System and method for recording, as a single cinematic sequence of frames, images of a scene illuminated with two different lighting schemes by timing alternate actuation of the lighting schemes within pairs of adjacent frames to minimize visual motion artifacts between images captured therein

A method for recording, as a single cinematic sequence of frames, images of a scene illuminated with two different lighting schemes by timing alternate actuation of the lighting schemes within associated pairs of adjacent frames to minimize visual motion artifacts between images captured therein, the method comprising:

• establishing a first set of one or more light sources to illuminate the scene in accordance with a first one of the two different lighting schemes;
• establishing a second set of one or more light sources to illuminate the scene in accordance with a second one of the two different lighting schemes;
• capturing an image of the scene within each frame of the cinematic sequence at a predetermined base frame rate, each frame having a time duration defined by the predetermined base frame rate;
• and
• during each frame of the cinematic sequence:
• actuating during each frame of the cinematic sequence, the first and the second set of light sources in alternation on a frame-by-frame basis to capture first and second images of the scene within first and second frames of each associated pair respectively, the first and second images being illuminated by the first and second lighting schemes respectively,
• timing the alternate actuations within the associated pairs of adjacent frames relative to one another to render negligible any visual motion artifacts therebetween,
• the timing of the alternate actuations including minimizing the lighting interval duration, the lighting interval being a period of time from actuation of the first set of lighting sources to when the second lighting setup has become dark after actuation, and
• generating a timing signal to actuate the first set of lighting sources within a second half of the first frame, and to actuate the second set of lighting sources within a first half of the second frame, so that the lighting interval spans a frame boundary separating an end of the first frame from a beginning of the second frame of the associated pair, for each of the associated pairs of adjacent frames.
