Image editing apparatus

摘要

An image editing apparatus includes an input unit configured to input a moving image stream that includes a plurality of frames, an extracting unit configured to extract a specific subject from at least one of frames included in the input moving image stream, and an image processor configured to determine whether or not to perform a mask processing to the specific subject included in the at least one frame of the input moving image stream according to a predetermined output condition which is defined based on at least an output resolution of the moving image stream to be output, and performs the mask processing to the specific subject based on the determination result.

1. An image editing apparatus comprising:
an input interface configured to input a moving image stream that includes a plurality of frames; a conversion processor configured to extract a specific subject from at least one of the frames included in the input moving image stream; and an image processor configured to perform a mask processing to the specific subject for producing an output moving image stream according to whether the specific subject satisfies a predetermined output condition; wherein a display resolution of the output moving image stream is different than a display resolution of the input moving image stream; and wherein the predetermined output condition is satisfied when at least one of the following determination criteria is satisfied: Determination 1: a×V≧a2 or b×V≧b2; Determination 2: a×V≧a2 and b×V≧b2; Determination 3: a×b×V≧a2b2;
V, a, b, a2, b2 being defined as follows:V: a scale ratio of the display resolution of the output moving image to the display resolution of the input moving image;a: a width of a mask scene region of the specific subject in the input moving image;b: a height of the mask scene region of the specific subject in the input moving image;a2: a width of an output region of the specific subject in the output moving image; andb2: a height of the output region of the specific subject in the output moving image.
