Our original algorithm uses three pixel-interpolation filters to convert the CCD's 4.0 effective megapixels to the recorded equivalent of about 8 megapixels. As well as being able to print out a detailed image very clearly, even on A3-size paper, you can also enlarge part of an image without sacrificing image fidelity.
In wide angle mode, you can get as close as 2 cm from your subject and still capture it in stunningly clear detail. Thanks to the super macro function, close-ups are now easier than ever.
This mode gives priority to a picture's composition, and prevents off-center shots where the subject is out of focus, by automatically conducting distance measurements for a center area and five points within it at the top, bottom, left, right and center.
The Xacti J4's high-intensity white LED provides the extra luminance you need when taking close-ups in low light conditions. It also assists in calibrating the auto focus range in low light conditions, when distances are normally difficult to measure.
