Problems solved by technology

However, in the existing technology, although the synchronization is fast and it is not easy to lose alignment, it is necessary to ensure that the inherent difference between the master and the slaver is extremely small, otherwise there will be problems with the exposure of the slaver, resulting in abnormal output images

Embodiment Construction

[0027] As described in the Background Art, although the synchronization is fast and not easy to be out of alignment in the prior art, it is necessary to ensure that the inherent difference between the master and the slave is extremely small, otherwise the exposure of the slave will be problematic, resulting in abnormal output images.

[0028] The technical scheme of the present invention triggers the exposure and reading of pixels from the image sensor through the synchronization pulse sent by the main image sensor, and between the completion of the current frame output and the arrival of the next synchronization pulse, the invalid pixel row is output from the image sensor. On the basis of the synchronization between the image sensor and the image output from the image sensor, the normal display of effective pixels is avoided by independent exposure and reading; The exposure lines of each pixel line in the frame image are consistent, which avoids abnormal exposure of the image ...

Abstract

The invention discloses a multi-image-sensor synchronization and cooperation method and device, a storage medium and a terminal, and the multi-image-sensor synchronization method comprises the steps: receiving a synchronization pulse transmitted by a main image sensor, and enabling the synchronization pulse to indicate the initial position of a current frame; performing a read operation and an exposure operation of a pixel row in response to receiving the synchronization pulse; outputting the current frame according to the initial position of the current frame and the current frame rate; and if the next synchronization pulse sent by the main image sensor is not received after the current frame is output, outputting an invalid pixel row until the next synchronization pulse is received. According to the technical scheme, the reading quality of the image can be ensured.

Description

technical field [0001] The present invention relates to the technical field of image display, and in particular, to a method and device for synchronization and collaboration of multiple image sensors, a storage medium and a terminal. Background technique [0002] At present, in the field of mobile phone applications, the application of multi-camera technology is very common. The application of multi-cameras must first ensure the synchronization and pixel-level alignment of images output by multiple devices. In layman's terms, it is necessary to ensure that multiple image sensors obtain the same scene at the same time. However, in practical applications, the working state of the image sensor will change continuously, that is, the frame rate will change using the actual scene. Generally, when entering a dark scene, in order to obtain a longer exposure time, the image sensor will reduce the frame rate. In addition, the model of each image sensor in multi-camera applications i...
