Mobile terminal and picture processing method

Technical Field

The invention relates to the technical field of image processing, in particular to a mobile terminal and a picture processing method.

Background

With continuous progress and rapid development of mobile communication technology, many intelligent terminals such as mobile phones and tablet computers have a photographing function, for example, after a user takes a photo by using the intelligent terminal, the taken photo can be modified by image processing software to change the image attributes such as contrast, saturation and color of the photo, so that the taken photo is more beautiful. Among them, the picture splicing function in the mobile terminal is also more and more widely used. The picture splicing is to seamlessly splice two or more partially overlapped images to generate a high-resolution image with a wide view angle; the basic shooting principle is to search the edge parts of two pictures and superpose the areas with the closest imaging effect to generate a picture with a larger visual angle.

In the existing picture splicing method, after a user presses a photographing key, the mobile terminal detects the overlapping area of every two pictures in real time along with the change of the rotation angle of the mobile terminal, and then splices the photographed pictures in real time.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

in the existing picture splicing method, the mobile terminal splices the shot pictures in real time, that is, the mobile terminal needs to calculate the overlapping area of every two pictures in real time, so that the processing power consumption of the mobile terminal is increased; and when all the shot pictures have unclear pictures, the display effect after the pictures are spliced is also influenced.

More or fewer components may alternatively be implemented. The elements of the mobile terminal 100 will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit 110 may include: at least one of a mobile communication module 111, a wireless internet module 112, and a short-range communication module 113.

The mobile communication module 111 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 112 supports wireless internet access of the mobile terminal 100. The wireless internet module 112 may be internally or externally coupled to the terminal. The wireless internet access technology referred to by the wireless internet module 112 may include Wireless Local Area Network (WLAN), wireless compatibility authentication (Wi-Fi), wireless broadband (Wibro), worldwide interoperability for microwave access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like.

The user input unit 120 may generate key input data to control various operations of the mobile terminal 100 according to a command input by a user. The user input unit 120 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects a change in resistance, pressure, capacitance, etc. due to being touched), a jog wheel, a jog stick, etc. In particular, when the touch pad is superimposed on the display unit 141 in the form of a layer, a touch screen may be formed.

The sensing unit 130 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 130 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 130 can detect whether the power supply unit 180 supplies power or whether the interface unit 160 is coupled with an external device.

The interface unit 160 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port (a typical example is a Universal Serial Bus (USB) port), a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 160 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal 100. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal 100 is accurately mounted on the cradle.

The output unit 140 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 140 may include a display unit 141, an audio output module 142, and the like.

The display unit 141 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 141 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 141 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, or the like.

Meanwhile, when the display unit 141 and the touch pad are stacked on each other in the form of layers to form a touch screen, the display unit 141 may function as an input device and an output device. The display unit 141 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, mobile terminal 100 may include two or more display units (or other display devices), for example, mobile terminal 100 may include an external display unit (not shown) and an internal display unit (not shown).

The audio output module 142 may include a speaker, a buzzer, and the like.

The memory 150 may store software programs or the like for processing and controlling operations performed by the controller 170, or may temporarily store data (e.g., a phonebook, messages, still images, videos, etc.) that has been output or is to be output. Also, the memory 150 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

In addition, the controller 170 may include a multimedia module 171 for reproducing or playing back multimedia data, and the multimedia module 171 may be constructed within the controller 170 or may be constructed separately from the controller 170. The controller 170 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 180 receives external power or internal power and provides appropriate power required to operate the respective elements and components under the control of the controller 170.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 170. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in memory 150 and executed by controller 170.

Up to this point, the mobile terminal 100 has been described in terms of its functions. Hereinafter, the slide-type mobile terminal 100 among various types of mobile terminals 100, such as the folder-type, bar-type, swing-type, slide-type mobile terminal 100, etc., will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal 100, and is not limited to the slide type mobile terminal 100.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which the mobile terminal 100 according to the present invention is capable of operating will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular BS270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

The mobile communication module 112 of the wireless communication unit 110 in the mobile terminal accesses the mobile communication network based on the necessary data (including the user identification information and the authentication information) of the mobile communication network (such as the mobile communication network of 2G/3G/4G, etc.) built in the mobile terminal, so as to transmit the mobile communication data (including the uplink mobile communication data and the downlink mobile communication data) for the services of web browsing, network multimedia playing, etc. of the mobile terminal user.

The wireless internet module 113 of the wireless communication unit 110 implements a function of a wireless hotspot by operating a related protocol function of the wireless hotspot, the wireless hotspot supports access by a plurality of mobile terminals (any mobile terminal other than the mobile terminal), transmits mobile communication data (including uplink mobile communication data and downlink mobile communication data) for mobile terminal user's services such as web browsing, network multimedia playing, etc. by multiplexing the mobile communication connection between the mobile communication module 112 and the mobile communication network, since the mobile terminal essentially multiplexes the mobile communication connection between the mobile terminal and the communication network for transmitting mobile communication data, the traffic of mobile communication data consumed by the mobile terminal is charged to the communication tariff of the mobile terminal by a charging entity on the side of the communication network, thereby consuming the data traffic of the mobile communication data included in the communication tariff contracted for use by the mobile terminal.

Specifically, when the number of the pre-saved pictures is not less than N, the mobile terminal may divide N pictures in the pre-saved pictures into a group; when the number of the pre-saved pictures is less than N, the mobile terminal may divide all remaining pictures in the pre-saved pictures into one group. For example, if 10 pictures are stored in advance, when N is 3, M is 4. Namely: dividing 1 st to 3 rd pictures into a first group; dividing 4 th to 6 th pictures into a second group; dividing the 7 th to 9 th pictures into a third group; divide the 10 th page into a fourth group.

And step 501b, when at least one picture with the definition larger than a preset threshold exists in each group of pictures, selecting one picture in each group of pictures as a picture to be spliced.

In a specific embodiment of the present invention, when at least one picture with a definition greater than a preset threshold exists in each group of pictures, the mobile terminal may select one picture in each group of pictures as a picture to be stitched. Preferably, when more than one picture with the definition greater than the preset threshold exists in each group of pictures, the mobile terminal may select the picture with the highest definition as the picture to be spliced.

And 502, splicing the M pictures to be spliced into a panoramic picture when the M pictures to be spliced all meet the preset splicing condition.

In the specific embodiment of the invention, when the M to-be-spliced pictures all meet the preset splicing condition, the mobile terminal can splice the M to-be-spliced pictures into one panoramic picture. Wherein, the preset splicing condition can be as follows: and each picture to be spliced and at least one picture to be spliced in the M pictures to be spliced have an overlapped area.

Preferably, in the embodiment of the present invention, the mobile terminal may be preset with a splicing mode; when the splicing mode is in an open state, the mobile terminal can splice the pictures to be spliced into a panoramic picture; and when the splicing mode is in a closed state, the mobile terminal cannot splice the pictures to be spliced into one panoramic picture. Therefore, the mobile terminal can firstly judge whether the preset splicing mode is in an open state, and when the splicing mode is in the open state, the mobile terminal can select M pictures with the definition greater than a preset threshold value from the pre-stored pictures as the pictures to be spliced.

According to the picture processing method provided by the embodiment of the invention, the mobile terminal can select M pictures with the definition greater than the preset threshold value from the pre-stored pictures for splicing, instead of splicing all the shot pictures in real time in the prior art. Therefore, compared with the prior art, the mobile terminal and the picture processing method provided by the embodiment of the invention not only can reduce the processing power consumption of the mobile terminal, but also can improve the display effect after picture splicing; moreover, the method is simple and convenient to realize, convenient to popularize and wide in application range.
