Abstract

The invention provides a colour filter array and an image sensor. The colour filter array comprises multiple colour filter units; each colour filter unit is composed of total four rectangular pixels including a first pixel, a second pixel, a third pixel and a fourth pixel; the long side of each rectangular pixel is two times of the short side; the first pixel and the second pixel are sequentially appressed and arranged in a short side alignment manner along the first direction, where the long side is; the third pixel and the fourth pixel are sequentially appressed and arranged in a short side alignment manner along the first direction; and the first pixel and the third pixel are sequentially staggered, appressed and arranged by taking the length of the short side as the staggering distance along the second direction, where the short side is. By means of the colour filter array and the image sensor provided by the invention, on the premise that the resolution ratio of the image sensor is not reduced, the area of the unit colour filter pixel is increased to the most extent; and thus, the sensitivity of the image sensor is improved.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of image sensors, and in particular relate to a color filter array and an image sensor. Background technique [0002] With the continuous development of image sensor technology, people have higher and higher requirements for the resolution of the image sensor. Therefore, it is necessary to integrate more color filter pixels per unit area of ​​the image sensor to improve its resolution. At the same time, in view of the cost requirements and the continuous reduction in the size of various smart terminals such as mobile phones, tablet computers, and digital cameras used in image sensors, it is necessary to continuously reduce the area of ​​the color filter pixels integrated on the image sensor to meet the requirements of reducing the size of the image sensor. volume and the requirement to increase its resolution. [0003] However, the smaller the area of ​​the color filter pixels integrat...
