A system and method for computerized searching for items of interest contained in visual media assets, such as a movie or video, stores digital tag information for tagged visual media assets which includes for each tag a time code for a representative image frame, an address code for the storage location of a captured image-still of the frame, and one or more keywords representing the item(s) of interest or their characteristics. When a search request is entered with keywords for items of interest, the search result lists entries from tags containing those keywords, and can also display the captured image-stills (or thumbnail photos thereof) as a visual depiction of the search results. The search service enables advertisers and vendors to bid on rights to link their advertising and other information displays to the search results. The search service can also be used for playback of clips from media assets to viewers on a video viewing website or on a networked playback device.

The present invention relates to an image processing apparatus and a method, and in particular to an image processing apparatus and a method preferably applicable to conversion of a wide dynamic-range image having a dynamic range of pixel values wider than the normal one to a narrow dynamic-range image having a narrower dynamic range of pixel values, and to enhancement of contrast. In step S1, an input wide-DR luminance image of the current frame is converted into a narrow-DR luminance image based on the intermediate information calculated for the previous frame's wide-DR luminance image. In step S2, the stored intermediate information of the previous frame is updated using the calculated intermediate information. In step S3, it is determined if there is any succeeding frame. If there is the succeeding frame, the process returns to step S1 and processes thereafter are repeated. The present invention is applicable to a digital video camera and the like.
