Abstract

The invention discloses an imaging method comprising steps of: providing an image sensor including a light-sensing pixel array and a light filter disposed thereon, wherein the light filter comprises a light filtering unit array and each light filtering unit comprises a white light filtering region and a color light filtering region each of which covers multiple light-sensing pixels; reading an output of the light-sensing pixel array in order to combine the outputs of the light-sensing pixels covered by the color light filtering region of a combined pixel into a color analog signal and to combine the outputs of the white light filtering region into a gray analog signal; processing the color analog signal and the gray analog signal to obtain a pixel value of the combined pixel to generate a combined image. The combined image involves complete color information and has high brightness and sharpness and few noise points. The invention also discloses an imaging device capable of implementing the imaging method and an electronic device using the imaging device.

Description

Technical field [0001] The present invention relates to imaging technology, in particular to an imaging method, imaging device and electronic device. Background technique [0002] The arrangement of filter pixels of existing image sensors is RG, GB or RW, GW, where R, G, B, and W represent red, green, blue, and white, respectively. RG, GB are the traditional arrangement methods, which can collect accurate color information, but there are many noises and unclear under low illumination. RW, GW arrangement can receive better definition under low illumination, but the color will be inaccurate. In addition, the existing method of combining the output of the photosensitive pixels has relatively high noise and low signal-to-noise ratio. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention needs to provide an imaging method, imaging device and electronic device. [0004] ...
