CAMERA DEVICE AND METHOD FOR CAPTURING NON-BLINKING IMAGES OF PEOPLE
First Claim
1. A camera device, comprising:
- an image capturing unit, a storage system, and at least one processor; and
one or more programs stored in the storage system and executed by the at least one processor, the one or more programs comprising;
an image obtaining module operable to predefine a face feature value and an eyes feature value of people, store the face feature value and the eyes feature value into the storage system, and control the image capturing unit to capture a series of digital images of a group of persons;
a face detection module operable to detect one or more face areas from each of the digital images according to the face feature value, analyze an image resolution of each of the face areas, and count a number of faces in the face areas in each of the digital images;
an eyes detection module operable to detect an eyes area from each of the face areas according to the eyes feature value, analyze an image resolution of each of the eyes areas, and count a number of eyeballs in the eyes areas in each of the digital images; and
an image selection module operable to calculate a ratio of the number of faces and the number of eyeballs in each of the digital images, select target images whose ratio of the number of faces and the number of eyeballs is 1;
2 from the digital images, and determine one of the target images as a non-blinking image of the group of persons.

Abstract
In a method for capturing non-blinking images of people using a camera device, the camera device includes an image capturing unit and a storage system. The image capturing unit captures a series of digital images of a group of persons. A face feature value and an eyes feature value of people are predefined, and are stored in the storage system. The number of faces is detected from each of the digital images according to the face feature value, and the number of eyeballs is detected from each of the face area according to the eyes feature value. The method calculates the ratio of the number of faces and the number of eyeballs, and selects the digital image of which the ratio of the face number and the eyeball number is 1:2 as a non-blinking image of the a group of persons.
