Embodiment Construction

[0015] The camera needs to be driven by its embedded camera sensor chip to work, and the embedded camera sensor chips of different types of cameras are often different; in the process of research and development, production or maintenance of embedded devices with cameras, due to the needs of technology and cost, Devices of the same model often need to be replaced with different cameras. The present invention utilizes the feature that different camera sensors have different product identification numbers, and provides a dynamic identification method for camera software of embedded devices, so that the embedded device with camera does not need to be updated when the camera sensor changes due to changing the camera Instead, it dynamically identifies different camera sensors, calls and automatically loads the corresponding driver through system scanning, so that the same type of embedded device can support different cameras at the same time without updating the camera driver.

Abstract

The invention discloses a method for dynamically identifying embedded equipment camera software. The invention comprises that: a), a camera drive is initialized when the system is in start-up state; b), a camera sensor to be identified is selected and a corresponding sensor identification number is called to identify function and gain the identification number. The identification number obtained by the program is judged whether it is consistent with that of the selected sensor or not. If yes, then each driven function pointer of the identified camera sensor is valued in a corresponding field of the overall camera driven structure; otherwise, go back to Step b); c), the identified camera sensor initialization function is called. The embedded equipment camera software dynamic identification method of the invention enhances the research and development, manufacture and after-sales service efficiency of the embedded device with the camera, and lowers the product cost of each step.

Description

[technical field] [0001] The invention relates to an embedded device, in particular to a method for dynamically identifying camera software of an embedded device used for a mobile phone with a camera function, a video camera, and the like. [Background technique] [0002] The work of the camera requires a driver, and the driver is mainly for the camera sensor chip embedded in the camera. When the sensor chips in the external cameras are different, they generally need to be driven by different drivers. In the process of R&D, production, and maintenance of embedded devices with camera functions, due to technical and cost requirements, different cameras are often used for the same type of device, and the sensors embedded in these different types of cameras are often different. , which requires embedded devices such as mobile phones to update the entire built-in program. In this case, it is very inconvenient whether it is research and development, manufacture or sale; and if th...
