Embodiment Construction

[0046] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present application, and should not be construed as limiting the embodiments of the present application.

[0047] see figure 2 , Figure 4 and Figure 17 , the present application is a control method for the image sensor 10 . The image sensor 10 includes a plurality of panchromatic pixels and a plurality of color pixels arranged in a two-dimensional pixel array, and the color pixels have a narrower spectral response than the panchromatic pixels. The two-dimensional pixel array includes a plurality of minimum repeating units, and each minimum repeating unit includes a plurality of panchromati...

Abstract

The application discloses a control method, a camera assembly and a mobile terminal. The control method includes: exposing the color pixels to obtain at least one frame of color original image; during the time when the color pixels are exposed once to obtain a frame of color original image, a plurality of panchromatic pixels in the same subunit are respectively exposed to obtain multiple frames of panchromatic In the original image, multiple panchromatic pixels in the same subunit have different starting exposure moments, and / or multiple panchromatic pixels in the same subunit have different cutoff exposure moments; use multiple frames of panchromatic original images to correct at least one frame Colorize the original image to obtain the target image. This application utilizes the staggered exposure of multiple high-sensitivity panchromatic pixels in the same subunit to obtain multiple frames of panchromatic original images, and multiple frames of panchromatic original images can provide correction data, which can be used to correct the normal exposure of color pixels At least one frame of the color original image is obtained, so as to eliminate motion blur of the color original image.

Description

technical field [0001] The present application relates to the field of image technology, and in particular to a control method, a camera assembly and a mobile terminal. Background technique [0002] Motion blur (Motion blur) is the dislocation between scenes caused by the relative displacement between the imaging system and the shooting object, especially in application scenarios such as long exposure time or fast moving speed of the shooting object, the problem of motion blur is particularly prominent. The most commonly used technical means to eliminate motion blur is to sample and store the motion information of the subject during the acquisition of a frame of image, and use it as an information source for back-end data processing to restore image information using different algorithms. Existing solutions for eliminating motion blur require the use of relatively complex hardware systems, and the back-end processing requires calibration and compensation, resulting in high a...
