Problems solved by technology

[0003] However, the multi-frame synthesis technology adopted by mobile phones in the related art has the problem of long waiting time for multi-frame data due to the need to obtain multi-frame data
In addition, if there are objects moving in the frame when shooting multiple frames of data, it is easy to produce ghost images after compositing

Abstract

The invention discloses an imaging method of image sensor, an imaging device and an electronic device. The image sensor comprises a photosensitive pixel array and an optical filter (comprising an optical filter unit array); every optical filter unit and multiple photosensitive pixels covered by the optical filter unit form one combined pixel; the image sensor also comprises a lens array; every micro lens is arranged corresponding to one photosensitive pixel; the sizes of at least two micro lenses in the multiple micro lenses corresponding to the multiple photosensitive pixels in a combined pixel are different. The imaging method comprises: reading the output of the photosensitive pixel array, extracting and combining the pixel values of the photosensitive pixels of different combined pixel from the read single frame of high resolution image so as to obtain multiple frames of low resolution images; and synthesizing the multiple frames of low resolution images. According to the imaging method, only one frame of the image sensor is output, the images of high dynamic range can be obtained through a synthesizing mode, therefore, the time waiting for data frames is reduced, and ghosting is avoided.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an imaging method of an image sensor, an imaging device and an electronic device. Background technique [0002] At present, the diversification of mobile phone camera functions has won the favor of the majority of users. Many mobile phones use multi-frame synthesis technology when taking pictures, that is, let the image sensor of the mobile phone continuously output several images, and then synthesize them by software to achieve different shooting Effects (such as HDR, night scene effects, etc.) to enrich the user experience. [0003] However, the multi-frame synthesis technology adopted by the mobile phone in the related art has the problem of long waiting time for multi-frame data due to the need to acquire multi-frame data. In addition, if there are objects moving in the frame when shooting multiple frames of data, it is easy to produce ghost images after compositing. Cont...
