Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] Aiming at the problems of existing image sensors, the present application provides a new image sensor. In order to facilitate the understanding of this solution, the structure of the image sensor will be described first.

[0028] The image sensor includes a filter mask array (also referred to as a mask array for short) and a photosensitive element, wherein the filter mask array may also be referred to as a CFA (color filter array, color filter array). The filter mask array i...

Abstract

The application provides an image sensor. The filter mask array of the image sensor includes a transparent mask, which can improve the utilization rate of light in the image generation process, and the generated color image has a sharper boundary, so that the definition is better . This effect is more pronounced in low-light environments. In addition, the transparent mask is distributed in the middle of each colored mask, so that the colored mask is not concentratedly distributed, so that the white interpolation, that is, the white value of each pixel determined is more accurate, and the definition of the image is further improved. Correspondingly, the present application also provides a demosaicing method for demosaicing an image output by an image sensor to obtain a color image. In addition, the present application also provides an image processor to ensure the practical application and realization of the above method.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a demosaicing method, an image processor, and an image sensor. Background technique [0002] The image sensor is the component inside the camera for receiving optical signals, and it can realize the function of taking photos with the image processor. Specifically, the image sensor includes a mask array and a photosensitive element, wherein the mask array covers the photosensitive element, after the light beam passes through the mask array, the mask array filters the light beam, and the pixel array image is output after being collected by the photosensitive element. After the pixel array image is processed by the image processor, a color photo is obtained. [0003] The main function of the mask array is to filter the light beam. The masks contained in the mask array have three colors of red, green and blue. After the light beam passes through the mask...
