You can superimpose a still image you have recorded on the “Memory Stick” on top of
the moving picture you are recording. You cannot superimpose a still image on the
tape on which you have already finished recording. You can record the
superimposed images on a tape or a “Memory Stick.” However, you can record only
superimposed still images on a “Memory Stick.”
C. CHROM (Camera Chroma key)
You can superimpose a moving picture on top of a still image such as an image which
can be used as background. Shoot the subject against a blue background. Only the blue
area of the moving picture will be swapped with a still image.
M. LUMI (Memory Luminance key)
You can swap the brighter area of a still image (such as a handwritten illustration or a
title) with a moving picture. To use this function, we recommend recording a title on
the “Memory Stick” before a trip or event.
M. CHROM (Memory Chroma key)
You can swap only the blue area of a still image such as an illustration or a frame with a
moving picture.
M. OVERLAP (Memory Overlap)
You can make a moving picture you are recording with your camcorder fade in on top
of a still image recorded on the “Memory Stick.” You can use M.OVERLAP only when
the POWER switch is set to CAMERA.
