In order to make those skilled in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application shall fall within the scope of the protection of the embodiments in the present application.
The following further describes specific implementations of embodiments of the present application with reference to the drawings of the embodiments of the present application.
Fig. 1 is a schematic flowchart of an image processing method according to an embodiment of the present disclosure; as shown in fig. 1, it includes:
s101, obtaining an image to be enhanced with a set image code rate;
in this embodiment, the image to be enhanced is generated by a pan-tilt camera. Therefore, when the step S101 is executed, the to-be-enhanced image with the set image code rate is obtained locally from the pan-tilt camera; in addition, in other embodiments, the image to be enhanced may also be obtained from a cloud or other devices in which the image to be enhanced is stored.
For example, in an application scenario, if the image to be enhanced is stored in an image capturing device, and the step S101 is executed on the side of an electronic device connected to the image capturing device, the step S101 may specifically be: and obtaining an image to be enhanced with a set image code rate from the image shooting equipment, wherein the image to be enhanced is generated by the pan-tilt camera. For this purpose, an image to be enhanced having a set image code rate is obtained from an image capturing apparatus in a wired or wireless manner, the image to be enhanced being generated by a pan-tilt camera. For the wired mode, the electronic device and the image shooting device can be connected through a physical communication interface, so that a wired communication channel is established, an image to be enhanced with a set image code rate is obtained through the wired communication channel, the image to be enhanced is generated by the pan-tilt camera, and the physical interface is, for example, a USB interface, a Type C interface and the like. For a wireless mode, for example, by configuring bluetooth modules on the electronic device and the image capturing device, the electronic device and the image capturing device may be connected through the bluetooth modules, so as to establish a wireless communication channel, and obtain an image to be enhanced with a set image bitrate through the wireless communication channel, where the image to be enhanced is generated by the pan-tilt camera. Of course, it should be noted here that the wireless mode is not particularly limited to be implemented by a bluetooth module, and in fact, the wireless mode may also be implemented based on Wifi, which is not described in detail.
For another example, in another application scenario, if the image to be enhanced is stored in an image capturing device, and the step S101 is executed on the side of the image capturing device, the step S101 may specifically be: the method comprises the steps of obtaining an image to be enhanced with a set image code rate from an image shooting device locally, wherein the image to be enhanced is generated by a pan-tilt camera.
Optionally, in this embodiment, a format of the image to be enhanced is not particularly limited, and may be, for example: bmp, jpg, png, tif, gif, pcx, tga, exif, fpx, svg, psd, cdr, pcd, dxf, ufo, eps, ai, raw, WMF, and webp. If the image to be enhanced is required to have a set format in a specific application scene, the image to be enhanced with the set format can be obtained through image format conversion.
In this embodiment, the image to be enhanced may be a video or a picture. If the video is a video, the video can be a video segment in a complete video, or the complete video.
S102, according to the image enhancement request, enhancing the image to be enhanced to generate an enhanced image, wherein the quality index of the enhanced image is matched according to the set image code rate.
Optionally, in this embodiment, the image enhancement request is triggered by hardware or software. For example, in an application scenario, if the step S102 is executed on the side of the electronic device, an entity key may be configured on the electronic device, where the entity key may reuse an existing key on the electronic device, or may trigger an additionally added entity key for implementing hardware. And the user operates the entity key to realize that the hardware triggers the image enhancement request. For another example, in another application scenario, if the step S102 is still executed on the side of the electronic device, a virtual key may be configured on a display interface of the electronic device, where the virtual key may reuse an existing key on the electronic device, or may trigger an additional virtual key for implementing software.

For example, an original image shot by a pan-tilt camera is compressed to obtain an image to be enhanced. When the original image shot by the pan-tilt camera is compressed, a larger image code rate can be used for compression, and the larger image code rate is, for example, relative to the image code rate used when the original image is compressed during normal preview on the intelligent terminal. Therefore, when the scheme provided by the embodiment of fig. 1 is applied to an intelligent terminal to operate, the obtained image to be enhanced can be closer to the original image shot by the pan-tilt-zoom camera because the image code rate used in the compression processing is larger, so that the scheme provided by the embodiment of fig. 1 is executed in the intelligent terminal, and the generated enhanced image has higher quality indexes, such as higher image resolution and lower image distortion, therefore, in the process of the enhancement processing, the association relationship is established between the image code rate and the quality index of the image, so that the processing process of the enhancement processing is controllable, and finally the difficulty of the enhancement processing is reduced.
Of course, in some other application scenarios, when the original image shot by the pan-tilt camera is compressed, a smaller image code rate may be used for compression, where the smaller image code rate is, for example, relative to the image code rate used when the original image is compressed during normal preview on the intelligent terminal, so that the generated enhanced image has a lower quality index.

S103, performing preview processing on the enhanced image according to the image preview request.
In this embodiment, if the electronic device executes the above steps S101 to S103, the image preview request is generated by the electronic device, for example, an entity key or a virtual key is provided on the electronic device, and the user triggers the image preview request by operating the entity key or the virtual key, so as to finally preview the enhanced image on the electronic device.

In this embodiment, the image to be enhanced may be a video or a picture. If the video is a video, the video can be a video segment in a complete video, or the complete video.
Optionally, in this embodiment, the image enhancement request is triggered by hardware or software.

For convenience of understanding of the technical solutions provided in the embodiments of the present application, the technical solutions provided in the embodiments of the present application are exemplarily described herein with reference to specific application scenarios, but it should be noted herein that the technical solutions provided in the embodiments of the present application are not limited to be only applicable to the specific application scenarios described below.
Fig. 6 is a schematic view of an application scenario provided in a sixth embodiment of the present application; as shown in fig. 6, in this embodiment, the application scene includes a pan-tilt camera and an intelligent terminal, where the pan-tilt camera is used to take a picture of a target object to obtain an original image, and the original image may be understood as image data output by an image sensor in the camera, such as in a DNG format or other formats, and the original image or also referred to as a digital film retains more image information and has higher image quality.
In this embodiment, because the display screen of the pan-tilt camera is generally small and the image preview effect is poor, the display screen of the intelligent terminal is generally large and the image preview effect is good, so that the image to be enhanced is enhanced on the intelligent terminal, and the image can be previewed on the large display screen to improve the image preview effect.
Furthermore, because the image of the original image is large, the data volume of the file is large, and the file is difficult to transmit to the intelligent terminal in real time and is directly used as the image to be enhanced. In the compression process, in order to enable the compressed image as the image to be enhanced to have the quality index as close to the original image as possible, when the original image is compressed, the image code rate as large as possible is set to reserve more image information, so that the loss of the image information of the compressed image as the image to be enhanced is less, the quality index of the compressed image is further enabled to be closer to the quality index of the original image, the image quality of the enhanced image obtained after the enhancement process is also higher, and a good image preview effect is further achieved.
Here, it should be noted that the image code rate as large as possible may be larger than the image code rate used when compressing the image to be compressed in order to satisfy the normal preview image (in various situations except the preview enhanced image, such as the video recording mode situation) on the smart terminal, for example.
The intelligent terminal obtains the image to be enhanced in a wired or wireless mode, generates an image enhancement request according to hardware triggering or software triggering, and then performs enhancement processing on the image to be enhanced according to the image enhancement request to generate an enhanced image. The method comprises the steps of compressing a camera, generating an enhanced image, previewing the enhanced image, and performing electronic zooming on the enhanced image to match or approximate to the original image in the aspect of picture ratio, wherein the image code rate which can meet the requirement of performing enhancement processing on an intelligent terminal is used when the camera is compressed, so that more image information is reserved in the generated enhanced image, the image quality is higher, and a good image previewing effect is achieved when the image is previewed.
In this embodiment, the enhanced image may be stored locally in the intelligent terminal, so as to be directly obtained locally from the intelligent terminal during preview.
In an application scenario, the above image processing method may also be executed on a camera, and for this reason, unlike the above embodiment, the original image is compressed locally by using a set image code rate to obtain an image to be enhanced, and the image to be enhanced is enhanced locally by the camera according to an image enhancement request to generate an enhanced image, so that the enhanced image is previewed locally on the camera, and the enhanced image is directly stored locally on the camera.
In addition, in another scene, the image processing method can be realized locally, namely the image processing method can be realized locally in a camera, and the image processing method can also be realized locally in an intelligent terminal; when the image processing method is locally realized from the camera to the intelligent terminal, the display screen of the camera can not display the content or is in a screen-off state, so that the power consumption of the camera is saved.
Further, in order to implement the image enhancement processing method on the smart terminal, an application program (APP in the industry) may be installed on the smart terminal, and a user starts the APP to trigger the execution of the image processing method.
Further, the camera may be a pan-tilt camera or a motion camera, and the intelligent terminal may be a smart phone or the like.
Further, in some other application scenarios, the image to be enhanced may be acquired from a cloud.
Thus, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the storage unit controller may also be implemented as part of the control logic of the storage unit. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
