Problems solved by technology

However, this method needs to recompile and burn the firmware and restart the machine, which is extremely inefficient; and only one parameter can be verified at a time, which is inconvenient for comparison, so that it is impossible to choose the best effect parameter

Embodiment Construction

[0022] The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0023] The sysfs attribute function of Linux provides a user interface for operating the attributes of the device, and creates a virtual file for the user to operate, such as writing or reading the virtual file of the device driver DRIVER_ATTR to modify or read the corresponding driver. information. In fact, when operating on the driver's DRIVER_ATTR attribute file, the corresponding function, store or show, will be called: when the user writes the driver's attribute file, the driver's store function will be called, and when the user reads the driver's attribute file, the driver's show function will be called. Therefore, we can call the device-camera communication function in the store function to modify the camera parameters, so as to achieve the purpose of debug...

Abstract

The invention discloses a camera online debugging method. A camera is arranged on a mobile terminal. The camera online debugging method includes the following steps: adding DRIVER_ATTR attributes in a camera bottom driving code at an android mobile terminal, and building document nodes; connecting a person computer (PC) with the mobile terminal through a universal serial bus (USB), switching the mobile terminal to an adb mode, opening the mobile terminal camera, and observing and testing camera image effect; selecting manufacturers and models of the camera at the PC end, and filling modified parameters; calling an adb program through the PC end, writing the switched parameters in the document nodes built in the mobile terminal through the USB, executing a store function of the DRIVER_ATTR attributes through the mobile terminal, and writing the parameters in the camera; contrasting and modifying repeatedly till results are satisfied; and storing the parameters. The camera online debugging method performs online real-time humanized and efficient debugging on the camera, can effectively improve camera debugging efficiency of the android system, and picks up best effect parameters conveniently.

Description

technical field [0001] The invention relates to a camera on a mobile terminal device, in particular to an online debugging method for a camera. Background technique [0002] At present, the main method of camera debugging on mobile devices is that the manufacturer uses special tools to debug the effect on the demo board, export the parameters, and then combine these parameters into the source code of the software, and recompile the burnable Firmware and re-burn the firmware, and then turn on the camera. When running the camera application, the parameters are written into the camera through the I2C bus through the main chip of the mobile device. Under normal circumstances, the parameters debugged by camera manufacturers will be quite different from those on the demo board when the parameters adjusted by the camera manufacturer are obtained on the actual hardware platform. )Caused. In this case, some parameters must be fine-tuned. The traditional method is to modify the para...
