Embodiment one
Fig. 2 is refer to, embodiments of the invention one are:A kind of camera adjustment method, it is adaptable to the end of Android system End equipment, comprises the following steps:
S1:Image effect parameter in the register address of the register of camera sensing device and the register is carried out Association, obtains incidence relation;The value of value comprising register address and image effect parameter in the incidence relation.
S2:The incidence relation is saved in default configuration file;
S3:Detect the image effect of camera;For example, can directly open camera application checks image effect.
S4:Judge whether image effect is not good, if so, then performing step S5.
S5:The image effect parameter in incidence relation in first terminal modification configuration file;Can be on first terminal Change the value of the image effect parameter in configuration file;The first terminal can be computer, such as PC, tablet personal computer.
S6:Amended configuration file is sent to the second terminal where camera by first terminal;The second terminal For the android terminal equipment with camera.Further, configuration file can be sent out by modes such as copy, file transmission It is sent to second terminal;Preferably, it is transmitted by adb communications.
S7:Second terminal obtains camera sensing device ID;Further, the host CPU of second terminal is read by I2C and imaged Head sensor ID, i.e., obtain camera sensing device ID from the ID registers of camera sensing device.
S8:Judge whether the camera sensing device ID is correct, if so, step S9 is then performed, if it is not, then performing step S10;Wherein, correct camera sensing device ID is obtained in the specification that can be provided from sensor producer, if second terminal is from ID The camera sensing device ID obtained in register is consistent with the camera sensing device ID in specification, then the camera sensing device ID is correct.
S9:Incidence relation of the second terminal in the configuration file, image effect parameter setting to camera is passed In sensor in corresponding register;Perform step S3.Further, second terminal reads the incidence relation in the configuration file Get in buffer (buffer), then the register address in incidence relation, the image effect in incidence relation is joined Number is set into camera sensing device in corresponding register.
S10:Judge camera module exception or be not present.
Wherein, step S101 and S102 are performed on first terminal, and register address and image effect parameter can be direct The initialization sequence parameter given according to camera sensing device producer compiles the parameter of corresponding format.
Camera module includes I2C interfaces and MIPI interfaces (or parallel port) with main hardware communication modes between host CPU, I2C paths are mainly used to carry out the reading or setting of camera sensing device configuration register, mainly realize that function such as CPU passes through I2C obtains the ID of camera sensing device, and by I2C by image effect parameter setting into camera sensing device, camera Sensor is received after correct register configuration parameter, and camera module just can normal work and output image.And image is defeated Go out and be exactly transferred to by MIPI interfaces in host CPU, host CPU is again by the processing to picture format, and this sampled images can just be exported Onto the LCD (liquid crystal display) of android terminal equipment.
The present embodiment is by the way that the handling process of original reading effect configuration parameter was changed to from matching somebody with somebody in file system Put file to go to obtain image effect parameter, without going to directly read parameter from kernel mirror images, configured with realizing that dynamic changes File can just verify the purpose of new parameter effect at once;Directly save recompility kernel, programming kernel and restart start and consumed The time taken, and changing configuration file and being sent to time of android terminal equipment can almost ignore compared to the above time Disregard, so as to reach the purpose of fast verification camera image effect, greatly improve the efficiency of camera image effect optimization. Meanwhile, the initialization sequence parameter direct editing that the present embodiment directly can be given according to camera sensing device producer is into corresponding format Parameter, or carry out disposable batch importing, all debugging and volume according to the one or more image effect parameters to be changed Collecting work can be completed at PC ends, and debugging effect can be checked by disposably importeding into android terminal equipment finally by adb orders Really, simplify debugging step to greatly improve debugging efficiency with this.
Embodiment two
The present embodiment is a concrete application scene of above-described embodiment.
In the driving code of kernel (kernel) camera sensing device, open after camera success, reading every time In the code flow of sensors register configuration parameter sequence, the register configuration parameter sequence in kernel mirror images is not directly read Row, and the image effect parameter configuration files under some path for the equipment that is changed to open a terminal, such as/etc/gc0310.ini; The register address and its corresponding efficacy parameter that write on configuration file in advance are read in internal memory buffer (buffer), and And set the value of the image effect parameter in buffer into corresponding camera sensing device register, so that without compiling again Code and programming kernel mirror image are translated, the image effect of new parameter can be just checked at once.Need to change again when image effect is not good During new parameter, the modification of some image effect parameters need to be only carried out to configuration file on PC, then passes through the communication modes such as adb By configuration file push to andorid device ends, camera is finally reopened using can just check new effects parameter at once Image effect, it is such as dissatisfied to be iteratively repeated above-mentioned steps until debugging out optimized image effect location, can thus reach Carry out the purpose of camera effect fast debugging.
Compared with former Android system scheme, by directly saving recompility kernel, programming kernel and restarting start institute The time of consuming, the efficiency of debugging camera image effect will be greatly improved.
