Effects of Distortion Aberration Correction for
Fisheye Lenses
O Shot settings
By selecting this option, only distortion aberration correction for
correcting optical distortion is performed.
O Emphasize Linearity
This converts the image to a “central projection” style image. This
projection method is used with general lenses.
Differing from fisheye lenses, central projection displays straight lines
as straight lines. By selecting this option, a wide-view panoramic
image can be obtained. However, the periphery is stretched, resulting
in decreased resolution.
