Claim 5:
6. The method of claim 5, wherein the at least one 3D target object comprises a first target object and a second target object, and
wherein the optimizing at least one second on-screen parameter for the at least one 3D target object based on the first on-screen parameters comprises calculating coordinates pA(uA, vA) of a face central point of the first target object and coordinates pB(uB, vB) of a face central point of the second target object so as to minimize a value expressed by the following equation:

ω1EV+ω2EH+ω3EM 

where ω1 is a weight for EV, ω2 is a weight for EH, ω3 is a weight for EM, and a sum of ω1, ω2, and ω3 is 1,
where EV is expressed by the following equation:

EV=|sA−sA′|+|sB−sB′|

where sA and sB denote height values up to tops of heads of the first and second target objects, respectively, and sA′ and sB′ denote height values up to the tops of the heads of the first and second reference objects, respectively,
where EH is expressed by the following equation:

EH=|min(hA′,hB′)−min(hA,hB)|

where hA and hB denote headroom values for the first and second target objects, respectively, and hA′ and hB′ denote the headroom values for the first and second reference objects, respectively, and
where EM is expressed by the following equation:

EM=|(uA+uB)/2−(uA′+uB′)/2|

where uA and uB denote X coordinates of the face central points of the first and second target objects, respectively, and uA′ and uB′ denote X coordinates of the face central points of the first and second reference objects, respectively.
