Base Claim:
1. A camera system comprising: a) an image sensor; b) an electronic display operable as a viewfinder and configured to display a current scene being viewed by the image sensor; c) a memory; d) a wink detecting subsystem comprising a light emitter configured to emit light toward a camera user's eye, and a light detector configured to: (i) sense reflected light from the eye; and (ii) output electronic data corresponding to the reflected light from the eye; e) a controller coupled to the image sensor, electronic display, subsystem, and memory, and being configured to: (i) process image data generated by the image sensor to display a current scene viewed by the image sensor on the electronic display; (ii) receive, from the subsystem: (1) first electronic data indicating that the user is gazing at the electronic display based on the reflected light from the user's eye; (2) second electronic data indicating that the user's eye has closed based on an interruption in the reflected light from the user's eye; and (3) third electronic data indicating that the user's eye has opened based on the reflected light from the user's eye; (iii) determine when the user's eye has winked based at least in part on the first, second and third electronic data by measuring the length of time between the second electronic data and the third electronic data and determining that the user's eye closed for a threshold amount of time to distinguish the wink from a blink; and (iv) in response to determining that the user's eye has winked, initiate a first camera function; f) a touchpad fitted with a solid overlay, the solid overlay having at least two cutouts on its surface, such that (1) the at least two cutouts provide defined areas for touch sensing on the touch pad and (2) each defined area for touch sensing corresponds to a defined camera function for the camera controller.

Claim 2:
2. The system of claim 1 , wherein the first camera function is to take a picture and one of the defined camera functions for the camera controller is to take a picture.
