Abstract

The present Invention provides image generating technology capable of expressing a complex yet natural movement of the characters with less image data regardless of the playback speed. A image generating device of the present invention comprises a parameter generating circuit (201) which generates the playback speed parameter regarding the original image structured from a plurality of frame images, a time base interpolation circuit (202) which specifies frame images existing just before and behind the timing on the time base displayed by the playback speed parameter, and interpolates a new posture specifying information regarding frame images which should be existing in a timing on the time base utilizing posture specifying information to specify each posture of the moving objects, and a weighting interpolation circuit (203) which refers to interpolated posture specifying information regarding each of the two types of moving images displaying movement modes of differing moving objects, generates new posture specifying information by weighting interpolation between the two types of moving images, and obtains a moving image which displays a new movement mode (for example, M0A regarding “walking” and M0B regarding “running”).

Dependent claims

An image generating device for generating a new moving image from moving images of moving objects recorded in a time series for changing postures of said moving objects inside a virtual space, each of said moving objects comprising two different types of moving images, wherein said image generating device displays an intermediate posture of the respective moving object depicted in said two types of moving images by performing:

a primary interpolation, which corresponds to time base adjustment, for assigning to respective frames parameters indicated in ratios of positions on a time base with a primary frame as a reference point and, based on such assigned parameters, generating frame images corresponding to the positions on the time base indicated by a designated playback speed parameter in a number of frames corresponding to said playback speed parameter;
and
a secondary interpolation, which corresponds to a space position adjustment and is implemented when the primary interpolation generates different frame images displaying a movement mode of a same moving object equivalent to a same position on the time base, for interpolating mutual posture specifying information preset to the respective moving objects with designated interpolation parameters regarding the frame images.
