Abstract

The invention discloses an imaging method, comprising the steps of firstly, providing an image sensor, wherein the image sensor comprises a photosensitive pixel array and a filter arranged on the photosensitive pixel array, the filter comprises a filter unit array, each filter unit comprises a white filter area and a color filter area, the white filter area covers a photosensitive pixel, and the color filter area covers at least one photosensitive pixel; and then, reading the outputs of the photosensitive pixel array to output analog signals generated by the photosensitive pixels covered by the color filter areas of the same combined pixels, combining the analog signals into color analog signals, and obtaining pixel values of the combined pixels according to the color analog signals and gray-scale analog signals corresponding to the white filter areas to generate a combined image. The obtained combined image includes complete color information, and is high in brightness and definition and low in noise. The invention further discloses an imaging device for implementing 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...
