Abstract
An eye detecting device is configured to: acquire a color image including a face of a person taken by an image taking device; generate a grayscale image by multiplying each of a red component value, a green component value, and a blue component value of each pixel of the color image by a predetermined ratio according to characteristics of a lens of glasses that the person wears; detect an eye of the person from the grayscale image; and output eye information on the eye of the person.
Claims9
An eye detecting method comprising:
- acquiring, by a processor, a color image including a face of a person taken by an image taking device;
- generating, by the processor, a grayscale image by multiplying each of a red component value, a green component value, and a blue component value of each pixel of the color image by a predetermined ratio according to characteristics of a lens of glasses that the person wears;
- detecting, by the processor, an eye of the person from the grayscale image;
- generating, by the processor, a binary image from the color image;
- extracting, by the processor, from the binary image an estimated glasses region where the glasses are estimated to be present;
- determining, by the processor, whether the person is wearing the glasses, based on a length in a horizontal direction of a white region where a plurality of white pixels continue in the estimated glasses region;
- detecting, by the processor, the eye of the person from the color image upon determining that the person is not wearing the glasses;
- and
- outputting, by the processor, eye information on the eye of the person,
- wherein the grayscale image is generated by the processor upon determining that the person is wearing the glasses.
