Further, described promising result is user's visual effect, then is promising result when reaching user's Expected Results.Effect herein is user's naked-eye observation without unified standard.
Further, described modification camera parameter is that part is revised, and part is revised as fine setting.
Further, described portable terminal comprises mobile phone, computer, camera.
Revise the DRIVER_ATTR attribute that drives one of webcam driver code file the inside definition, as: static DRIVER_ATTR (camera_debug, 0664, para_show, para_store); Then the driver_create_file function by Linux imports the camera_debug attribute into to create property file in the probe of driver function.The para_show function can be used for checking the purposes such as correctness of parameter, wouldn't relate to.The supplemental characteristic of the set form that will import in the para_store function converts digital array to, and then the communication program of invocation facility and camera is with the parameter read-in camera;
Parameter read-in can come into force, thereby changes the effect of camera, can observe new effect by revising relevant parameter at once when dissatisfied to current effect, and can return last parameter, and contrast draws best effect repeatedly.Final argument is derived disposable being incorporated in the firmware at the PC end.
This method is not to need specially the PC end that the linux system is housed, windows, and linux, Mac OS etc. can be used by the PC end that android adb supports; PC end does not need to read the parameter of current camera, oneself reads the parameter read-in camera that originally had because mobile phone is understood when entering camera, and the parameter that just will need to regulate that this method needs writes by the PC end; This method is not saved in the final argument that obtains in the portable terminal, but is kept at the PC end;
Camera manufacturer can give an effect debug much the same parameter to us, the parameter that we give camera manufacturer is according to being incorporated into the code the inside by the form that portable terminal cpu writes camera, then we understand firmware of compiled code generation, be burnt to the portable terminal the inside, open camera by calling camera application program behind the mobile terminal-opening, mobile phone cpu will be with parameter read-in to camera in this process.If see that effect is dissatisfied, just need debugging: traditional amending method just have to remodify the relevant parameter of code the inside for us, and then recompilates firmware of generation, be burnt in the portable terminal, start is checking again, again and again.Compiling, burning, starts etc. all are processes consuming time.
And amending method of the present invention only need to be connected to computer with portable terminal by the USB line, directly revising on computers corresponding parameter just can make the parameter on the portable terminal change, thereby can immediately see the effect behind the parameter change, immediately revise parameter after dissatisfied, until find out suitable parameter.
The present invention has done following improvement:
A.PC is with the connection of computer.This method uses the adb of android to connect, and PC can access the file system of portable terminal by adb, just can pass to portable terminal to parameter by the file in the file system of writing portable terminal.
The parameter that the b.PC end is revised need to be written at last camera and just can come into force.This method realizes the DRIVER_ATTR attribute among the linux in portable terminal bottom program, in the portable terminal Virtual File System, will create corresponding property file like this, and the RIVER_ATTR attribute of this method has comprised the operation that the parameter that will import file system into is write into camera in realizing, that is to say that PC writes property file the inside in the mobile terminal document system to parameter by adb, mobile terminal system will be write parameter in the camera and go.
C. need to defer to certain standard from PC to the parameter of portable terminal and just can be written to camera, and the form of the camera write parameters of different vendor is also different.This method, becomes to meet the form that writes the camera standard in the format conversion of PC end with input by selecting manufacturer's model at the PC end, writes in the portable terminal by adb again.
D. debugging is to afterwards parameter preservation of promising result problem.Because the effect of this method is that the camera effect is finely tuned, so the last parameter that only needs to revise a part gets final product, if need to relate to the problem of replacing original parameter in the portable terminal so result parameter is saved in, difficulty is larger in the realization, so do not plan to be saved in portable terminal, this method adopts can be by being saved in last parameter in the PC file at the PC end, the parameter craft of preserving is incorporated in the code to get final product like this, this large increase efficient.
E. different vendor's parameter read-in method form may be different.Need to before revising a certain parameter, to write certain sign to camera first such as some camera, also to write certain sign so that parameter comes into force after writing parameter, this method is selected manufacturer's model at the PC end by option is set, automatically to convert the form that meets to.
Above content is in conjunction with concrete optimal way further description made for the present invention, should not assert that implementation of the present invention is confined to above explanation.For those skilled in the art, without departing from the inventive concept of the premise, can also make some simple deduction or replace, within the protection domain that the claim that all should be considered as being submitted to by the present invention is determined.
