A monitoring system having a heads-up display may include a receiver, a transmitter, and a monitor device. The monitoring system may be designed to display video information in a peripheral field and may be designed to display real-time information while minimizing latency. The monitoring system may provide for the monitoring or recording of patient vital information by a healthcare professional performing medical tasks.

A display apparatus includes a display panel including a plurality of pixels and configured to display an image; a housing module including a roller therein such that the display panel is configured to be wound on the roller to be housed in the housing module or unwound from the roller to extend from the housing module; a rolling module including a structure connected to the display panel and configured to wind or unwind the display panel according to a folding or unfolding of the structure; and a vibration device on the structure, the vibration device configured to vibrate the display panel in an unwound state.

According to an aspect, an apparatus may include a media streaming device including electronic circuitry configured to receive media content wirelessly from a media content source, and an audio output cord segment having a first end portion configured to be coupled to an audio input port of the media streaming device, and a second end portion configured to be coupled to an audio rendering device, where the electronic circuitry is further configured to transmit audio content through the audio output cord segment to the audio rendering device.

Provided is a display device configured to display a video, and an information processing terminal device configured to control transmission of a video to the display device. When a video-reproducing device detects a jumping movement of a user, the video-reproducing device determines that an instruction is given to move a viewpoint position to a place on which a target mark is displayed, and transmits a request for stopping transmission to a video-providing device as a transmission source of a currently displayed video, and transmits a request for starting transmission to a video-providing device as a moving destination. When transmission of a video from the video-providing device as the moving destination is started, the movement in viewpoint is achieved, and a video captured from a new viewpoint position is allowed to be viewed on the video-reproducing device.

A control apparatus is used in a display apparatus. The control apparatus includes a laser element; a temperature sensor configured to detect a temperature of the laser element; a laser driver configured to drive the laser element; and a laser control unit configured to control a driving current to be supplied to the laser element by the laser driver, such that an optical output value of the laser element converges to a target optical output value. The laser control unit determines an initial driving current value that causes an initial optical output value to be output from the laser element, based on temperature characteristic data of the initial driving current value, and a detection temperature of the laser element detected by the temperature sensor, and controls the driving current to start from the determined initial driving current value.

An attachment device is an attachment device for attaching an electronic device body to a wall surface, and includes a base having a plurality of pin holes, a plurality of pins that are respectively inserted in the pin holes, and secure the base to the wall surface, and a locking part that is secured to the base, and on which the electronic device body is to be hung and locked. The base includes a securing surface that is a surface to be secured to the wall surface, and the pin holes are arranged outwardly from the base at a predetermined angle with respect to the securing surface.

The present application discloses a method and an apparatus for displaying an image based on privacy masking, which belong to the field of video monitoring. The method includes: acquiring a to-be-masked original image provided by an image capture terminal and privacy masking area information of the original image; wherein, the privacy masking area information is obtained by identifying the original image or is obtained from the image capture terminal and indicates an area in the original image which is required to be masked; determining whether the original image is required to be privacy-masked based on whether privacy unmasking permission information is stored; if the original image is required to be privacy-masked, performing privacy-masking on the original image based on the privacy masking area information to obtain a masked image, and displaying the masked image. In this way, the image capture terminal is only required to provide an original image without providing the original image and the masked image, so the costs of both storage and transmission are low, saving the storage resources and network resources of the image capture terminal.
