Color filter array, image sensor and camera module

The invention discloses a color filter array, an image sensor and a camera module. The color filter array comprises a plurality of minimum repetitive units arranged in an array; each minimum repetitive unit comprises a white filter and at least two kinds of color filters, and the at least two kinds of color filters are selected from cyan filters, purple filters and yellow filters. According to the scheme, the image exposure time in a weak light environment can be effectively reduced, so that the image noise in a night scene mode is reduced, and the image quality is improved. 本申请公开了一种色彩滤镜阵列、图像传感器以及摄像模组，该色彩滤镜阵列包括：呈阵列排布的多个最小重复单元；每个最小重复单元包括白色滤镜以及至少两种彩色滤镜，其中，上述至少两种彩色滤镜从青色滤镜、紫色滤镜以及黄色滤镜中选择。通过上述方案能够有效地减小弱光环境下的图像曝光时间，从而有利于降低夜景模式的图像噪声，提升画面质量。
