Image conversion process and apparatus

A process for producing a second frame sequence for giving a visual impression of an event including a temporal dimension to an observer, the process comprising:

• producing a second frame sequence, including a second frame change rate and a second frame interval, from a first frame sequence having a first frame change rate and a first frame interval, wherein all of the frames of the second frame sequence are obtained by additively superimposing at least two temporally neighboring frames of the first frame sequence, wherein an intensity amount of each of the at least two neighboring frames for producing a frame of the second frame sequence is determined based on a frame-specific, individually evaluated intensity weighing coefficient, such that the two neighboring frames of the first frame sequence combine together to correspond to a time of the frame in the second frame sequence;
• wherein the time of the frame in the second frame sequence is represented by a time location of a characteristic point in time of the second frame interval during which the frame appears in a transmission or reproduction in a transmission or reproduction standard being assigned to the second frame sequence;
• and
• wherein a common starting point and time for the first frame sequence and the second frame sequence to be produced is determined,
• a location in time of each frame of the first frame sequence and a location in time of each frame of the second frame sequence is determined,
• for each frame of the second frame sequence to be produced, the temporally next neighboring frames of the first frame sequence are determined,
• a temporal distance or offset of respective time intervals of the next neighboring frames of the first frame sequence with respect to a time interval of the frame of the second frame sequence to be produced is determined, based on their respective characteristic points,
• for each of the next neighboring frames of the first frame sequence, a frame specific, normalized intensity weighing coefficient is determined which depends on the temporal distance or offset, respectively, of the corresponding time interval with respect to the time interval of the frame of the second frame sequence to be produced, and
• the frame of the second frame sequence to be produced is formed by additively superimposing the next neighboring frames of the first frame sequence, each being multiplied by its corresponding intensity weighing coefficient.
