Abstract

The invention discloses an automatic detection method and system for a camera module, wherein the configuration parameters of the types of all camera modules supported by a chip software driver are preset in the chip software driver. The method comprises the steps of sending an operation request to a to-be-configured camera module, and judging whether a response exists or not; If the to-be-configured camera module responds to the operation request, obtaining an ID register value of the to-be-configured camera module; comparing the ID register value with the ID value of any camera module supported by the chip; and if the ID register value is consistent with the ID value of the camera module supported by the chip, calling a camera module configuration parameter of the ID register value supported by the chip, and carrying out configuration adjustment on the to-be-configured camera module. According to the method and the device, the type of the camera module accessed to the camera input system can be automatically identified, more camera modules are supported, and meanwhile, the preset configuration parameters are called for configuration, so that the error rate is reduced, and the working production efficiency is improved.

Description

technical field

[0001] The present application relates to the technical field of camera control, in particular to a camera module automatic detection method and system. Background technique

[0002] Camera, also known as computer camera, computer eye and electronic eye, is a video input device, which is widely used in video conferencing, telemedicine and real-time monitoring. In order to expand the imaging range of images and improve user experience, dual-camera technology is widely used in mobile phones, driving recorders, monitoring and other fields.

[0003] At present, in the development of dual-camera software and hardware, it is carried out for the situation where the camera module model is known, but in the software and hardware development of the chip design manufacturer, it is hoped to support as many camera module models as possible, and increase the number of chip-to-camera module models. selectivity. So that different developers may use different camera modules...
