In one embodiment, an image processing method is provided for application to the electronic device described above for illustration, and as shown in fig. 2, the information processing method includes steps 202 to 204. Wherein:
A thread is a single sequential control flow through which an electronic device can run a program. There may be multiple threads in an electronic device, running different programs, respectively. Wherein multiple threads may run simultaneously. The photographing instruction may be an instruction for instructing the electronic device to photograph an image. For example, when a user clicks a shooting control in a display screen of the electronic device, the electronic device may generate a shooting instruction; when a user presses a photographing button in the electronic device, the electronic device may generate a photographing instruction.
The first thread is a thread that allows access to an Interface control of the electronic device, for example, the first thread may be a UI (User Interface) thread, and may be another thread that allows access to an Interface control of the electronic device, which is not limited herein. The second thread is a thread that prohibits access to an interface control of the electronic device. The original image refers to an unprocessed image acquired by the camera.
When the first thread receives the shooting instruction, the electronic device can shoot an original image on the first thread. The electronic device may send the captured original image to the second thread via the first thread.
And 204, performing second processing on the original image through a second thread to obtain a second target image.
The second process may be image processing of the original image, for example, light effect processing, blurring processing, beautifying processing, or the like. After the electronic device sends the original image to the second thread through the first thread, the electronic device can perform second processing on the original image through the second thread to obtain a second target image. For example, the electronic device performs light effect processing on the original image through the second thread, and the obtained second target image may be a light effect image.
When the first thread receives a shooting instruction, the original image obtained through shooting is sent to a second thread through the first thread, wherein the first thread is a thread allowing access to the interface control of the electronic equipment, the second thread is a thread prohibiting access to the interface control of the electronic equipment, and the second thread carries out second processing on the original image to obtain a second target image. The first thread sends the shot original image to the second thread, and the second thread carries out second processing, because the first thread is a thread allowing access to the interface control of the electronic equipment, and the second thread is a thread prohibiting access to the interface control of the electronic equipment, the second processing of the image through the second thread can not be displayed in the interface of the electronic equipment, and when the second thread processes the image, a user can continue to carry out other operations on the electronic equipment, so that the operation efficiency of the electronic equipment is improved.
As shown in fig. 3, in one embodiment, the provided image processing method may further include a process of sending the original image to the second thread, and the specific steps include:
in step 302, when the first thread receives the shooting instruction, a shooting mode corresponding to the shooting instruction is obtained.
The shooting mode may be a mode for capturing an image in the electronic device. For example, the shooting mode may be a time-lapse shooting mode, a slow motion mode, a video mode, a photo mode, a panoramic mode, or the like. The shooting mode corresponding to the shooting instruction can be a shooting mode selected by a user when an image is acquired, or can be a shooting mode switched by the electronic equipment when the image is acquired. When the first thread receives the shooting instruction, the electronic device can acquire a shooting mode corresponding to the shooting instruction. For example, when the shooting mode selected by the user is a video mode and the user clicks a control on the display screen of the electronic device to generate a shooting instruction, the first thread can receive the shooting instruction, and the electronic device can acquire the shooting mode corresponding to the shooting instruction as the video mode.
In step 304, when the shooting mode is the first shooting mode, the original image obtained by shooting is sent to the second thread through the first thread.
After the electronic device obtains the shooting mode corresponding to the shooting instruction, whether the obtained shooting mode is the first shooting mode or not can be judged. The first shooting mode may be set by a user through the electronic device, or may be divided by the electronic device according to the stored shooting modes. For example, the first photographing mode may be a photograph mode, a panorama mode, or the like.
When the acquired shooting mode is the first shooting mode, the electronic device can send the original image obtained through shooting to the second thread through the first thread. For example, the shooting mode acquired by the electronic device is a photo mode, and the first shooting mode in the electronic device is a photo mode or a panoramic mode, so that the electronic device can send the original image obtained by shooting to the second thread through the first thread.
And 306, when the shooting mode is the second shooting mode, performing second processing on the shot original image through the first thread to obtain a second target image.
The second photographing mode may be set by the user through the electronic device, or may be divided by the electronic device according to photographing modes already stored. For example, the second photographing mode may be a time-lapse photographing mode, a slow motion mode, a video mode, or the like. When the shooting mode acquired by the electronic equipment is the second shooting mode, the electronic equipment can perform second processing on the original image obtained through shooting through the first thread, and a second target image is obtained.
In this embodiment, when the first thread receives the shooting instruction, a shooting mode corresponding to the shooting instruction is acquired, when the shooting mode is the first shooting mode, the first thread sends the original image obtained by shooting to the second thread, and when the shooting mode is the second shooting mode, the first thread performs second processing on the original image obtained by shooting to obtain the second target image. After the electronic equipment acquires the shooting mode, different threads can be selected according to the shooting mode to perform second processing on the original image, so that the operation efficiency of the electronic equipment is improved, and meanwhile, the processing efficiency of the image can also be improved.
In another embodiment, as shown in fig. 4, the provided image processing method may further include a process of sending the original image to the second thread, and the specific steps include;
Threads in electronic devices can be in different states, and the threads have three basic states of idle, blocking and running. The idle state of the thread refers to all conditions of the thread with running, and the thread can logically execute when waiting to run; the blocked state of a thread means that the thread is logically non-executable while waiting for an event; the running state of a thread refers to the thread running a program.
The electronic device may detect a state of the second thread. In particular, the electronic device may detect whether there is a second thread in an idle state.
And when the second thread in the idle state exists as a result of detection of the electronic equipment, the second thread with all running conditions exists in the electronic equipment, and the electronic equipment waits for running. The electronic device can send the photographed original image to a second thread in an idle state through the first thread, and the second thread in the idle state carries out second processing on the original image to obtain a second target image.
In step 406, when there is no second thread in idle state in the electronic device, a new second thread is established, and the captured original image is sent to the new second thread through the first thread.
And when the detected result of the electronic equipment is that the second thread in the idle state does not exist, the electronic equipment indicates that the second thread capable of running does not exist in the electronic equipment, and the electronic equipment can establish a new second thread. After the new second thread is established, the electronic device can send the original image obtained through shooting to the new second thread through the first thread, and the second processing is carried out on the original image through the new second thread to obtain a second target image.
In this embodiment, by detecting whether a second thread in an idle state exists in the electronic device, when the second thread in the idle state exists in the electronic device, the first thread sends the captured original image to the second thread in the idle state, and when the second thread in the idle state does not exist in the electronic device, a new second thread is established, and the first thread sends the captured original image to the new second thread. The electronic equipment detects whether the second thread is in the idle state or not, and when the second thread in the idle state does not exist in the electronic equipment, a new second thread is built, the second thread in the idle state in the electronic equipment is fully utilized, and the resource utilization rate of the electronic equipment is improved.
As shown in fig. 5, in one embodiment, the provided image processing method may further include a process of processing an original image, including the following specific steps:
There may be a plurality of second threads in the electronic device. When there is no second thread in the idle state in the electronic device, the electronic device may count the number of threads of the second thread.
And step 504, when the number of threads is smaller than the number threshold, a new second thread is established, and the photographed original image is sent to the new second thread through the first thread.
The number threshold may be set by a user, or may be set by the electronic device according to the operation condition of the system thereof. The quantity threshold is a specific value, for example, the quantity threshold may be a value of 3, 5, 6, etc.
After the electronic device counts the number of threads of the second thread, the counted number of threads of the second thread may be compared with a number threshold, and when the number of threads of the second thread is smaller than the number threshold, the electronic device may establish a new second thread. For example, the electronic device may acquire the number of threads of the second thread as 3, the number threshold as 4, and the number of threads of the second thread is less than the number threshold, and the electronic device may establish a new second thread. After the new second thread is established, the electronic device can send the photographed original image to the new second thread through the first thread, and the original image is processed through the new second thread.
And step 506, when the number of threads is greater than or equal to the number threshold, performing second processing on the photographed original image by the first thread to obtain a second target image.
When the electronic device compares the number of threads of the second threads with the number threshold value to obtain a result that the number of threads is larger than or equal to the number threshold value, the electronic device indicates that more second threads exist in the electronic device and can perform second processing on the photographed original image through the second threads to obtain a second target image.
In this embodiment, when there is no second thread in an idle state in the electronic device, counting the number of threads of the second thread in the electronic device, when the number of threads is smaller than a number threshold, establishing a new second thread, sending the original image obtained by shooting to the new second thread through the first thread, and when the number of threads is greater than or equal to the number threshold, performing a second process on the original image obtained by shooting through the first thread, so as to obtain a second target image. When the second thread in the idle state does not exist in the electronic equipment, whether a new second thread is established or not is determined according to the number of threads of the second thread, and the processing of the original image is determined by which thread, so that the burden of the electronic equipment is reduced.
In one embodiment, as shown in fig. 6, the provided image processing method may further include a process of storing the target image, and the specific steps include:
In step 602, a first process is performed on an original image by a first thread, so as to obtain a first target image.
The first process may be a simplified process of the original image by the electronic device through the first thread. After the first thread receives the shooting instruction, the electronic device can perform first processing on the original image obtained through shooting through the first thread, and a first target image is obtained.
After obtaining the first target image, the electronic device may store the first target image. Specifically, the electronic device may store the first target image in an image library, e.g., the electronic device may store the first target image in an album.
And step 606, performing second processing on the original image through a second thread, wherein the duration consumed by the first processing is smaller than the duration consumed by the second processing.
The second process may be a refinement process of the original image by the electronic device through the second thread. The electronic device performs first processing on the original image through the first thread, and the time consumed by the electronic device for performing second processing on the original image through the second thread is smaller than the time consumed by the electronic device for performing first processing on the original image through the second thread.
And 608, when the second processing is detected to be completed, replacing the first target image with the second target image obtained according to the second processing and storing the second target image.
The electronic device may detect a processing progress of the first process and the second process. When the electronic device detects that the second process is completed, the electronic device may obtain a second target image. The electronic device may store the second target image in place of the first target image. For example, the electronic device may store a first target image obtained by performing a first process on an original image by the first thread in the album, and when the electronic device detects that the second process is completed, the electronic device may store the obtained second target image in the album instead of the first target image, that is, the electronic device may delete the first target image from the album and store the second target image in the album.
In this embodiment, a first process is performed on an original image through a first thread to obtain a first target image, the first target image is stored, a second process is performed on the original image through a second thread, wherein the duration consumed by the first process is smaller than the duration consumed by the second process, and when the second process is detected to be completed, the second target image obtained according to the second process is stored in place of the first target image. The electronic device performs first processing on the original image through the first thread and performs second processing on the original image through the second thread, and as the two threads process the original image at the same time, the time consumed by the second processing is longer than that consumed by the first processing, the image obtained by the second processing is more accurate, the more accurate image is stored in the electronic device, and the accuracy of image processing is embodied. Because the second processing consumes longer time, the electronic device can store the first target image obtained by the first processing in the electronic device, when the electronic device acquires the original image and the user needs to immediately check the image, the electronic device can display the stored first target image to the user, and the waiting time when the user needs to immediately check the image is reduced.
In one embodiment, the image processing method provided may further include a process of displaying the thumbnail, and specifically includes: and compressing the first target image to generate a corresponding thumbnail, and displaying the thumbnail in an interface of the electronic equipment.
After the electronic device acquires the first target image, the electronic device may perform compression processing on the first target image and generate a corresponding thumbnail. The electronic device may display the generated thumbnail in an interface. Specifically, the position of the electronic device for displaying the thumbnail in the interface may be set by the user, or may be a default position of the electronic device.

The first light effect model and the second light effect model are models simulating light changes. For example, the first and second light effect models may be natural light effect models, contour light effect models, stage light effect models, background blurring models, and the like. The first light effect model is a natural light effect model, and the second light effect model is a natural light effect model, and the first light effect model is a natural light effect model, and the resource occupancy rate of the first light effect model is smaller than the resource occupancy rate of the second light effect model. The resource occupancy refers to the size of the resources occupied by the program at runtime, for example, the resource occupancy may be 40%, 43%, 65%, etc. The resource occupancy rate may be a CPU occupancy rate, a memory occupancy rate, a storage space occupancy rate, or the like, which is not limited herein.

The imaging device 910 may include a camera having one or more lenses 912 and an image sensor 914. The image sensor 914 may include a color filter array (e.g., bayer filters), and the image sensor 914 may obtain light intensity and wavelength information captured with each imaging pixel of the image sensor 914 and provide a set of raw image data that may be processed by the ISP processor 940. The sensor 920 (e.g., gyroscope) may provide parameters of the captured image processing (e.g., anti-shake parameters) to the ISP processor 940 based on the type of sensor 920 interface. The sensor 920 interface may utilize an SMIA (Standard Mobile Imaging Architecture ) interface, other serial or parallel camera interfaces, or a combination of the above.

For example, each image pixel may have a bit depth of 8, 10, 12, or 14 bits, and ISP processor 940 may perform one or more image processing operations on the raw image data, collecting statistical information about the image data. Wherein the image processing operations may be performed with the same or different bit depth precision.
Upon receiving raw image data from the image sensor 914 interface or from the sensor 920 interface or from the image memory 930, the ISP processor 940 may perform one or more image processing operations, such as temporal filtering. The processed image data may be sent to image memory 930 for additional processing before being displayed. ISP processor 940 receives the processed data from image memory 930 and processes the processed data for image data in the original domain and in the RGB and YCbCr color spaces. The image data processed by ISP processor 940 may be output to display 970 for viewing by a user and/or further processing by a graphics engine or GPU (Graphics Processing Unit, graphics processor). Further, the output of ISP processor 940 may also be sent to image memory 930, and display 970 may read image data from image memory 930. In one embodiment, the image memory 930 may be configured to implement one or more frame buffers. In addition, the output of ISP processor 940 may be sent to encoder/decoder 960 in order to encode/decode image data. The encoded image data may be saved and decompressed prior to display on the display 970 device. Encoder/decoder 960 may be implemented by a CPU or GPU or co-processor.
