A scheme for interactive video manipulation and display of a moving object on a background image is disclosed. In this scheme a background image stored in a background image storage unit is read out and displayed on a screen, and a manipulation target spatial position is set on the screen. Then, a partial image to be synthesized and displayed is uniquely specified from partial images which are set in correspondence to spatial positions on the background image and representing an object moving on the background image, according to the manipulation target spatial position set by the setting step, and the partial image as specified by the specifying step is read out from a partial image storage unit, and synthesized and displayed at the manipulation target spatial position on the background image. A scheme for realizing a variable speed video playback with a playback speed different from a normal one is also disclosed.

A video caption detection scheme capable of detecting captions from the coded video data which are coded by using a combination of predictive coding and motion compensation, without requiring the decoding of coded video data into frame images. In this video caption detection scheme, whether each pixel/block in the video data is coded by using inter-frame correlation without using motion compensation or not is judged. Then, a region in the video data at which pixels/blocks that is judged as being coded by using inter-frame correlation without using motion compensation are concentrated time-wise and space-wise, is detected as a caption region. The detection can be realized by counting a frequency of appearance of a pixel/block which is judged as being coded by using inter-frame correlation without using motion compensation, at each pixel/block position of a frame over a prescribed counting period, and then comparing the counted frequency of appearance with a prescribed threshold value.

A video signal, replay by a video player, is subjected to image processing by a calculation control part of a video image searching device to calculate the image quality value and another feature value. An image whose image quality satisfies a predetermined condition and whose feature value matches a predetermined condition is detected as an image in which an event has occurred. Such images are printed on an output paper together with associated addition information. A main control part of a video image access device reads out the additional information on the output paper by a scanner and effects control via a video control part to search the image corresponding to that information by a video player.

A scheme for detecting shot boundaries in the compressed video data at high speed and high accuracy. In this shot boundary detection scheme, a Predictive-picture (P picture) change is calculated from a P picture sequence in the input video data which is compressed by an inter-frame/inter-field forward direction prediction coding scheme, according to coded data contained in the P picture sequence, while an Intra-picture (I picture) change is calculated from an I picture sequence in the input video data which is compressed by an intra-frame/intra-field coding scheme, according to coded data contained in the I picture sequence. Then, a shot boundary is detected by evaluating both the P picture change and the I picture change.

A scheme for graphical user interface using a polygonal-line-shaped slider that enables a user to intuitively manipulate-and playback spatio-temporal media data such as video data and animation data without deteriorating the temporal continuity of the data in interactive manipulation and playback of the spatio-temporal media data is disclosed. In this scheme, the slider is composed of a polygonal line composed of at least one segment and a coordinate indicator that is moved along the polygonal line. Data corresponding to coordinates specified by the coordinate indicator is entered. The apparatus according to present invention stores the coordinates of vertexes of the polygonal line, stores input coordinates, maps the input coordinates onto a point on the polygonal line, and positions the coordinate indicator at the point.

Pop-up display information is created and displayed in a dynamic manner even without establishing settings in advance related to pop-up display for an anchor or an icon or the like, and implementing simple and efficient browsing by a user of linked contents by varying the display size in accordance with the display region. Mouse events of a mouse cursor upon a screen of an information device by the user are observed, and the fact that the mouse cursor has entered into a region of an object which has a linked destination is detected from the mouse events; a new window is displayed upon the screen; linked contents which are connected to the object are acquired; contents for presentation are created based upon the linked contents which have been acquired; and they are displayed within the new window which has been displayed upon the screen.

A camcorder operation condition detecting portion (103) reads image data string and detects camcorder on/off information and camcorder operating information. A video splitting portion (104) splits videos into respective shots based on the camcorder on/off information. A subject/background separating portion (105) separates a subject and a background based on the camcorder operating information, etc. A subject motion information extracting portion (106) correlates subject information separated every frame between frames. A video taken space resynthesizing portion (107) resynthesizes video taken spaces based on the camcorder operating information and the background. A shot-to-shot relation calculating portion (108) calculates spatial shot-to-shot relations between a plurality of video taken spaces. Hence, respective information of camcorder on/off, camcorder operation, subject, subject motion, resynthesized background, and shot-to-shot relation information can be spatio-temporally managed/stored, and the video taken spaces and one or more subjects can be resynthesized, displayed, or output in accordance with user's requests, etc.
