A video display two way mirror assembly for taking self pictures without holding a device includes a personal electronic device that has an electronic display to display imagery for a user. A housing is vertically oriented on a support surface to facilitate a user to stand in front of the housing. A camera is integrated into the housing to capture imagery of the user. A two way mirror is integrated into the housing to facilitate the user to view a reflection of themselves in the two way mirror, and a display is positioned behind the two way mirror. The display displays indicia comprising imagery to facilitate the user to view the image captured by the camera superimposed onto the reflection of themselves.

This disclosure describes a portable recording device that is configured to capture real-time multimedia data from a surrounding environment. The portable recording device may comprise one or more sensors to capture the real-time multimedia data, a category selector to selectively toggle between preset positions that designate a category classification to the real-time data, and an activation button to trigger one or more actions relating to the capture of the real-time multimedia data.

A stereo microscope includes a stand, two optical image acquisition units configured to connect to the stand to capture a stereoscopic image, which define an imaging plane using two optical axes of the image acquisition units, a pair of video glasses including two optical image reproduction units, each having an optical axis and a display for reproducing an image, which together define an image plane, wherein the optical image reproduction units are arranged to produce a stereoscopic image impression, and two optical axes of the optical image reproduction units define an image reproduction plane, a detection device configured to determine spatial orientation of the video glasses, the image reproduction plane, the image plane and the imaging plane, and a control unit configured to pivot the stand so that the intersection lines of the image plane and the imaging plane on the image reproduction plane are made parallel. Methods are also disclosed.

A video signal transmission and reception system includes a video signal receiver in a video signal reception module, a video signal transmitter in a camera module, and a specific video signal transmitter in a specific camera module. In the specific camera module, a frame signal generated by a frame signal generator is sent to the video signal receiver from the specific video signal transmitter. The frame signal is sent to the video signal transmitters in a plurality of the camera modules from the video signal receiver.

An excellent display can be performed even when the frame rate changes dynamically at the reception side. When a switching portion at which a sequence of video streams to be transmitted is switched from a first sequence to a second sequence having a different frame rate from the first sequence is provided, display control information is inserted into at least encoded image data of a picture corresponding to the switching portion or a packet containing the encoded image data. A reception side performs display control of pictures using the display control information and implements an excellent display.

A management device includes a distance sensor, a sensor interface, and a processor. The distance sensor is configured to measure a distance between a predetermined position and a backmost side of a commodity line having commodities biased in an arrangement direction and supported from a foremost side of the commodity line. The sensor interface transmits and receives data to and from the distance sensor. The processor calculates a length of the commodity line based on the distance before a change in the distance and the distance after the change in the distance when the distance is changed, and determines whether the length of the commodity line matches a thickness of the commodity indicated by shelf label information. The processor calculates the increased or decreased number of commodities based on the determination.
