Abstract

The invention discloses an imaging method. Firstly, an image sensor is provided. The image sensor includes an array of photosensitive pixels and a filter arranged on the array of photosensitive pixels. The filter includes an array of filter units, and the filter unit includes a white filter area. and color filters. The white filter area and the color filter area respectively cover a plurality of photosensitive pixels. Next, reading the output of the photosensitive pixel array to combine the outputs of the photosensitive pixels covered by the color filter area of ​​the same combined pixel into a color analog signal, and combining the outputs of the photosensitive pixels covered by the white filter area into a grayscale analog signal, Then process the color analog signal and the grayscale analog signal to obtain the pixel values ​​of the merged pixels to generate a merged image. The resulting merged image contains complete color information, high brightness and clarity, and less noise. The invention also discloses an imaging device which can be used to realize the imaging method and an electronic device using the imaging device.

Description

technical field [0001] The invention relates to imaging technology, in particular to an imaging method, an imaging device and an electronic device. Background technique [0002] The arrangement of the filter pixels of the existing image sensor is RG, GB or RW, GW, wherein R, G, B and W represent red, green, blue and white respectively. RG, GB is the traditional arrangement, 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 way in which the output of the existing photosensitive pixels is combined is relatively noisy, and the signal-to-noise ratio is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide an imaging method, an imaging device and an electronic d...
