[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] In one embodiment, Figure 1 As shown, an image processing method is provided. This embodiment uses the method applied to an electronic device as an example for illustration. The electronic device may be a terminal or a server. It is understandable that the method may also be applied to a system including a terminal and a server, and implemented through the interaction between the terminal and the server. Among them, the terminal may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The server may be an independent physical server, a server cluster or a distributed system consisting of multiple physical servers, or a cloud server that provides cloud computing services.

[0052] In this embodiment, the image processing method includes the following steps:

[0053] Step S102: In the underwater mode, the shooting picture is displayed.

[0054] The underwater mode is a mode in which the electronic device performs image processing in water.

[0055] Optionally, when the electronic device detects that it is in water, it enters underwater mode.

[0056] Optionally, the electronic device enters the underwater mode in response to a trigger operation of the underwater mode.

[0057] Optionally, in the underwater mode, the electronic device responds to a trigger operation of the camera application, opens the camera application, and displays the captured image.

[0058] Optionally, when the electronic device enters the underwater mode, the underwater mode thread is started, and the shooting picture is displayed in the underwater mode thread. The fingerprint can be recognized more efficiently through the underwater mode thread.

[0059] Step S104, in response to the first touch operation, obtaining first fingerprints continuously collected a target number of times during the first touch operation, and determining a zoom event according to the first fingerprints of the target number of times.

[0060] The first touch operation is an operation for determining a zoom event. The target number is the number of first fingerprints collected during the first touch operation. The first fingerprint is a fingerprint collected during the first touch operation. The zoom event is an event for zooming in and out of a captured image. Optionally, the zoom event includes a zoom-out event or a zoom-in event.

[0061] Optionally, the captured image includes a fingerprint area, and the electronic device responds to a first touch operation on the fingerprint area by acquiring a first fingerprint continuously collected a target number of times during the first touch operation at a target sampling frame rate, wherein the target sampling frame rate can be set as needed.

[0062] The electronic device obtains a preset first sampling frame rate, increases the first sampling frame rate, and obtains a target sampling frame rate. For example, the electronic device increases the preset first sampling frame rate, that is, shortens the frame rate time of the first sampling frame rate by 2 / 3, so that the fingerprint image can be collected faster and the fingerprint recognition performance can be improved.

[0063] Optionally, when the target number of times is greater than a number threshold, a zoom event is determined according to the first fingerprint of the target number of times. The number threshold can be set as needed, such as 10.

[0064] Step S106, in response to the zoom event, zoom the captured image.

[0065] Optionally, if the zoom event is a zoom-out event, the captured image is zoomed out in response to the zoom-out event.

[0066] Optionally, if the zoom event is a magnification event, the captured image is magnified in response to the magnification event.

[0067] Optionally, the electronic device zooms the captured image to obtain the zoomed captured image; and in response to the third touch operation, the zoomed captured image is photographed to obtain a target image or a target video. The third touch operation is an operation for photographing the zoomed captured image.

[0068] Optionally, in response to the third touch operation on the fingerprint area, the electronic device shoots the zoomed shot to obtain a target image or a target video.

[0069] The above-mentioned image processing method, in the case of underwater mode, displays the shooting picture, responds to the first touch operation, obtains the first fingerprint of the target number of continuous collections during the first touch operation, then, according to the first fingerprint of the target number of times, the zoom event can be accurately determined, and in response to the zoom event, the zoom processing of the shooting picture can be accurately realized, thereby realizing the zoom processing of the shooting picture underwater. In addition, the electronic device can perform more accurate image processing on some close-up objects underwater to obtain clearer and higher quality shooting images.

[0070] In one embodiment, determining a zoom event according to a first fingerprint of a target number of times includes: matching the first fingerprint with a reference fingerprint; if the first fingerprint matches the reference fingerprint and the target number of times is greater than a number threshold, determining a zoom event according to the first fingerprint of the target number of times.

[0071] The reference fingerprint is a fingerprint used for reference when matching fingerprints. Optionally, the reference fingerprint can be stored locally in the electronic device or in a cloud server.

[0072] Optionally, the electronic device matches the first fingerprint with a reference fingerprint, determines a first similarity between the first fingerprint and the reference fingerprint, and determines a matching result between the first fingerprint and the reference fingerprint based on the first similarity.

[0073] If the first similarity is greater than or equal to the first similarity threshold, it is determined that the first fingerprint matches the reference fingerprint; if the first similarity is less than the first similarity threshold, it is determined that the first fingerprint does not match the reference fingerprint. The first similarity threshold can be set as needed.

[0074] Optionally, if the first fingerprint and the reference fingerprint do not match, a prompt message is displayed. The prompt message is used to indicate that the first fingerprint does not match.

[0075] Optionally, before matching the first fingerprint with the reference fingerprint, the method further includes: improving a preset first fingerprint false recognition rate to obtain a second fingerprint false recognition rate; matching the first fingerprint with the reference fingerprint includes: matching the first fingerprint with the reference fingerprint according to the second fingerprint false recognition rate.

[0076] Among them, FAR (FALSE ACCETANCE RATA) is the false recognition rate, that is, the probability that the fingerprint of the non-reference fingerprint owner matches the reference fingerprint. The lower the false recognition rate, the lower the probability that the fingerprint of the non-reference fingerprint owner matches the reference fingerprint, that is, the safer the fingerprint unlocking is. The first fingerprint false recognition rate is the fingerprint false recognition rate preset by the electronic device in normal mode. The second fingerprint false recognition rate is the fingerprint false recognition rate of the electronic device in underwater mode.

[0077] It is understandable that when an electronic device is underwater, the fingerprint recognition rate is less than 50%, usually only 10%. In order to improve the fingerprint recognition success rate and increase the preset first fingerprint false recognition rate, the fingerprint recognition success rate can be controlled to above 99%, and image processing can be performed more accurately, greatly improving the user experience.

[0078] Optionally, after scaling the captured image, the method further includes: the electronic device obtains the scaling ratio of the captured image, adjusts the second fingerprint false recognition rate based on the scaling ratio, and obtains a new second fingerprint false recognition rate; when a new third fingerprint is obtained, the third fingerprint is matched with the reference fingerprint according to the new second fingerprint false recognition rate.

[0079] It is understandable that different zoom ratios correspond to different fingerprint false recognition rates, and the fingerprint false recognition rate can be adjusted in real time according to different zoom ratios to improve the success rate of image acquisition.

[0080] Optionally, after scaling the captured image, the method further includes: if the captured image is reduced in size, the second fingerprint false recognition rate is adjusted to obtain the second fingerprint false recognition rate corresponding to the reduced size; if the captured image is enlarged in size, the second fingerprint false recognition rate is adjusted to obtain the second fingerprint false recognition rate corresponding to the enlarged size.

[0081] It is understandable that the enlargement processing and the reduction processing correspond to different fingerprint false recognition rates, and the enlargement processing and the reduction processing can be distinguished more accurately to improve the success rate of image acquisition and perform image processing more accurately.

[0082] Optionally, if the first fingerprint matches the reference fingerprint and the target number is greater than the number threshold, a zoom event is determined based on the first fingerprint of the target number, including: if the first fingerprint matches the reference fingerprint and the target number is greater than the number threshold, determining the number of pollings at which the target number of polls reaches the number threshold; if the polling number is an odd number, determining that the zoom event corresponding to the polling number is a zoom-out event; if the polling number is an even number, determining that the zoom event corresponding to the polling number is a zoom-in event.

[0083] Wherein, the polling number is the number of times the target polling number reaches the number threshold value. For example, the number threshold value is 10, if the target number is 15, then the polling number of times the target polling number reaches the number threshold value is 1, if the target number is 23, then the polling number of times the target polling number reaches the number threshold value is 2, if the target number is 58, then the polling number of times the target polling number reaches the number threshold value is 5.

[0084] Exemplarily, the number threshold is 10. If the target number is 15, the target number of polls reaches the number threshold for polling, which is 1. A zoom-out event is determined, and the captured image is zoomed out. If the target number is 23, the target number of polls reaches the number threshold for polling, which is 2. A zoom-in event is determined, and the captured image is zoomed in. If the target number is 58, the target number of polls reaches the number threshold for polling, which is 5. A zoom-out event is determined, and the captured image is zoomed out.

[0085] Optionally, if the polling number is an even number, the zoom event corresponding to the polling number is determined to be a zoom-out event; if the polling number is an odd number, the zoom event corresponding to the polling number is determined to be a zoom-in event.

[0086] In this embodiment, the electronic device matches the first fingerprint with the reference fingerprint. If the first fingerprint matches the reference fingerprint and the target number of times is greater than the number threshold, the zoom event can be determined more accurately according to the first fingerprint of the target number of times.

[0087] Furthermore, the electronic device improves a preset first fingerprint false recognition rate to obtain a second fingerprint false recognition rate, and matches the first fingerprint with the reference fingerprint according to the second fingerprint false recognition rate.

[0088] Further, if the first fingerprint matches the reference fingerprint and the target number of polls is greater than the number threshold, the target number of polls is determined to reach the polling number threshold, and the zoom event is accurately determined to be a zoom-in event or a zoom-out event according to whether the polling number is an odd number or an even number.

[0089] In one embodiment, Figure 2As shown, another image processing method is provided, which includes an underwater camera sub-process and a fingerprint compression and zoom sub-process; in the underwater camera sub-process, the electronic device executes step S202 to enter the underwater mode; executes step S204 to start the underwater mode thread and display the shooting picture, which includes the fingerprint area; executes step S206 to obtain the first fingerprint in response to the pressing operation on the fingerprint area. In the fingerprint compression and zoom sub-process, the false recognition rate algorithm is designed, that is, the preset first fingerprint false recognition rate is improved to obtain the second fingerprint false recognition rate, then the electronic device executes step S208 to match according to the second fingerprint false recognition rate; if the first fingerprint matches the reference fingerprint, and the target number of times is greater than the number threshold, then the zoom event is determined according to the first fingerprint of the target number, and step S210 is executed in response to the zoom event to enlarge or reduce the shooting picture.

[0090] In one embodiment, Figure 3 As shown, the electronic device executes step S302, enters the underwater mode, and displays the shooting picture; executes step S304, improves the preset first fingerprint false recognition rate, and obtains the second fingerprint false recognition rate; executes step S306, obtains the target sampling frame rate; executes step S308, in response to the first touch operation, obtains the first fingerprint according to the target sampling frame rate; executes step S310, performs fingerprint matching according to the second fingerprint false recognition rate, and determines whether the number of consecutive successful matches between the first fingerprint and the reference fingerprint is greater than 10; if the number of consecutive unlocking times of the fingerprint is less than or equal to 10, executes step S312, and continues to preview the shooting picture; if the number of consecutive unlocking times of the fingerprint is greater than 10, that is, the fingerprint matches the reference fingerprint and the consecutive unlocking is greater than 10, then executes step S314 to scale the shooting picture.

[0091] In one embodiment, in underwater mode, a captured picture is displayed, including: in underwater mode, a desktop interface is displayed; the desktop interface includes a fingerprint area; in response to a second touch operation on the fingerprint area, a second fingerprint of the second touch operation is obtained; if the second fingerprint matches the reference fingerprint, a camera application is started and the captured picture is displayed.

[0092] The fingerprint area can be set at any position in the desktop interface, such as the center, the lower center, the left or right edge of the desktop interface, etc. The fingerprint area has no light spot.

[0093] Optionally, the electronic device sets different contrasts between the fingerprint area and other areas of the screen to display the fingerprint area on the screen. It is understandable that the conventional fingerprint area is marked with a light spot, while the fingerprint area is marked with a screen contrast difference in this embodiment, and the fingerprint information can be more accurately obtained through the fingerprint area.

[0094] Optionally, the electronic device matches the second fingerprint with the reference fingerprint, determines a second similarity between the second fingerprint and the reference fingerprint, and determines a matching result between the second fingerprint and the reference fingerprint based on the second similarity.

[0095] If the second similarity is greater than or equal to the second similarity threshold, it is determined that the second fingerprint matches the reference fingerprint; if the second similarity is less than the second similarity threshold, it is determined that the second fingerprint does not match the reference fingerprint. The second similarity threshold can be set as needed.

[0096] Optionally, if the second fingerprint does not match the reference fingerprint, a prompt message is displayed. The prompt message is used to indicate that the second fingerprint does not match.

[0097] Optionally, displaying the desktop interface in the underwater mode includes: in the underwater mode, increasing a preset first brightness to obtain a second brightness; and displaying the desktop interface at the second brightness.

[0098] Among them, the preset first brightness is the screen brightness in normal mode.

[0099] Optionally, in underwater mode, the electronic device obtains a preset first brightness, increases the first brightness to obtain a second brightness, and displays the desktop interface at the second brightness, so that the captured image information and fingerprint area location can be more clearly obtained underwater, thereby more accurately acquiring the fingerprint for image processing.

[0100] In this embodiment, in the underwater mode, a desktop interface is displayed, which includes a fingerprint area; in response to a second touch operation on the fingerprint area, a second fingerprint of the second touch operation is obtained; if the second fingerprint matches the reference fingerprint, the camera application is started and the captured picture is displayed. The operation can be accurately performed underwater to display the captured picture, thereby performing image processing more accurately.

[0101] In one embodiment, Figure 4As shown, the electronic device executes step S402 to enter the underwater mode; executes step S404 to start the underwater mode thread in the hardware abstraction layer; wherein the hardware abstraction layer (FP HAL) is the software part of the fingerprint recognition module, which is used to encapsulate the underlying functions of the fingerprint recognition module; executes step S406 to display the desktop interface at the second brightness, the desktop interface includes the fingerprint area, and the fingerprint area has no light spot; executes step S408 to obtain a second touch operation on the fingerprint area; executes step S410 to obtain a second fingerprint corresponding to the second touch operation; executes step S412 to detect whether there is a finger pressing on the fingerprint area; if it is determined that there is a finger pressing on the fingerprint area, executes step S414 to pass the finger pressing event to the camera application, and executes step S416 to open the camera application; Execute step S418 to display the camera button in the fingerprint area; when the finger presses the camera button, execute step S420 to obtain the first touch operation on the fingerprint area; execute step S422 to obtain the first fingerprint corresponding to the first touch operation; execute step S424 to detect whether there is a finger pressing on the fingerprint area; if it is determined that there is a finger pressing on the fingerprint area, execute step S426 to pass the finger pressing event to the camera application; execute step S428 to scale the shooting picture to achieve shooting; execute step S430 to exit the underwater mode; execute step S432, the hardware abstraction layer exits the picture collection polling. If the fingerprint area does not detect the finger pressing, report the finger not pressing event (none event) and continue to preview the shooting picture.

[0102] It is understandable that the above-mentioned image processing optimization solution can also be applied to voice systems, game systems and other non-sensing control scenarios, by setting the voice control similarity to control the target object, or by setting the touch to enhance the experience.

[0103] In one embodiment, an image processing method is also provided, which is applied to an electronic device, and the image processing method comprises the following steps:

[0104] Step A1: in the underwater mode, increase the preset first brightness to obtain a second brightness.

[0105] Step A2: displaying a desktop interface at a second brightness, where the desktop interface includes a fingerprint area.

[0106] Step A3: in response to a second touch operation on the fingerprint area, obtaining a second fingerprint of the second touch operation.

[0107] Step A4: If the second fingerprint matches the reference fingerprint, the camera application is started and the shooting picture is displayed.

[0108] Step A5: in response to the first touch operation, obtaining a first fingerprint continuously collected a target number of times during the first touch operation.

[0109] Step A6, improving the preset first fingerprint false recognition rate to obtain a second fingerprint false recognition rate; matching the first fingerprint with the reference fingerprint according to the second fingerprint false recognition rate.

[0110] Step A7: if the first fingerprint matches the reference fingerprint and the target number of polls is greater than the number threshold, determine the number of polls at which the target number of polls reaches the number threshold.

[0111] Step A8: if the polling number is an odd number, determine that the zoom event corresponding to the polling number is a zoom-out event; if the polling number is an even number, determine that the zoom event corresponding to the polling number is a zoom-in event.

[0112] Step A9: In response to the zoom event, zoom the captured image.

[0113] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
