Image capturing device and method thereof
First Claim
1. An image capturing device, comprising:
- an image sensor, configured to obtain a target image, wherein the image sensor comprises;
a color filter array, comprising a first region permitting visible light and infrared light to pass and a second region permitting the infrared light to pass; and
a sensor chip, obtaining the target image by the color filter array, wherein the target image comprises;
a composite image corresponding to the first region;
a first group infrared image corresponding to the second region, wherein the composite image is composed of a RGB image and the second group infrared image; and
a processor, generating a processed image by employing the first group infrared image,wherein under a normal mode, the processor retrieves the RGB image from the composite image by employing the first group infrared image and sets the retrieved RGB image as the processed image, andwherein under a glimmer mode, the processor adjusts the weight of the second group infrared image in the composite image by employing the first group infrared image to generate the processed image.

Abstract
An image capturing device and a method thereof are provided. The image capturing device includes an image sensor and a processor. The image sensor includes a color filter array and a sensor chip. The color filter array includes a first region permitting visible light and infrared light to pass and a second region permitting the infrared light to pass. The sensor chip obtains a target image through the color filter array, wherein the target image includes a composite image corresponding to the first region and a first group infrared image corresponding to the second region, and the composite image includes a second group infrared image, where the second group infrared image and the first group infrared image are linear correlated. The processor adjusts a proportion of the second group infrared image in the composite image by employing the first group infrared image, so as to generate a processed image.

8. An image capturing method, applicable to an image capturing device, the image capturing method comprising:
-
obtaining a target image by the image capturing device, wherein the step of obtaining the target image comprises; receiving light by a color filter array, so that visible light and infrared light pass through a first region of the color filter array and the infrared light passes through a second region of the color filter array; and generating a composite image corresponding to the first region and a first group infrared image corresponding to the second region by a sensor chip, wherein the composite image is composed of a RGB image and the second group infrared image; and generating a processed image by employing the first group infrared image, wherein under a normal mode, the processor retrieves the RGB image from the composite image by employing the first group infrared image and sets the retrieved RGB image as the processed image, and wherein under a glimmer mode, the processor adjusts the weight of the second group infrared image in the composite image by employing the first group infrared image to generate the processed image. - View Dependent Claims (9, 10, 11, 12, 13)
