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 invention discloses a control method, a camera assembly and a mobile terminal. The control method comprises the steps that color pixels are exposed to obtain at least one frame of color original image; within the time when the color pixels are exposed once to obtain a frame of color original image, the plurality of full-color pixels in the same subunit are exposed respectively to obtain a plurality of frames of full-color original images, the initial exposure moments of the plurality of full-color pixels in the same subunit are different, and/or the cut-off exposure moments of the plurality of full-color pixels in the same subunit are different; and correcting at least one frame of color original image by utilizing the multiple frames of full-color original images to obtain a target image. According to the invention, a plurality of panchromatic pixels with high sensitivity in the same subunit are used for staggered exposure to acquire a plurality of frames of full-color original images, the plurality of frames of full-color original images can provide correction data, and the correction data can be used for correcting at least one frame of color original image acquired by normal exposure of color pixels 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...
