Image capturing device and method thereof

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.

Description

technical field [0001] The present invention relates to an image capture device and method, and in particular to an image capture device and method with adjustable infrared (Infrared, IR) image signal content. Background technique [0002] In recent years, the rapid development of digital cameras has made digital cameras an indispensable necessity in daily life. Therefore, improving image quality has always been a very important issue. To put it simply, photography is to use light to reflect on objects and pass through the lens of a digital camera, and then do further image processing inside the digital camera. However, in addition to visible light, the light also includes invisible light such as infrared light (Infrared, IR) and ultraviolet light. In the prior art, optical filters are often used to filter out infrared light or to adjust the light entering the digital camera.

Problems solved by technology

If the image sensor 10 receives the infrared light signal, it is likely to be interfered by the infrared light signal when performing image processing such as color calculation and automatic white balance, resulting in a calculation error, so that the color presented by the image is different from the color seen by the human eye. big difference

However, when the light source is insufficient, the image sensor 10 usually can only increase the brightness through the flashlight, but the effect of the flashlight often makes users feel that it is not natural.
