Abstract

The invention discloses an imaging method of an image sensor, an imaging device and an electronic device. The image sensor includes a photosensitive pixel array and an optical filter arranged on the photosensitive pixel array, the optical filter includes a filtering unit array, and each filtering unit and a plurality of adjacent photosensitive pixels in the photosensitive pixel array which are covered by the filtering unit jointly form a merged pixel. The imaging method includes the steps of: reading an output of a photosensitive pixel array, and extracting pixel values of photosensitive pixels of different merged pixels from a single frame of high-resolution image that is read to be combined, thereby obtaining multiple frames of low-resolution images; and synthesizing the multiple frames of low-resolution images. The imaging method only requires one-frame output of the image sensor to obtain a high-dynamic range image through synthesis, reduces time for waiting for data frames, and can prevent generation of ghosting.

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...
