A camera system includes a lens-changeable camera body and an interchangeable lens. The camera system includes a usage history information collecting unit configured to collect a plurality of usage history information related to a usage state of the camera system, a usage history information storage unit configured to store the collected usage history information, an information extracting unit configured to extract, from a plurality of the usage history information stored in the usage history information storage unit, usage history information related to the interchangeable lens being attached, and a lens-related information storage unit configured to store the extracted usage history information related to the interchangeable lens.

Disclosed is a method and system for playing and editing at least one video and audio file in real time. The system and method relates to a real-time video performance enhancing application, which enables a user to play one or multiple video and audio files in synchronization and during playback trigger manipulations and effects on the video and audio files using a graphical user interface.

The present invention relates to a method for the reproduction, through an audio/visual means, of a film and an apparatus for the reproduction of the same. More particularly, the method according to the present invention allows more viewings of the same film such that the film itself is automatically composed as to be different at each viewing. The method for the reproduction of a film is finalized to the creation of a multifilm, i.e. a film that changes its plot in every reproduction.

According to one embodiment of the present application, a mobile terminal displays, on a screen, an input screen for receiving additional information to be associated with an image, and receives additional information. The mobile terminal transmits the input additional information to a camcorder, according to a transfer instruction. While neither recording nor reproduction is performed, the camcorder associates the additional information from the mobile terminal, with a last recorded image when the last recorded image is not evaluated, and with a next image to be recorded when the last recorded image has been evaluated.

A verification system includes: a code generation server publicizing time stamped codes; a proving device, including a video camera, that acquires a published time stamped code from the code generation server, and, while recording a video, incorporates the acquired time stamped code into the video; and a verifying device that receives the video, extracts the time stamped code from the content of the video, compares the time stamped code to published time stamped codes, and displays a verification of the published time stamped code.

Disclosed are a method for playing a CEUS movie file, an ultrasound movie file, and ultrasound apparatus. The method comprises: receiving a playing instruction for the movie file which is a dynamic data of generated by ultrasound echoes returned from a target tissue to which ultrasound waves are transmitted by a probe of an ultrasound apparatus; determining an imaging frame rate of the ultrasound images; determining a playback frame rate of the movie file according to the imaging frame rate negatively correlated with the playback frame rate; and playing the movie file with the playback frame rate. By using the playback frame rate which is negatively correlated with the imaging frame rate to play movie files, the movie files with low frame rate can be played more smoothly and the movie files with high frame rate can be played in line with the look and feel of the human eye.

In aspects of personal content managed during extended display screen recording, a screen recording system includes a wireless device that provides digital image content for display on an extended display device, and a screen recording session on the wireless device captures the digital image content and audio data. The wireless device implements a content control module that can determine the screen recording session would capture personal content associated with a user of the wireless device. The content control module can initiate a private screen review mode in which the personal content is displayable on a display screen of the wireless device and is prevented from visual display on the extended display device. The content control module can also generate a shareable screen recording that includes the audio data and the digital image content displayed on the extended display device, without including the personal content.
