Description

Method and system for switching PDAF (PDAF) in real time

Technical Field

The invention relates to the field of high-pixel cameras, in particular to a method and a system for switching PDAF (digital video camera function) in real time.

Background

The english name of focusing is Focus, and generally, digital cameras have a plurality of focusing methods, namely, an automatic focusing method, a manual focusing method and a multiple focusing method. For example, 1, auto focus: that is, a non-TTL camera is usually used to implement auto-focusing by a similar visual distance measurement method, and the camera emits an infrared ray (or other rays) to determine the distance to the object according to the reflection of the object, and then adjusts the lens assembly according to the measured result to implement auto-focusing. The automatic focusing mode is direct, fast, easy to implement and low in cost, but sometimes errors occur (the automatic focusing cannot be achieved when other things such as glass exist between a camera and a shot object or under the condition of insufficient light), the precision is poor, and the mode is not generally used by high-grade cameras nowadays. 2. Manual focusing: manual focusing is a focusing method that adjusts a camera lens by manually rotating a focusing ring so as to make a shot picture clear, and the method greatly depends on the discrimination of human eyes on an image on a focusing screen and the proficiency of a photographer or even the eyesight of the photographer. 3. Multiple focusing: many digital cameras have a multi-point focusing function, or an area focusing function. When the focus center is not set at the center of the picture, multi-point focusing, or multi-focusing may be used. 4. Holographic automatic focusing: the holographic automatic focusing function (Hologram AF) is a unique function of a Sony digital camera and is also a brand-new automatic focusing optical system, an advanced laser holographic photographing technology is adopted, the edge of a photographing main body is detected by using laser points, a picture which is accurately focused can be photographed even in a dark environment, and the effective photographing distance reaches 4.5 meters.

With the wider application of high-pixel cameras in mobile phones, the quality of image quality is improved, and the continuous development of camera focusing technology and the increasing requirements of clients on the focusing speed and effect of cameras (cameras) are met, and the initial manual focusing is developed into the current automatic focusing. In the auto-focusing process, devices such as electronic cameras generally use a contrast method or a phase method (i.e., PDAF, phase focus type focusing system) to perform focusing. Contrast detection autofocus is continually adjusted before the maximum contrast is detected, and thus is slow. As more and more items of PDAF are also used, the conventional focusing method is still reserved for the purpose of compatibility with the focusing effect in the dark. The PDAF is also called Phase Detection Auto Focus (Phase Detection Auto Focus), and literally means "Phase Detection Auto Focus". Since the focusing is completed only by one calculation, the focusing speed is extremely high. But the focus tends to be out of alignment in dark places. As early as phase focusing (PDAF) was introduced, the cell phone has been using contrast focusing (CAF), i.e. continuous autofocus to complete focusing; the focusing time of the focusing mode is long, the lens continuously moves from the beginning of focusing to the end of focusing, and the returning process after the lens passes through the station is to increase the focusing stroke and reflect that the focusing speed is slow for a user. However, contrast focus CAF can be focused up in dim light as compared to phase focus PDAF.

For our part, PDAF and CAF are compatible at the same time, and CAF is used only when PDAF is not effective. The PDAF can be manually opened and closed in the debugging process, and the method is very convenient for debugging and testing personnel: (1) sometimes, focusing effect and speed problems are encountered, and it is difficult to determine whether the problem is a PDAF problem or a CAF problem. This time PDAF needs to be switched on and off in real time to confirm the problem. (2) Evaluation in the product development process requires testing the focusing effect and performance of CAF and PDAF. We are then required to turn PDAFs on and off in real time. (3) The PDAF is turned on or off in real time, so that the function of the PDAF can be conveniently and quickly confirmed whether to be turned on or not. When the existing scheme needs to confirm the problems, two versions of software are required to be compiled: step (1): and developing a modification code, generating two versions of software, and turning on a version one PDAF function and turning off a version two PDAF function. Step (2): testing and finding two mobile phones to respectively download (down) the two versions of software, and carrying out comparison testing; or one mobile phone downloads the two versions of software respectively before and after the comparison test, as shown in the figure.

Fig. 1 is a schematic diagram of a method for closing or opening a PDAF by modifying a code library in the prior art. As shown in fig. 1, in the prior art scheme, a formal software code base is accessed first, and then a PDAF is closed or opened by modifying the code base, that is, the method needs to generate two versions of software. Fig. 2 is a schematic flow chart of opening a PDAF in the prior art. As shown in fig. 2, a specific procedure for opening the PDAF in the prior art is as follows: compiling and generating software for opening the PDA, then, the mobile phone down enters the software for opening the PDAF, and finally, testing the problems. Fig. 3 is a schematic flowchart of closing PDAF in the prior art. As shown in fig. 3, a specific procedure for opening the PDAF in the prior art is as follows: compiling and generating software for closing the PDA, then down the mobile phone as the software for closing the PDAF, and finally testing the problems.

In the prior art, the PDAF is closed or opened by modifying the code base code, different mobile phone system software is compiled, and the problem needs to be tested in a comparison manner for 30-60 minutes, so that the time spent for testing the problem is long, a new technical scheme for switching the PDAF on and off in real time needs to be developed, and the problem needs to be tested and verified in a shorter time.

Detailed Description

In order to understand the features, contents, advantages and effects achieved by the present invention, the present invention is described in detail below in an embodiment form with reference to the accompanying drawings, wherein the main points of the drawings are only schematic and auxiliary for the specification, and are not necessarily true proportions and precise configurations after the implementation of the present invention, and therefore, the present invention should not be interpreted and limited in terms of the proportion and the configuration relationship of the drawings.

The advantages, features and technical measures of the invention will be more readily understood by reference to the following detailed description of exemplary embodiments and the accompanying drawings, and the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.

The method for switching phase focusing in real time is applicable to the case of phase focusing (namely PDAF) + contrast focusing (namely CAF) compatibility. The contrast focusing is used when the phase focusing is not effective, and the phase focusing can be manually opened and closed in the debugging process, so that the method is very convenient for debugging testers.

The principle of contrast focusing is to find the position of the lens with the maximum contrast, i.e. the position of accurate focusing, according to the contrast change of the picture at the focus.

The principle of phase focusing is to reserve some shielding pixel points on the photosensitive element, specially used for phase detection, and determine the focusing offset value through the distance between pixels and the change thereof, thereby realizing accurate focusing. Compared with contrast focusing, the phase focusing does not need repeated movement of a lens, the focusing stroke is much shorter, and the focusing process is clean and not hesitant. On the other hand, the requirement of phase focusing on the light intensity is high because the shielded pixel on the CMOS is needed for phase detection.

However, when the focusing effect and speed problem are encountered, it is difficult to determine whether the phase focusing problem or the contrast focusing problem is solved, and then the phase focusing needs to be switched on and off in real time to confirm the problem, or the focusing effect and performance of the contrast focusing and the phase focusing need to be tested in the product development process. It is necessary to turn on and off the phase focusing in real time, or turn on the phase focusing or turn off the phase focusing in real time can conveniently and quickly confirm whether the function of the phase focusing is turned on or not.

Therefore, the method for switching phase focusing in real time of the present invention is a technical solution applied to confirm the above problems.

In the phase focusing and contrast focusing mode, under the condition of normal light, the focusing speed of the hybrid dual-drive automatic focusing is about 0.1-0.3 seconds, and the photographing is finished for about 2 seconds at the fastest speed theoretically. The presence of the time to focus is hardly felt by the user, which can reach the theoretical 1/15 seconds at the fastest. After the mobile phone is started, phase focusing is carried out immediately, and a focusing frame does not appear. If the focusing point needs to be moved, the traditional focusing mode can be adopted, and the focusing frame is presented at the same time. In brief, the shot photos are transparent and stereoscopic, the portrait is clear and bright, the color is restored to be real, and the problem that good photos cannot be shot in a low-light environment is solved.

Therefore, the most important task of phase focusing is to remove init PD mgr when entering the camera (camera). The basic idea of implementing dynamic switch phase focusing is to dynamically control whether init PD mgr is present by setting corresponding attributes when init PD mgr is present.

Fig. 4 is a schematic flow chart of the method for turning on/off the phase focusing by introducing the PDAF real-time switching function and using the Adb tool. As shown in fig. 4, to confirm the above problem, the method of the present invention for real-time on-off phase focusing includes:

s1: accessing a formal software code base;

s2: importing a real-time switch phase focusing function; the method mainly comprises a function of opening phase focusing and a function of closing phase focusing.

S3: compiling the software of the version, and the mobile phone down enters the software of the version. The software version referred to herein is a software version in which an on/off phase focusing function is introduced.

S4: the phase focus function is switched on and off in real time using the Adb command, i.e. several customized commands are input using the Adb tool to switch the phase focus on and off.

The Adb command is called Android Debug Bridge, and plays a role in debugging the Bridge. With the Adb tool, the state of the device or cell phone simulator can be managed. Many handset operations may also be performed, such as installing software, system upgrades, running shell commands, and so forth. In this embodiment, the Adb tool turns phase focus on or off by entering several customized commands. The customized command corresponds to a function of turning on or off phase focusing.

S5: and performing comparison test on the problems to finish the test process.

From the steps, the function of leading in the phase focusing real-time switch can be clearly seen, the problems of debugging and positioning are convenient, trouble and time are saved, and the method is specifically embodied as follows:

the method for switching phase focusing in real time is obviously different from the prior art, wherein the method in the prior art comprises the following steps: the method comprises the steps of modifying phase focusing related codes in the codes, compiling and generating software for opening phase focusing/closing phase focusing, then conducting down through a mobile phone, and comparing and testing the problems.

Obviously, the invention directly imports the function of real-time switch phase focusing, compiles the software and downloads the software into the software, and the key is to utilize Adb to command the function of real-time switch. Thereby greatly reducing the time for test positioning.

The method for switching phase focusing in real time is implemented based on a Google Android software architecture. The Android is a Linux-based operating system with free and open source codes, and is mainly used for mobile devices such as smart phones and tablet computers. Therefore, the method is used for debugging the code based on the Android system compiling environment.

The Android system is an operating system and a software platform for mobile equipment, and is suitable for the method for switching the phase focusing in real time in the mobile phone. The Android system is based on a Linnux kernel, a user interaction program of the Android system is mainly developed by java language, and the Android system is an open source code. The Android system comprises four components, namely an active component (used for displaying a user interface and monitoring and responding to keys of a user), a service component (without a user interface compared with the active component, and carrying out some monitoring processing or background operation), a content provider component (used for sharing data among a plurality of application programs and providing a uniform data access mode) and a broadcast receiver component (used for receiving necessary actions and responding).

Further, the technical scheme of the invention is realized based on an Android 5.0 system or an Android system with the content of 5.0 or more.

Illustratively, the present invention is MTK platform-based HAL layer code, i.e., the relevant code writing of the present invention involves the HAL layer. The MTK platform adopts a Nucleus OS, the Nucleus is an embedded real-time operating system developed by Accelerated Technology company, and the embedded real-time operating system is developed by using standard C, wherein the Nucleus Plus provides source code downloading. The MTK platform suitable for real-time switch phase focusing of the present invention may be an MT6595 platform, an MT6592WG platform, an MT6592TG platform, an MT6592H platform, an MT6588WG platform, an MT6588TG platform, and the like.

Various attributes of each MTK platform may also be different, for example, a core number attribute, a secondary cache attribute, a DDR attribute, a USB attribute, a core voltage attribute, an encapsulation attribute, a collocation scheme attribute, a 4G scheme attribute, and the like. Therefore, the MTK platform on which the present invention is based is not limited herein, and may be selected according to the specific situation.

The HAL Layer is a Hardware Abstraction Layer (HAL for short), which is a Hardware interface Layer abstracted on a concrete Hardware platform, and the interface Layer is responsible for realizing the functions and control of the concrete Hardware platform and providing a uniform API interface for other software modules. The HAL layer is created to abstract the commonality of hardware operation and control, and to provide a unified control interface to upper layer software to isolate other software modules from the underlying hardware. With the HAL, the migration of the system on a new hardware platform becomes extremely simple, and the whole eCOs system including the application based on the eCOs can be migrated on the new hardware platform only by providing an abstraction layer of new hardware.

The HAL layer is an adaptation layer added by Goold, which is required by some manufacturers not to disclose source codes, and can provide a hardware driving module in a source code closing mode, so that an Android frame layer (Android framework layer) and a linux kernel layer (driving layer) are isolated, an Android system is prevented from being excessively dependent on the realization of the linux kernel layer (driving layer), and the Android framework layer can be independently developed without considering how the driving layer is realized. Wherein the Android HAL layer is positioned between the Android system and the driving layer.

When a system is transplanted or a new module is added, the HAL layer of the Android needs to be modified or added, and the HAL layer of the Android is located at the source code position of the Android: for example, hardware/libhardware/; alternatively, hardware/libhardware _ legacy/; or hardware/xxxx/. And some at other locations. The android hal layer can be implemented in several ways, such as a hardware module way, a C/C + + inheritance way, a direct call driving interface way, or a direct interface way.

As described above, since the method for real-time switch phase focusing of the present invention is different from the prior art, the corresponding module structure for real-time switch phase focusing of the present invention is different from the module structure for switching on or off phase focusing in the prior art.

Fig. 7 is a schematic structural diagram of a module of the real-time PDAF switch according to the present invention.

As shown in fig. 7, the system for switching PDAF in real time according to the present invention comprises: the device comprises an import module 1, a compiling and downloading module 2, an Adb command execution module 3 and a comparison module 4.

The method is realized based on an Android property (property) mechanism and an Adb command. The operation mechanism of the Property mechanism includes: a. when the system is started, the attribute content can be loaded from a plurality of attribute script files; b. all attributes (key/value) in the system are stored in the same shared memory block; c. each process in the system maps the shared memory to the memory space of the process, so that the attribute content can be directly read; d. only one entity in the system can set and modify the attribute value, which is the attribute Service (Property Service); e. different processes can only send a request for modifying the attribute value to the attribute service in a socket mode, but cannot directly modify the attribute value; f. the key-value content in the shared memory is organized in a dictionary tree. The Property Service entity is actually started in the init process. Wherein init is the first process of the user space in the Linux system. It is responsible for creating the most critical sub-processes in the system, such as zygate, etc.

b. the debug person can control the debug, pdaf, onoff attribute in real time through the Adb command, so as to dynamically set the value of the pool variable debug _ pdaf _ onoff.

db shell setprop debug, PDAF, onoff 1 — turn on PDAF;

adb shell setprop debug, PDAF, onoff 0- - -turn off PDAF

c. The code judges whether init PD mgr is needed according to the value of the pool variable.
