Embodiment Construction

[0031] As mentioned above, in the existing image sensor, the image sensor includes multiple rows of pixel units, the multiple rows of pixel units are divided into multiple groups, each group of pixel units includes M rows of pixel units, and each read In a period, one row of pixel units may be exposed, and another row of pixel units may be read. Wherein, the row of pixel units to be exposed may be separated from the row of pixel units to be read by a predetermined number of rows, so that the row of pixel units is read within a certain period of time after exposure to the row of pixel units.

[0032] combined reference figure 1 and figure 2 , figure 1 It is a schematic diagram of the working scene of exposure and reading of an image sensor in the prior art; figure 2 It is a timing diagram of exposure and reading of an image sensor in the prior art.

[0033] Specifically, the pixel units of the row EXP+M can be exposed first, and then the pixel units of the M row can be re...

Abstract

The invention discloses a control method and device for exposure and reading of an image sensor, a storage medium and image processing equipment. The method comprises the following steps: determiningthe line number N of pixel units read from a single group of pixel units; in the N reading periods, controlling (T + 1) * MN rows of pixel units in the current group of pixel units and the other T groups of pixel units to be exposed, controlling N rows of pixel units in the current group of pixel units to be read, wherein the exposed pixel unit rows and the read pixel unit rows are different; wherein M is larger than N, and M, N and T are all positive integers. According to the invention, the row number of the read pixel units can be effectively reduced, so that the reading efficiency is improved, and the frame rate of image output is improved.

Description

technical field [0001] The invention relates to the field of image sensor control, in particular to a method and device for controlling exposure and reading of an image sensor, a storage medium, and an image processing device. Background technique [0002] Image sensors are commonly used in a variety of electronic devices and products, such as smart phones, digital cameras, video surveillance equipment and smart devices, face recognition, drones and other products to capture and recognize images. In a typical design application, an image sensor is designed to include a pixel array composed of pixel units arranged in a row and column layout. Each pixel unit includes a photosensitive pixel for converting an optical signal containing image information into an electrical signal through the photoelectric effect, and the image signal is amplified and output to the readout circuit through the readout circuit for quantization processing. [0003] In an existing image sensor, the im...
