display virtual image content within a field of view of a user. As a result of receiving a user input, the heads-up display unit may display virtual image content based on a user input. The heads-up display unit updates the virtual image content as a result of receiving an input signal corresponding to an interaction between a pair of input elements of the hand cover. The heads-up display system may be useable in connection with a system of an outdoor recreational area to obtain information regarding the outdoor recreational area.

A light emitting substrate, a method of driving a light emitting substrate, and a display device are provided. The light emitting substrate includes a plurality of light emitting units arranged in an array. Each light emitting unit includes a driving circuit, a plurality of light emitting elements, and a driving voltage terminal. The plurality of light emitting elements are sequentially connected in series and connected between the driving voltage terminal and the output terminal of the driving circuit.

A computing device includes a display device, an accelerometer, and an orientation determination module. The orientation determination module sends a heartbeat of orientation data obtained by the accelerometer to a host device at a first data transfer frequency, and compares a plurality of orientation data most recently received from the accelerometer for at least one axis of orientation to the current orientation data measurement. In response to a difference between the current measurement and any of the plurality of orientation data most recently received from the accelerometer exceeding a threshold, the computing device sends the current orientation data to the host device at a second data transfer frequency, and adjust content displayed on the display device based on the current orientation data received by the host device.

Active control of LEDs, LED packages, and related LED displays by way of pulse wide modulation (PWM) is disclosed. Effective PWM frequencies for LEDs are increased by segmenting duty cycles in which LEDs are electrically activated within individual PWM periods. Segmented duty cycles may be provided by transforming or re-ordering a sequence in which control signals are provided to LEDs. As such, LEDs may be electrically activated and deactivated multiple times within each PWM period. Active electrical elements that are incorporated into one or more LED packages of an LED display may be capable of segmenting the duty cycle within each LED package. Active electrical elements may also be capable of receiving reset signals from a data stream to either initiate a reset action or pass the reset signals along to other active electrical elements of a display.

It is an object to realize a correcting process for correcting a defective image in a region of interest (ROI) that is a partial region segmented from a captured image. A transmitting apparatus includes a controlling section that controls the holding of defect correcting information for use in correcting a defect in an image included in a ROI and a transmitting section that sends out image data of the image included in the ROI as payload data and sends out ROI information as embedded data.

An apparatus, method, and computer readable medium that access a frame buffer of a graphics processing unit (GPU), analyze, in the frame buffer, a frame representing displayed data, based on the analyzed frame, identify a reference patch that includes an instruction to retrieve content, generate an overlay including an augmentation layer which includes the content, superimpose the overlay onto the displayed data such that the content is viewable while a portion of the base layer is obscured, detect a user input, determine a location of the user input in the augmentation layer, associate the location in the augmentation layer with a target location in the base layer, and associate, within memory, the target location with an operation such that the user input in the augmentation layer activates an input in the base layer.

A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.
