Digital camera and image capturing method
View Patent ↗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.
1. An image processing method for a portable device capable of photography, comprising:
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.
2. The image processing method as claimed in claim 1 , further comprising, asserting an indication signal if the gazing criterion is not met thereby allowing the at least one object to react for meeting the gazing criterion.
3. The image processing method as claimed in claim 1 , wherein the indication signal is a voice signal, a blinking LED or a displayed character.
4. The image processing method as claimed in claim 1 , further comprising configuring the gazing criterion prior to performing the eye-gazing detection process.
5. The image processing method as claimed in claim 1 , wherein the gazing criterion defines a number of the at least one of eyes gazing at the portable device.
6. The image processing method as claimed in claim 1 , wherein the eye-gazing detection process is performed when a trigger button of the portable device is pressed.
7. The image processing method as claimed in claim 1 , wherein:
the eye-gazing detection process further comprises detecting at least one face in the image; and
locating the at least one eye within the detected faces.
8. The image processing method as claimed in claim 1 , wherein the portable device captures the image, stores the image, records the image as a moving picture, or asserts an indication signal indicating that the gazing criterion is met as the triggered application of the portable device in response to the eye-gazing direction meeting the gazing criterion.
9. A portable device capable of photography, comprising:
a photo sensor module, operative to sense an image;
a user interface, comprising:
a display, operative to display the image;
a memory device, for storage of the image;
a processor, coupled to the photo sensor module, memory device, and user interface, 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, determining whether the eye-gazing direction meets a gazing criterion, and triggering an application of the portable device in response to the eye-gazing direction meeting a gazing criterion,
wherein the gazing criterion defines a specific angle of the eye-gazing direction of the pair of eyes 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 pair of eyes.
10. The portable device as claimed in claim 9 , wherein the user interface asserts an indication signal if the gazing criterion is not met, thereby allowing the at least one object to react for meeting the gazing criterion.
11. The portable device as claimed in claim 9 , wherein the indication signal is a voice signal, a blinking LED or a displayed character.
12. The portable device as claimed in claim 9 , wherein the gazing criterion is configured through the user interface.
13. The portable device as claimed in claim 9 , wherein the gazing criterion defines a number of at least one eye gazing at the portable device.
14. The portable device as claimed in claim 9 , wherein the processor performs the eye-gazing detection process to further:
detect at least one face in the image; and
locate the at least one eye within the detected at least one face.
15. The portable device as claimed in claim 9 , wherein the processor triggers the portable device to capture the image, store the image into the memory device, record the image as a moving picture, or assert an indication signal through the user interface for indicating that the gazing criterion is met if the eye-gazing direction meets the gazing criterion.
