Abstract: A portable device and image processing method for the device are disclosed. The method includes sensing an image, performing an eye-gazing detection process on the image to detect an eye-gazing direction of at least one eye of at least one object in the image, determining whether the eye-gazing direction meets a gazing criterion, wherein the gazing criterion defines a specific angle of the eye-gazing direction of the at least one eye of the at least one object with respect to the portable device, and wherein the eye-gazing direction is determined by analyzing pupils of the at least one eye, and triggering an application of the portable device in response to the eye-gazing direction meeting the gazing criterion.

Abstract: A digital camera and an image capturing method for photographing at least one object in the digital camera. An image is sensed, and an eye-gazing detection process is accordingly preformed on the image to detect an eye-gazing direction of at least one pair of eyes of the at least one object. It is determined whether the eye-gazing direction meets a gazing criterion. If the eye-gazing direction meets the gazing criterion, an application of the digital camera is triggered.
