Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
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 a mobile terminal according to the present invention is operable 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 2750.
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 shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The location information module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information, and a typical example of the location information module 115 is GPS. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.
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 base station 270 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.
Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.
Referring to fig. 3, a schematic diagram of a functional module of a mobile terminal according to a first embodiment of the present invention includes:
an obtaining module 301, configured to obtain a screenshot picture of a display interface according to an operation performed by a user if it is detected that the operation performed by the user is a preset color extraction trigger operation;
in the embodiment of the present invention, a user may trigger the mobile terminal to execute a corresponding function in an interactive manner with the mobile terminal, specifically, the user may operate the display interface of the mobile terminal through actions such as clicking, sliding, long pressing, and the like, and after detecting an operation executed by the user, the mobile terminal executes a function corresponding to the operation, for example, when the mobile terminal detects that the user clicks an icon of an application program on the display interface of the mobile terminal, the application program is started.
If the mobile terminal detects that the operation performed by the user is a preset color extraction triggering operation, the obtaining module 301 obtains a screenshot picture of the display interface according to the operation performed by the user.
An extracting module 302, configured to extract a target color from the screenshot picture;
in the embodiment of the present invention, the preset color extraction triggering operation may be a function of only triggering the obtaining module 301 to obtain the screenshot picture of the display interface and the extracting module 302 to extract the target color from the screenshot picture, for example, a virtual button for triggering color extraction may be set on the display interface, and a user may execute the color extraction triggering operation by clicking the virtual button, or an entity button for triggering color extraction may be set on the mobile terminal, and a user may execute the color extraction triggering operation by pressing the entity button in a preset manner.
Alternatively, the preset color extraction triggering operation may be an operation of additionally triggering a color extraction function on the basis of one or more functions already provided. For example, when the user performs an operation of closing an application, the general function is that the mobile terminal closes the application, and the operation of closing the application is further provided with a function of triggering color extraction, that is, the operation of closing the application is also a color extraction triggering operation.
The replacing module 303 is configured to, if the starting operation of the first application program is detected, replace the theme color of the first application program according to the target color when the first application program is started.
In this embodiment of the present invention, after the extracting module 302 extracts the target color, if the user clicks an icon of the first application on the display interface, that is, the user executes the starting operation of the first application, the mobile terminal starts the first application after detecting the starting operation of the first application, and in the starting process of the first application, the replacing module 303 replaces the target color with the theme color of the first application, so that the displayed theme color is the target color extracted by the extracting module 302 after the first application is started.
Optionally, after extracting the target color, the extracting module 302 may further cache the target color in the cache space, so that the replacing module 303 may read the target color from the cache space and implement the replacement of the theme color of the first application.
It should be noted that, in the embodiment of the present invention, after the extraction module 302 extracts the target color, if the mobile terminal detects that the operation performed by the user is the preset color extraction triggering operation, the operation returns to the acquisition module 301, the target module 301 acquires the screenshot picture, the extraction module 302 extracts the target color from the screenshot picture, and the target color extracted this time is replaced by the target color extracted last time.
In the embodiment of the present invention, when it is detected that the operation performed by the user is the preset color extraction triggering operation, the obtaining module 301 in the mobile terminal obtains the screenshot picture of the display interface according to the operation performed by the user, and the extracting module 302 extracts the target color from the screenshot picture, and if the starting operation of the first application is detected, the replacing module 303 replaces the theme color of the first application according to the target color when the first application is started, so that the theme color of the application changes when the application is started each time, thereby effectively adjusting the theme color and improving the user experience.
