Title of Invention: METHOD AND APPARATUS FOR

REDUCING INTERFERENCE AND MOBILE TERMINAL

Technical Field

[0001] The present invention relates to the field of mobile equipment, and in particular to a method and apparatus for reducing interference and mobile terminal. This application claims priority from Chinese patent application No. 201310047860.6, filed February 6, 2013 and U.S. patent application Serial No. 14/108,985, filed December 17, 2013, the entire disclosures of which hereby are incorporated by reference.

display resolution and color configuration are provided for better user experiences. To achieve such an object, a mobile industry processor interface (MIPI) is provided.

[0003] MIPI is an alliance set up by ARM, Nokia, ST, and TI, etc., with the object to

standardize interfaces within a mobile terminal, such as a camera, a display screen interface, and a radio frequency/baseband interface, so as to lower the complexity of design of a mobile phone and increase flexibility of the design. At present, there are a series of intra-mobile phone interface standards, such as camera interface CSI, display screen interface DSI, radio frequency interface DigRF, and microphone/speaker interface SLIMbus, etc. Therefore, manufacturers of mobile terminals may flexibly select different chips and modules as demanded, and it is more quick and convenient for modifying designs and functions.

Summary

[0004] It was found by the inventors that MIPI display interface DSI includes 4 data lines and 1 clock line, and the harmonic components produced by signals transmitted at a high speed may fall into the band ranges of radio communication (such as a radio frequency (RF) receiver), which brings interference to the radio communication, and hence the performance of the radio communication is greatly lowered.

[0005] In the prior art, hardware methods are generally used to alleviate interference, such adding a common choke or a low-pass filer, etc., or adding a copper sheet or a ferrite absorber, etc. These methods bring few effects to those bands lower than 1 GHZ although they alleviate interference to a certain degree. Furthermore, these methods increase the cost, need certain space (e.g., take up space), and often conflict with the mechanical designs of mobile terminals.

Description of Embodiments

[0027] The interchangeable terms "electronic apparatus" and "electronic device" include portable radio communication apparatus. The term "portable radio communication apparatus", which hereinafter is referred to as a "mobile terminal", "portable electronic device", or "portable communication device", comprises all apparatuses such as mobile telephones, pagers, communicators, electronic organizers, personal digital assistants (PDAs), smart phones, portable communication devices or the like.

[0028] In the present application, embodiments of the invention are described primarily in the context of a portable electronic device in the form of a mobile telephone (also referred to as "mobile phone"). However, it shall be appreciated that the invention is not limited to the context of a mobile telephone and may relate to any type of appropriate electronic apparatus having the function of photographing and sound recording.

[0029] Embodiment 1

[0030] An embodiment of the present invention provides a method for reducing interference.

Fig. 1 is a flowchart of the method of an embodiment of the present invention. As shown in Fig. 1, the method includes:

[0031] Step 101: selecting a display mode of a pixel, for a frequency falling into a receiving band range of radio communication, according to a corresponding relation between the pixel to be displayed and a strength value of interference induced in the frequency.

[0032] In this embodiment, a pixel to be displayed in a different display mode may produce a different interference. And for a frequency falling into a receiving band range of radio communication, a strength value of interference induced in the frequency may be reduced by modifying the display mode of the pixel.

[0033] Fig. 2 is another flowchart of the method of an embodiment of the present invention.

As shown in Fig. 2, the method includes:

[0034] Step 201 : determining a clock of transmission in an MIPI display interface according to a band range of radio communication, so as to avoid a harmonic frequency induced by the MIPI transmission from falling into a receiving band range of radio communication; and

[0035] Step 202: selecting a display mode of a pixel for a frequency falling into the

receiving band range of radio communication, according to a corresponding relation between the pixel to be displayed and a strength value of interference induced in the frequency.

[0036] In this embodiment, the MIPI clock may be allocated according to the band range of radio communication in a mobile terminal. First, the band range of radio communication of the mobile terminal may be determined, and in particular, the band range may be determined according to the parameters of the operator. For example, the band range may be DCS 1800, and PCS 1900, etc.; and then the MIPI clock may be allocated, so as to avoid harmonic frequencies induced by the MIPI display from falling into the band range of radio communication.

[0037] Fig. 3 shows a schematic diagram of an RX frequency range of a radio receiver. As shown in Fig. 3, the radio communication may include a plurality of bands. The MIPI clock may be allocated according to band ranges of radio communication in the mobile terminal, so that the harmonic frequencies induced by the MIPI DSI transmission do not fall into these band ranges.

[0038] In this embodiment, the frequency allocation in step 201 may solve the problem of low-frequency interference in most scenarios; however, interference still exists in certain scenarios, such as for GSM850, EGSM900, and 3GPP Band 20, etc.

[0039] Fig. 4 is a schematic diagram showing that interference still exists in Band 20 at

802.5 MHZ. As shown in Fig. 4, it is failed at 802.5 MHZ. It should be noted that for the sake of simplicity, only some of the cases are shown.

[0040] In this embodiment, for the frequencies falling into the band ranges of radio communication, the display modes of the pixels may be selected according to the strength value of interference induced by display of the pixels at the frequencies. The relation between the pixels to be displayed and the strength value of interference induced in the frequencies may be predetermined, and may also be determined dynamically. The prior art may be referred to for how to determine the corresponding relation between the display of the pixels and the strength value of the interference induced in the frequencies.

[0041] In this embodiment, the display mode may be red, green and blue (RGB) mode, and the display modes are different as RGB values are different. The RGB values may be ranged from 0 to 255. For example, the RGB of a certain pixel may be (0, 255, 209). The prior art may be referred to for details of RGB. However, the present invention is not limited thereto, and other display modes may also be used, such as a CMYK mode, an LAB mode, and an HSB mode, etc. Following description is given taking only an RGB mode as an example.

[0042] Different display modes of pixels may produce different harmonics, thereby possibly bringing different interference to the radio communication. For example, if a needed display mode (0, 255, 255) is used for a pixel, it is possible that relatively large interference is induced in the frequency falling into the band range of the radio communication; while in another display mode (0, 255, 244), relatively small interference may be induced. Therefore, for some pixels, they may be displayed by using different display modes, thereby reducing interference to the radio communication, without visual effect on people.

[0043] In particular implementation, Fourier coefficients at the frequencies may be

calculated for a plurality of display modes, where the Fourier coefficient denotes a level of the strength value of interference. Particularly, for all the possible pixels, when they are repeatedly displayed in a picture, Fourier coefficients of repeated signals in the frequencies transmitted in an MIPI DSI data line at this moment may be calculated, and display modes of pixels based on a minimum interference optimization may be selected according to the Fourier coefficients. It should be noted that the use of the Fourier coefficients is an embodiment of the present invention only. However, the present invention is not limited thereto, and other methods may be used for calculating the strength value of interference.

[0044] Figs. 5A and 5B are exemplary diagrams of the Fourier coefficients and display

modes of an embodiment of the present invention; wherein the horizontal coordinate is the RGB values, and the vertical coordinate is relative levels (in dB values) of a piece of harmonic interference falling into 3 GPP Band 20 of a radio receiver. As shown in Fig. 5A, when the RGB values are equal and are 0, 17, 34, 51, 68, 85, 102, 119, 136,..., the strength value of interference may be between -250 and -350 dB (which may actually be infinitesimal and are caused by a calculation error). As shown in Fig. 5B, when the RGB values are equal and are 37, 41, 73, 74, 82, 91, 107, 109,..., the strength value of interference may be between - 48 and -50 dB.

[0045] In this embodiment, in step 101 or 202, the selecting a display mode of a pixel

according to a strength value of interference induced in the frequency when the pixel is displayed may in particular include: selecting the display mode with a minimum strength value of interference, or selecting a display mode which has a strength value of interference less than a predetermined value and the display mode is closest to a display mode needing to be displayed.

[0046] For example, in a displayed picture, the RGB values of an original pixel needing to be displayed are (92, 92, 92), and the interference in this display mode to the radio communication is -36.5 dB; for RGB values (85, 85, 85), the interference in this display mode induced in this receiving band is -300 dB; and for RGB values (91, 91, 91), the interference in this display mode induced in this receiving band is -49.5 dB. Therefore, the display mode (85, 85, 85) with a minimum strength value of interference may be selected for the pixel, or the display mode ( 1, 91, 91) which produce interference of relatively small strength (such as less than a threshold value - 45 dB) and has a higher color similarity.

[0047] It should be noted that the above description is given only taking that the RGB values in a display mode are identical as an example. However, the present invention is not limited thereto, and the RGB values may be different from each other. And at the same time, in the consideration of an interference minimization target, a plurality of receiving bands and a plurality of MIPI DSI data harmonic frequencies in these bands may be analyzed simultaneously. Based on this, the compromised pixel RGB values with all the interference in these harmonic frequencies being not too intense may be determined. A particular manner of implementation may be determined as actually required.

[0048] It can be seen from the above embodiment that: a clock for the MIPI DSI

transmission is determined according to the band range of the radio communication; and for frequency falling into the band range of radio communication, a display mode of a pixel is selected according to the strength value of interference induced by display of the pixel. The invention may not only further reduce interference brought by the MIPI transmission to the radio communication, but also have obvious effect on those bands lower than 1 GHZ, increase no hardware cost, and occupy no design space.

[0049] Embodiment 2

[0050] An embodiment of the present invention provides an apparatus for reducing interference, which corresponds to the method of the above embodiment, and the identical parts shall not be described any further.

As shown in Fig. 6, the apparatus 600 includes: a selecting unit (also referred to as module, as is mentioned above) 601.

[0056] In particular implementation, the selecting unit 601 or the selecting unit 702 is

configured to: select a display mode with a minimum strength value of interference, or select a display mode which has a strength value of interference less than a predetermined value and is closest to a display mode needing to be displayed.

[0057] In this embodiment, the display mode may be RGB modes, and the display modes are different as RGB values are different. The RGB values in the display modes may be identical, or the RGB values are different from each other.

[0058] It can be seen from the above embodiment that: a clock for the MIPI display interface transmission is determined according to the band range of the radio communication; and for a frequency falling into a band range of radio communication, a display mode of a pixel is selected according to a strength value of interference induced by display of the pixel. The invention may not only further reduce interference brought by the MIPI transmission to the radio communication, but also have effect on those bands lower than 1 GHZ, increase no hardware cost, and occupy no design space.
