Still Picture Capture Settings
Sets the settings used when you capture still picture files. You can perform processing to make the files
suitable for use on a PC.

Reduce interlace noise
For images taken with a digital video camera, a new image is displayed every 1/30th of a second,
similar to TV images. The format used does not rewrite a whole frame (one page of the screen)
all at once, but rather rewrites a frame's image one half at a time every 1/60th of a second. On a
PC, a frame screen is captured as a single page of still pictures. Because of this, if there is rapid
movement in the image, blurring can occur between the image halves. The processing done to
compensate for this blurring and create a file without jagged edges is interlace processing. If
interlace processing is done, one page of a frame image is created by using half the image to fill
in the gaps of the other half, so the resolution deteriorates compared to images not processed this
way. It is probably not necessary to do interlace processing when capturing images with little
movement.

Lock aspect ratio
When the digital video camera uses the NTSC format, the captured still image file has a
resolution of 720 x 480 dots, which is longer vertically than the dots on a PC screen. The dots on
a PC screen form a square, so if the image is displayed as is on the PC, it will be stretched out
horizontally. This is similar to viewing a normal TV screen on a wide screen. Aspect conversion
corrects this problem. The number of horizontal dots is corrected from 720 to 640 to be able to
obtain an image with an accurate ratio. However, because the correction is done by reducing the
number of dots, the image quality deteriorates.
When the digital video camera uses the PAL format, the captured still image file has a resolution
of 720 x 576 dots, which is longer vertically than the dots on a PC screen. The dots on a PC
screen form a square, so if the image is displayed as is on the PC, it will be stretched out
vertically. Aspect conversion corrects this problem. The number of vertical dots is corrected
from 576 to 540 to be able to obtain an image with an accurate ratio. However, because the
correction is done by reducing the number of dots, the image quality deteriorates.
