Abstract

The present invention provides a method and device for rapidly displaying the initial frame image and rapidly capturing an image, by setting an image processing unit, which is connected with the application processing unit through the first data line and the first control line, and connected with the image acquisition unit through the first The second data line is connected with the second control line. In addition to controlling the image acquisition unit, the image acquisition unit can also perform certain preprocessing on the image, thereby effectively reducing the burden on the AP. Compared with the architecture in which the AP is connected to the camera, the present invention effectively improves the mismatch between transmitted images and control commands caused by hardware initialization, long image acquisition time, and mismatch between captured images and command-issued time stamps. Issues affecting user experience.

Description

technical field [0001] The invention relates to the field of image acquisition and processing, in particular to a method and device for rapidly displaying an initial frame image and rapidly capturing an image. Background technique [0002] At present, when the camera collects image data, the initiation of the collection command, the setting of the collection parameters, and the subsequent processing of the collected images are all done through the AP (application process), and the AP and the camera are directly connected through the data line and the control line. , one-way control, serial operation. Taking the display of the initial frame as an example, the AP first needs to initialize the camera, then obtain the window size to display the image, configure the output image size, and then initialize the ISP (image signal process) of the AP itself. It is necessary to wait for the ISP initialization to complete. , in order to normally receive the data output by the camera. S...
