Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

In the printing function of the electronic equipment, the printing parameters set by the user are less, so that the printing function of the electronic equipment is simpler, and the printing requirement of the user cannot be met. If the authority for configuring the printing parameters is provided for the user, the printing parameters can be configured incorrectly due to the complex setting of the printing parameters, so that the printing effect is poor, and even the printing is wrong.

Therefore, the image printing method determines the corresponding printing template according to the number of the images to be printed and the characteristics of the images to be printed, wherein the characteristics of the images to be printed comprise any one or more of the size, the content and the pixels of the images to be printed. And when a printing instruction is received, processing the picture to be printed according to the printing parameters corresponding to the printing template, sending the processed picture to be printed to a printer, and indicating the printer to print the processed picture to be printed. For selecting printing parameters, selecting a printing template can reduce the problems of printing failure and poor printing effect caused by parameter selection errors, and meanwhile, the printing template is determined according to the number and the characteristics of the pictures to be printed, so that the matching degree of the printing parameters corresponding to the printing template and the pictures to be printed is better, the pictures to be printed are printed after being processed according to the printing parameters corresponding to the printing template, and better printing effect can be obtained.

The following provides an exemplary description of a picture printing method provided in an embodiment of the present application.

The picture printing method provided by the embodiment of the application is applied to electronic equipment.

For example, the electronic device described in the embodiments of the present application may be a mobile phone, a wearable device (e.g., a smart watch, a smart bracelet, smart glasses, smart jewelry, etc.), a tablet computer, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and other electronic devices that can be connected to a printer. The electronic equipment comprises but is not limited to the iOS^®、Android^®、Microsoft^®A hong meng system (Harmony OS), or other operating system. The embodiment of the application does not set any limit to the specific type of the electronic device.

The picture printing method provided by the embodiment of the application can be suitable for various picture printing scenes. In the following, some application scenarios are described by taking an example that the electronic device is a mobile phone and combining with the accompanying drawings.

Scene one: big picture printing scene

Illustratively, as shown in fig. 1A, when the cell phone detects an operation of opening a gallery application, a gallery preview interface shown in fig. 1B is displayed, and the gallery preview interface shows pictures stored in the cell phone. And marking the selected picture if the operation of selecting the picture (such as the operation of long-time pressing the picture) is detected on the gallery preview interface. For example, as shown in fig. 1C, a mark of "√" is added to the selected picture. After the picture is selected, the picture operation option is displayed on the picture library preview interface, and the picture can be correspondingly processed by clicking the picture operation option. For example, as shown in fig. 1C, the picture manipulation options include "share", "select all", "copy", "more" options. And if the operation of clicking the sharing is detected, the sharing interface is opened by the mobile phone. As shown in fig. 1D, the sharing interface displays the selected picture and displays sharing options such as "information", "email", "bluetooth", "print", and the like, and the user can open another process by clicking any sharing option to send or print the selected picture. And when the mobile phone detects the operation of clicking 'printing', opening a printing process and taking the selected picture as the picture to be printed. Exemplarily, the picture to be printed is one, the mobile phone determines that the picture to be printed conforms to the large-picture printing template according to the size and the resolution of the picture to be printed, displays a large-picture printing interface as shown in fig. 1E, and displays the picture to be printed on the large-picture printing interface.

In one embodiment, the mobile phone determines the number of pictures to be printed which need to be cut according to the scaling and the size of paper, and displays the pictures on a large picture printing interface. For example, as shown in fig. 1E, a dividing line is displayed on the picture to be printed, and the dividing line divides the picture to be printed into 4 sub-pictures.

And on the large image printing interface, if the operation of clicking to start printing is detected, the mobile phone processes the image to be printed according to the printing parameters corresponding to the large image printing template to obtain 4 sub images, and instructs the printer to print the 4 sub images in sequence. The processing of the picture to be printed comprises zooming, cutting, filling and other processing. And after the user obtains the printed 4 sub-images, splicing the 4 sub-images to obtain a complete large image.

In an embodiment, the large image printing interface displays a part of printing parameters corresponding to the large image printing template, for example, the printing parameters displayed by the large image printing interface include: the identification of the currently connected printer "HP Laser M330", and the mode "a 4 paper/black and white/1 copy/machine direction", and the scaling "magnification by 2". In the pattern, a4 paper indicates the paper size, black and white indicates the color, 1 copy indicates the number of prints, and the vertical direction indicates the arrangement direction. In one embodiment, the user may modify a portion of the printing parameters corresponding to the large image printing template, for example, in the large image printing interface, the mobile phone enters a printer page in response to the user clicking "printer selection" operation, so that the user may select a printer. Or the mobile phone responds to the operation of clicking the mode, enters a mode page, and modifies the paper size, the color, the printing quantity and the arrangement direction according to the modification operation of the user. Or, the mobile phone responds to the operation of clicking the zoom scale triggered by the user, enters a zoom scale page and resets the zoom scale. Illustratively, if an operation of clicking "zoom scale" is detected, the mobile phone displays a zoom scale setting page as shown in fig. 1F. In the zoom setting page, the user may select a zoom option to reset the zoom. For example, the currently selected zoom ratio is "zoom in 2 times", and if the user clicks "zoom in 1 time" operation is detected, the zoom ratio is modified to zoom in 1 time. And if the operation of clicking the 'cancel' option is detected, returning the mobile phone to the large image printing interface. If the operation of modifying the printing parameters by the user is received, when the operation of clicking 'start printing' is detected, the mobile phone processes the picture to be printed according to the modified printing parameters.

Optionally, when detecting that the user modifies the printing parameter, the mobile phone may further prompt the user whether to save the large image printing template after the printing parameter is modified. And under the condition that the user is detected to indicate to save the large image printing template after the printing parameters are modified, the mobile phone saves the large image printing template after the printing parameters are modified. And under the condition that the user indicates not to store the large image printing template after the printing parameters are modified, the mobile phone does not store the large image printing template after the printing parameters are modified. The subsequent user can select one of the large image printing template with the modified printing parameters and the large image printing template without the modified printing parameters as a default large image printing template.

In one embodiment, the positions of the subgraphs printed by the printer can be identified so as to facilitate splicing by a user. For example, the row number and column number where the sub-graph resides, or the page number where the sub-graph resides, etc. may be identified.

As shown in fig. 2A, in an embodiment, the large graph printing interface further displays an option of "splicing identifier", and the mobile phone is configured to mark the sub-graph according to a parameter of the splicing identifier, and instruct the printer to print the marked sub-graph. The user can view the parameters of the splicing identification and edit the parameters of the splicing identification. For example, if it is detected that the user clicks the option of "splice mark", an interface of the splice mark as shown in fig. 2B is opened. And displaying various formats of the splicing marks on a splicing mark interface. For example, the format of the splice identification includes a default format and a custom format. The default format has parameters of blank 2 rows and 2 columns, here p rows and q columns. The margin represents a blank area left around the divided subgraph. Here, p rows and q columns represent the concatenation identification marked on the subgraph. The parameters corresponding to the custom format can be input by the user. For example, the names of the custom formats added by the user are schema 1, schema 2, and custom 1, respectively. The format parameter of the mode 1 is margin 2 rows and 2 columns, which are connected with p rows and q columns; the parameter of the format of the mode 2 is blank 0 row and 0 column, none; parameters of the format of the custom 1 are blank 1 row and 1 column, and p rows and q columns. Meanwhile, the mobile phone displays the sub-image style added with the splicing identification on a splicing identification interface according to the currently selected splicing identification format, and a user can sequentially browse the printing effect corresponding to each divided sub-image by clicking a preview button. For example, the currently selected concatenation identification is the default, the currently previewed sub-graph is the sub-graph located in 2 rows and 2 columns, and "2 rows and 2 columns here" is displayed at the peripheral edge of the sub-graph.

Scene two: long-chart printing scene

Illustratively, as shown in fig. 3A and 3B, in the gallery preview interface, if an operation of selecting a picture is detected, a mark of "√" is added to the selected picture. Upon selection of the picture, the gallery preview interface displays picture manipulation options, for example, as shown in FIG. 3B, the picture manipulation options include "share", "select all", "copy", "more" options. If the operation of clicking the sharing is detected, the mobile phone displays a sharing interface as shown in fig. 3C. The sharing interface displays the selected pictures and displays sharing options such as 'information', 'e-mail', 'Bluetooth', 'printing', and the like. If the operation of clicking printing is detected, the mobile phone starts a printing process, and the selected picture is taken as the picture to be printed. Exemplarily, the picture to be printed is one, the mobile phone determines that the picture to be printed conforms to the long-image printing template according to the size and the resolution of the picture to be printed, displays a long-image printing interface as shown in fig. 3D, and displays the picture to be printed on the long-image printing interface. The long-image printing interface also displays part of printing parameters corresponding to the long-image printing template, for example, the printing parameters displayed on the long-image printing interface include: the identification of the currently connected printer "HP Laser M330", mode "a 4 paper/color/1 copy/machine direction", and scaling "magnification 1 time". Meanwhile, the mobile phone determines that the picture to be printed needs to be divided into 2 sub-pictures according to the size of the picture to be printed and the size of paper used for printing, a dividing line is displayed on the picture to be printed, and the picture to be printed is divided into 2 sub-pictures by the dividing line.

And if the operation of clicking to start printing is detected, the mobile phone processes the picture to be printed according to the printing parameters corresponding to the long picture printing template to obtain 2 sub-pictures, and instructs the printer to print the 2 sub-pictures in sequence. And after the user obtains the printed 2 sub-images, splicing the 2 sub-images to obtain a complete long image. In an embodiment, a user can modify a printing parameter corresponding to the long-image printing template on the long-image printing interface, and if an operation of modifying the printing parameter is detected, the subsequent mobile phone processes the image to be printed according to the modified printing parameter. In an embodiment, the mobile phone adds the splicing identifier to each sub-image according to the preset splicing identifier, for example, the splicing identifier may be a page number, the mobile phone instructs the printer to print the sub-image to which the page number is added, and the user may determine the position of each sub-image according to the page number, thereby facilitating splicing.

Scene three: print scenes for photo taking

Illustratively, as shown in fig. 4A and 4B, in the gallery preview interface, if an operation of selecting a picture is detected, a mark of "√" is added to the selected picture. After the picture is selected, the picture library preview interface displays the picture operation options of sharing, full selecting, copying and more. If the operation of clicking the sharing is detected, the mobile phone displays a sharing interface shown in fig. 4C. The sharing interface displays the selected pictures and displays sharing options such as 'information', 'e-mail', 'Bluetooth', 'printing', and the like. And if the operation of clicking printing is detected, the mobile phone opens a printing process and takes the selected picture as the picture to be printed. Exemplarily, the picture to be printed is one, the mobile phone determines that the picture to be printed conforms to the photo printing template according to the size and content of the picture to be printed, displays a photo printing interface as shown in fig. 4D, and displays the photo to be printed on the photo printing interface. In an embodiment, the mobile phone determines the number of the pictures to be printed which can be arranged on the paper according to the size of the pictures to be printed and the size of the paper, and displays the arrangement effect of the pictures to be printed on the paper on the photo printing interface. And the photo printing interface also displays part of printing parameters corresponding to the photo printing template. For example, the identification "HP Laser M330" of the currently connected printer, the mode "photo paper/color/4 × 6/portrait", and the scaling "magnification 1" are displayed. And if the operation of clicking to start printing is detected, the mobile phone processes the picture to be printed according to the printing parameters corresponding to the photo printing template and instructs the printer to print the processed picture to be printed. In an embodiment, a user can modify the printing parameters corresponding to the photo printing template on the photo printing interface, and if the operation of modifying the printing parameters is detected, the subsequent mobile phone processes the picture to be printed according to the modified printing parameters.

Scene four: landscape picture printing scene

The electronic device 100 may implement a shooting function through the ISP, the camera 193, the video codec, the GPU, the display 194, the application processor, and the like.

The ISP is used to process the data fed back by the camera 193. For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The storage data area may store data (such as audio data, phone book, etc.) created during use of the electronic device 100, and the like. In addition, the internal memory 121 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), and the like. The processor 110 executes various functional applications of the electronic device 100 and data processing by executing instructions stored in the internal memory 121 and/or instructions stored in a memory provided in the processor.

The electronic device 100 may implement audio functions via the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone interface 170D, and the application processor. Such as music playing, recording, etc.

The audio module 170 is used to convert digital audio information into an analog audio signal output and also to convert an analog audio input into a digital audio signal. The audio module 170 may also be used to encode and decode audio signals. In some embodiments, the audio module 170 may be disposed in the processor 110, or some functional modules of the audio module 170 may be disposed in the processor 110.

The pressure sensor 180A is used for sensing a pressure signal, and converting the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A can be of a wide variety, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message. And when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

The touch sensor 180K is also called a "touch device". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on a surface of the electronic device 100, different from the position of the display screen 194.
