DEVICE AND METHOD FOR DETERMINING GESTURE AND OPERATION METHOD OF GESTURE DETERMINING DEVICE
First Claim
1. A device for determining a gesture, comprising:
- a light emitting unit configured to emit a light beam;
an image sensing device configured to capture an image of a hand reflecting the light beam; and
a processing circuit, electrically connected to the image sensing device, configured to obtain the image and determine a gesture of the hand by performing an operation on the image;
wherein the operation comprises steps of;
selecting pixels in the image having a brightness greater than or equal to a brightness threshold;
dividing the selected pixels; and
determining the gesture of the hand according to a number of group of divided pixels.

Abstract
A device for determining a gesture includes a light emitting unit, an image sensing device and a processing circuit. The light emitting unit emits a light beam. The image sensing device captures an image of a hand reflecting the light beam. The processing circuit obtains the image and determines a gesture of the hand by performing an operation on the image; wherein the operation includes: selecting pixels in the image having a brightness greater than or equal to a brightness threshold; dividing the selected pixels; and determining the gesture of the hand according to a number of group of divided pixels. A method for determining a gesture and an operation method of the aforementioned device are also provided.
