Description

CABC-based power consumption control method and mobile terminal

Technical Field

The invention relates to the technical field of power consumption control of terminals, in particular to a power consumption control method based on content adaptive backlight control CABC and a mobile terminal.

Background

As the average duration of using the mobile terminal increases, the cruising performance of the mobile terminal is more and more concerned by the user, and becomes an important factor influencing the user experience. Therefore, a power consumption management and control strategy is designed to become a solution for improving the endurance of the mobile terminal on a software level.

The display screen is always a power-consuming user in the mobile equipment, and the backlight of the display screen is a battery killer. At present, content-adaptive backlight control based CABC is a relatively mature backlight power saving technology for mobile terminals. The meaning of CABC is: content Adaptive Brightness Control-CABC. Wherein C means content, and a content analyzer circuit is added to the drive IC.

As shown in fig. 1, it is assumed that when the mobile terminal processor transmits a picture data to the driver IC, the picture 155 should be displayed under the backlight 165 with 100% backlight brightness, at this time, the data of the picture can be calculated and counted by using the CABC technique, and then the gray-scale brightness of the picture is automatically increased by 30% according to the setting and the algorithm, and the picture is brightened, as shown in the picture 156, at this time, the backlight brightness is further decreased by 30%, that is, the picture is never darkened by using the backlight 166 with 70% backlight brightness. Since we have previously passed the picture through the analyzer circuit to compensate for the brightness, the user can get a display effect comparable to the original circuit, as shown by picture 157, but with a 30% reduction in backlight power consumption.

CABC achieves power savings by increasing the content gray scale level while reducing the backlight brightness. Generally, there are four main modes of CABC, each corresponding to a different CABC value:

(1) closing the off mode OffMode, closing all CABC functions, wherein the corresponding CABC value is 23;

(2) an interface Image Mode UI Image Mode optimizes the power consumption when the UI picture is displayed, the picture quality is ensured as much as possible, 10% of power consumption can be saved, and the corresponding CABC value is 24;

(3) the Still picture Mode Still Image Mode optimizes the power consumption when the Still picture is displayed, the picture quality loss in the Mode is within an acceptable range, 30% of power consumption can be saved, and the corresponding CABC value is 25;

(4) the Moving Image Mode optimizes the power consumption when displaying a Moving picture, and in this Mode, the power consumption is reduced to the maximum extent, but the loss of picture quality is caused, and the power consumption can be saved by 30% + and the corresponding CABC value is 26.

The values of the four modes can be regarded as the CABC regulation strength, the higher the CABC value is, namely the higher the regulation strength is, the more obvious the power consumption saving effect is.

However, the four modes do not switch well.

Fig. 2 illustrates the mobile terminal 100 having various components, but it is to be understood that not all illustrated components are required to be implemented. 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 may generally include 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 broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting system such as a data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 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 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth (TM), Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee (TM), and the like.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module 115 is a GPS (global positioning system). According to the current technology, the GPS calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal 100. The microphone 122 may receive sounds (audio data) via the microphone 122 in a phone call mode, a recording mode, a voice recognition mode, or the like, and is capable of processing such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 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 130 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 changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 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 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 141.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100.

The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 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 a signal for identifying whether the mobile terminal 100 is accurately mounted on the cradle. The output unit 150 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 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 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 151 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 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 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 touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 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 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

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 the memory 160 and executed by the controller 180.

In this embodiment, the brightness variation value is an absolute value of a difference between a brightness average value of the display interface before switching and a brightness average value of the display interface after switching. The average brightness value may be obtained by dividing the sum of the brightness of all the pixels of the display interface by the sum of the number of all the pixels.

a second determining module 46 configured to determine the value of CABC according to the threshold range.

According to the CABC-based power consumption control method and the mobile terminal, the CABC value is adjusted according to different applications, and the content gray scale can be increased to the maximum extent and the backlight brightness can be reduced on the premise that the application function is not influenced, so that the effect of reducing the power consumption is achieved. For example, when a user uses video software, because interface switching basically does not exist in video playing and the screen brightness is kept constant, CABC can be increased as much as possible in the scene, the backlight brightness is reduced, and the gray scale is used for supplementing, so that the watching effect is not influenced, the power consumption can be effectively saved, and the cruising ability of the mobile phone is improved.

The invention can intelligently adjust CABC value according to different interface content brightness distribution of each application. Specifically, for a certain application, when each time an interface switch, namely, resume activity, is executed, the content brightness distribution of the interface is recorded, and if the content brightness change between the two switches is strong, it proves that the application has strong dependency on the screen display effect (for example, gallery-like application), the CABC value can be adjusted down so as not to affect the display effect. If the content brightness change between two switches is weak, the CABC value can be properly adjusted up to save power consumption. The invention records the interface switching of the application program used by the user, the intensity of the screen brightness change is an average value obtained by multiple switching records, and the screen brightness change tends to be more real level along with the longer time used by the user. The average value is compared with a preset threshold value, and the CABC value of the corresponding gear is set according to which gear the value is positioned.
