Referring to fig. 1, a schematic flow chart of a screen capturing method for an intelligent terminal 20 according to a preferred embodiment of the present invention is shown, where the screen capturing method includes the following steps:
s101: it is determined whether the fingerprint sensor 25 provided at the rear surface of the smart terminal 20 detects an external fingerprint.
The intelligent terminal 20 may be a terminal device with a fingerprint detection function, such as a smart phone, a tablet computer, and a multimedia player. The fingerprint sensor 25 is disposed on the back of the intelligent terminal 20, and is capable of receiving external fingerprint information and converting the fingerprint information into digital signals, and then transmitting the digital signals to other modules in the intelligent terminal 20 for subsequent processing. In this step, the fingerprint sensor 25 receives a finger touch operation, that is, the user presses a finger on the fingerprint sensor 25, and the fingerprint sensor 25 collects the finger fingerprint of the user as an external fingerprint. The criterion for determining whether the external fingerprint is detected by the fingerprint sensor 25 may be determining the integrity of the external fingerprint, and if the external fingerprint is incomplete or fuzzy, determining that the external fingerprint is not detected. And comparing and matching the preset reference fingerprint with the external fingerprint in a preset reference fingerprint mode, and if the matching is successful, determining that the external fingerprint is detected.
S102: when the fingerprint sensor 25 detects an external fingerprint, it is determined whether at least one key disposed on a side surface of the smart terminal 20 receives a pressing operation.
When step S101 is determined to be true, i.e., the fingerprint sensor 25 detects an external fingerprint, this step is performed. The keys may be keys such as a volume up key 21, a volume down key 22, and a power key 23, which are disposed on the side of the intelligent terminal 20, and may be disposed on the right side or the left side of the intelligent terminal 20. Such an arrangement takes into account the one-handed operation of the user, for example, when the user holds the smart terminal 20 with one hand in the right hand, the thumb can press the key provided on the right side, and the index finger, middle finger, or ring finger can contact or press the fingerprint sensor 25 provided on the back side of the smart terminal 20, thereby achieving the one-handed operation. When the user uses the left hand, the user can press the key arranged on the left side surface. When each key is pressed, the state of the circuit changes, and the circuit is identified by the detection circuit and converted into a digital signal to be reported to the intelligent terminal 20. In the step, one key or a combination of several keys can be used as a target for judging the pressing operation; when more than two key combinations are selected, the keys involved in the pressing operation must be kept at a short distance, for example, a combination of a volume up key and a volume down key.
S103: when at least one key arranged on the side surface of the intelligent terminal 20 receives a pressing operation, the display interface of the screen of the intelligent terminal 20 is stored as a picture.
When the step S102 is determined to be satisfied, that is, when at least one key disposed on the side surface of the intelligent terminal 20 receives a pressing operation, the step is executed. The step executes the screen capture operation, and the execution condition of the step is that the fingerprint sensor 25 detects an external fingerprint, and a key arranged on the side surface of the intelligent terminal 20 is pressed. The screen display of the intelligent terminal 20 is realized by displaying pixel points, and the display interface is composed of the display contents of different pixel points. When the intelligent terminal 20 displays, the information to be displayed includes information of each pixel point on the screen, so that the information to be displayed only needs to be stored as one picture when the step is executed.
Obviously, if the fingerprint sensor 25 does not detect an external fingerprint, pressing the key will not trigger a screen capture operation, but will execute the operation function set by the key itself, thereby implementing the multiple functions of the key to be distinguished according to the fingerprint detection.
Referring to fig. 2, which is a schematic flow chart of a screen capturing method for an intelligent terminal according to another preferred embodiment of the present invention, before step S101', the screen capturing method further includes the following steps:
s100: at least one reference fingerprint is preset in the intelligent terminal 20.
The reference fingerprint is a fingerprint sample collected by a user or other users in advance, and the matching condition of the external fingerprint is judged by taking the reference fingerprint sample as a reference in the subsequent steps. When the reference fingerprint is preset, a prompt interface can be displayed on the screen of the intelligent terminal 20 to prompt a user to place a finger to be collected on the fingerprint sensor 25, the fingerprint sensor 25 identifies the fingerprint information of the finger and converts the fingerprint information into image information, the image information is recorded in the intelligent terminal 20, and after the fingerprint information is collected successfully, the prompt on the screen is used for prompting that the reference fingerprint collection is finished. A plurality of reference fingerprints can be preset in the intelligent terminal 20, so that subsequent operation can be performed by different fingers conveniently, and operation can be performed by different operators conveniently.
Correspondingly, when the step S101' is executed, after the external fingerprint is detected by the fingerprint sensor 25, the intelligent terminal 20 matches the external fingerprint with the reference fingerprint, and after the matching is successful, the external fingerprint can be determined to be detected.
Referring to fig. 3, a detailed flowchart of step S101 'in fig. 2 is shown, where step S101' includes:
s101' -1: the fingerprint sensor 25 collects the external fingerprint at a preset frequency.
Since it is unknown when the user places a finger on the fingerprint sensor 25 for fingerprint recognition, the fingerprint sensor 25 collects the external fingerprint at a predetermined frequency in order to ensure that the user's operation can be recognized in time. The fingerprint sensor 25 needs a certain time for sampling and identifying fingerprint information once, and the fingerprint information detected by the fingerprint sensor 25 needs to be recorded in each working period in milliseconds, so that whether complete fingerprint information or incomplete fingerprint information is detected or even no fingerprint information exists, the fingerprint information is detected and sampled to form fingerprint image information. Therefore, the fingerprint sensor 25 needs to perform a cycle work according to the preset frequency, and the fingerprint sensor 25 may be continuously called to perform a fingerprint detection operation through a timing task in the intelligent terminal 20, where a reciprocal of a period of the timing task is the preset frequency.
S101' -2: and judging whether the external fingerprint is matched with the reference fingerprint through a fingerprint matching algorithm.
The fingerprint matching algorithm is a relatively mature prior art and is implemented based on image identification, specifically, image features including geometric line features, gray scale and the like are compared by extracting image information of the external fingerprint and image information of the reference fingerprint, so as to obtain a matching result. In the computer program, the image information is represented by the numerical value of each pixel point in the image, so that the image characteristics can be compared through the comparison operation of the numerical values of the pixel points. The same person can be influenced by factors such as weather, seasons, external wear and the like under different states, so that fingerprints can have slight difference, therefore, fingerprint matching does not mean that the external fingerprints are the same as the reference fingerprints, but the matching degree of the external fingerprints and the reference fingerprints reaches a certain proportion, namely the external fingerprints and the reference fingerprints are considered to be successfully matched, and the matching degree of the external fingerprints and the reference fingerprints can be considered to be matched as the same fingerprint when reaching more than 90%. In the step S101' -1, once the fingerprint sensor 25 collects fingerprint information, the matching determination between the external fingerprint and the reference fingerprint is performed once, so as to identify the finger placement operation of the user in time.
This embodiment has used fingerprint identification as the judgement condition whether to carry out the screen capture operation, for the key combination mode among the prior art, has user identification's effect, has promoted security and operation convenience, has avoided the maloperation that key combination mode caused.
As a further improvement of the above screen capture method, the step S101' -1 is performed at least 5 times per second. The step S101' -1 is performed to ensure that an external fingerprint is found to be in contact with the fingerprint sensor 25 for the first time, so the selection of the preset frequency is very important. If the preset frequency is higher, the gap between the two detection processes can be shortened, the sensitivity is higher, and the contact between the external fingerprint and the fingerprint sensor 25 can be found more timely; however, the higher operating frequency also brings a larger operation load to the intelligent terminal 20, and occupies more system resources. Similarly, if the preset frequency is too low, the contact between the external fingerprint and the fingerprint sensor 25 cannot be found in time, and the subsequent matching identification step is delayed, so that the response to the user operation is slow. In combination with the above factors, the preset frequency is preferably at least 5 times per second in this embodiment, and at such an operating frequency, the fingerprint sensor 25 can detect the external fingerprint without omission and will not occupy too much system resources.
As a further improvement of the screen capture method, when the step S102 is executed, the key is the power key 23. In this embodiment, the key for triggering the screen capturing operation is preferably selected, and the number of the keys is only one, namely, the power key 23. The power key 23 is a key used for turning on and turning off the intelligent terminal 20, and is arranged on a side surface of the intelligent terminal 20. According to the arrangement of the embodiment, taking the power key 23 arranged on the right side as an example, when a user wants to capture a screen, the user only needs to hold the smart terminal 20 with the right hand, place the forefinger on the fingerprint sensor 25 on the back of the smart terminal 20, place the thumb on the power key 23 and perform pressing operation, and then the screen capture operation can be completed without two-hand operation and without touching the function of the power key 23.
