The present invention relates to an error correction unit for a time slice image. The present invention comprises: a stand having a length corresponding to the height of an object and standing upright; and a plurality of marker members, installed on the stand, for indicating a plurality of reference positions for setting an offset reference value, and providing the same shape in all directions. The present invention can readily set the offset reference value through the plurality of reference positions.

In an imaging system having a first camera with a first field of view (FOV) and a second camera with a second FOV smaller than the first FOV, wherein the first and second FOVs overlap over an overlap region, a method for calculating a calibrated phase detection depth map over the entire first FOV comprises calculating a stereoscopic depth map in the overlap region using image information provided by the first and second cameras, obtaining a first camera phase detection (PD) disparity map in the entire first FOV, and using the stereoscopic depth map in the overlap region to provide a calibrated 2PD depth map in the entire first FOV.

Provided is a method of spatially referencing a plurality of images captured from a plurality of different locations within an indoor space by determining the location from which the plurality of images was captured. The method may include obtaining a plurality of distance-referenced panoramas of an indoor space. The distance-referenced panoramas may each include a plurality of distance-referenced images each captured from one position in the indoor space and at a different azimuth from the other distance-referenced images, a plurality of distance measurements, and orientation indicators each indicative of the azimuth of the corresponding one of the distance-referenced images. The method may further include determining the location of each of the distance-referenced panoramas based on the plurality of distance measurements and the orientation indicators and associating in memory the determined locations with the plurality of distance-referenced images captured from the determined location.

Light-emitting or light-reflecting displays with enhanced visual and acoustic characteristics, include a display based on light-emitting elements such as light-emitting diodes (LEDs). A LED display or screen with enhanced acoustic characteristics and/or improved visual performance is herewith presented for particular use or application in a studio environment where the quality performance of both image and sound, when being captured by a camera or an audience, is challenged. The use and applications of such display, include systems and methods making use of such display, and more particularly concerning the use and application of such displays in studio environments.

A first wide angle image, a second wide angle image, a first telephoto image, and a second telephoto image are acquired from a first imaging unit 11.sub.L and a second imaging unit 11.sub.R at the same time, and particularly, optical axes of the wide angle optical system and the telephoto optical system constituting the first imaging optical system 12.sub.L match each other, and the second imaging optical system is similarly configured, and therefore, it is possible to position the main subject at a center position of the first telephoto image and the second telephoto image by independently performing pan and tilt control on the first and the second imaging unit so that the main subject is captured on the respective optical axes of the first imaging optical system and the second imaging optical system on the basis of the first wide angle image and the second wide angle image.

Provided is a detection method of a detection device. The detection device detects at least one object from an image by using depth information about the image obtained by a camera. The detection device identifies whether said at least one object is a person through three-dimensional (3D) head model matching, which matches a head candidate area of said at least one object with a 3D head model. The detection device calculates a feature for detection of a situation by using said at least one object when it is identified that said at least one object is the person.
