The wide-angle (or „fish-eye‟) lens fitted to SenseCam introduces distortion to the image –

lines which are straight in the real world will tend to be captured as curved lines. Clicking

on the „Undistort‟ button to the left of the „FastBack‟ button puts the Image Viewer into a

mode where it approximately corrects for this distortion. Clicking on the same button a

second time will restore the image to the original form. A side-effect of using the

undistortion option is a small black band at the top and bottom of the images.

The viewer also has to modes: Advanced Mode and Simple Mode. Advanced Mode (Error!

Reference source not found.) reveals the editing features of the viewer such as image

deletion, bookmark creation, image (un)distortion and the list of bookmarks. Simple Mode

(Error! Reference source not found.) hides all the editing features of the viewer and

simply displays the image and playback controls. Simple Mode is useful for viewing the

images without the distractions and potential dangers of accidental deletion of images. Upon

start-up, the viewer application starts in Advanced Mode. To enter Simple Mode, click the

“Simple Mode” button located in the lower left-hand corner of the viewing pane. Once in

Simple Mode, clicking the “Advanced Mode” button switches the application back to

Advanced

Mode.
