A method of operating a switchable head-mounted display apparatus includes the steps of providing a head-mounted display that includes a switchable viewing area that is switched between a transparent viewing state and an information viewing state, switching the viewing state to an intermediate state from the transparent viewing state or the information viewing state, and switching the intermediate state to the transparent viewing state or the information viewing state.

A method for generating a stereoscopic presentation of a region-of-interest in a monoscopic information representation. The method includes the steps of: (a) selecting first and second viewpoints for the region-of-interest; (b) creating a lens surface having a predetermined lens surface shape for the region-of-interest, the lens surface having a plurality of polygonal surfaces constructed from a plurality of points sampled from the lens surface shape; (c) creating first and second transformed presentations by overlaying the representation on the lens surface and perspectively projecting the lens surface with the overlaid representation onto a plane spaced from the first and second viewpoints, respectively; and, (d) displaying the first and second transformed presentations on a display screen to generate the stereoscopic presentation.

The invention discloses a method for providing a user interface in a display device and the display device. The method for providing the user interface in the display device comprises detecting motion vectors of the display device; computing motion vectors which are used for preventing the user interface and user relative positions from changing based on detected motion vectors of the display device; moving the user interface in a display screen of the display device according to the motion vectors of the user interface. According to the method for providing the user interface in the display device, user relative position change of the display device is prevented due to the fact that the user interface on the display screen of the display device is moved and accordingly the user is prevented from dizziness and watching comfort of the user is improved.

The general field of the invention is that of peroperative optical probes designed to assist surgeons in performing medical procedures. The optical probes of the fluorescence type according to the invention are designed to be used on living tissues where the diseased areas have been marked by a fluorescent marker. They have dual lighting. The first situated in the red or near-infrared spectrum is necessary for achieving the fluorescence of the marked areas and for obtaining an image exploitable by a camera. The second situated in the visible spectrum is necessary for illuminating the marked areas with visible light, thus making the surgeon's work easier. The visible lighting can be punctiform or can be provided by an image projector. In the latter case, the projected image illuminates only the diseased areas.

The invention discloses a method and a device for automatically setting a desktop background, and electronic equipment. The method comprises the following steps of obtaining present external environment information; and selecting a matched desktop background set strategy to set up the desktop background according to the present external environment information. According to the method and the device, by obtaining the present external environment information and selecting the matched desktop background set strategy to set up the desktop background according to the present external environment information, the desktop background can be correspondingly switched according to different times, so that the use experience of users is improved, and the enjoyment is enhanced.

The invention relates to a method and system for correcting images shot in a stereoscopic mode. The method for correcting the images shot in the stereoscopic mode comprises the following steps that S1, the color deviation ratio of two camera modules used for stereoscopic shooting in a standard color temperature environment is acquired; S2, the color temperature of a used environment is measured, and the current color deviation ratio is determined; S3, two ways of images acquired by the two camera modules are corrected according to the current color deviation ratio. According to the method and system, the deviation of all ways of images on color and brightness can be adjusted dynamically in real time, the influence of the difference of an image sensor and environment light on imaging is removed, and the watching comfort level and the stereoscopic feeling can be obviously improved.

The invention discloses a control method of a media player of a vehicle and a navigation multimedia system. The control method includes acquiring a current driving condition of the vehicle, and controlling the media player according to the current driving condition. By the means, playing control of the media player is related to the current driving condition, so that better watching comfort is provided for multimedia playing in the vehicle, and playing effect is improved.

The invention belongs to the technical field of stereo display and provides a liquid crystal lens. The liquid crystal lens comprises a first substrate, a second substrate and liquid crystal molecules, wherein the first substrate and the second substrate are arranged oppositely, a plurality of first strip-shaped electrodes are arranged on the first substrate at intervals, a plurality of second strip-shaped electrodes parallel to the orientation of the first strip-shaped electrodes are arranged on the side, facing the first substrate, of the second substrate, and the two adjacent second strip-shaped electrodes are spaced by a certain distance. When the liquid crystal lens is used for 3D display, a plurality of liquid crystal lens units which are identical in structure and are distributed in an array mode are formed between the first substrate and the second substrate, each liquid crystal lens unit corresponds to one second strip-shaped electrode and at least two first strip-shaped electrodes, the width of the second strip-shaped electrodes is smaller than the distance of the liquid crystal lens units, and the central lines of the liquid crystal lens units and the central lines of the corresponding second strip-shaped electrodes are on the same straight lines. The invention further provides a stereo display device with the liquid crystal lens. Crosstalk can be obviously reduced, and the stereo display effect can be improved.

The application discloses a viewing mode switching method and device for display equipment. The method comprises the steps of: establishing at least one viewing mode in advance for the display equipment, wherein each of the viewing modes has a viewer type and a corresponding working attribute; acquiring a current viewer type; judging whether the current viewer type is matched with a certain viewer type in a pre-established viewing mode corresponding relationship, and if yes, proceeding to the next step; and switching a viewing mode of the display equipment into the viewing mode corresponding to the matched viewer type. Therefore, the viewing comfort of a viewer is improved, and related working attributes of the display equipment do not need to be manually regulated, so that use convenience and rapidness are improved.
