Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a data transmission method, which is applied to a sending end, where the sending end transmits data to a receiving end through a MIPI interface of a mobile industry processor, where the MIPI interface may be an image transmission interface or an LCM interface, and the method includes:

step 101, acquiring a mark bit of original data; the original data zone bit is a data zone bit of original RAW data to be transmitted.

The data to be transmitted may be original RAW data; specifically, the RAW data is a RAW image file, i.e., RAW data that is not processed, and the image sensor converts the captured light source signal into RAW data of a digital signal. RAW data includes captured RAW information of an image sensor, and some metadata generated by photographing, such as shutter speed, aperture value, and white balance.

When the MIPI interface transmits data, a cycle period T exists, and n data are transmitted in each period T; in each data transmitted in different periods T, there are either several identical data bits, or the first several data bits have strict similarity (i.e. the similarity is higher than a preset threshold), and the data bits are original data flag bits. For example, the data to be transmitted in one period includes 40 bits (bit), ABCDEFGHXX XXXXXXXXXX xxxxxxxxxxxxxx respectively; ABCDEFGH is the original data flag bit, and X indicates that the data on the bit is randomly 0 or 1; for example, the data transmitted in each cycle may be as shown in the first example below:

period 1: 1110100001111000101111010110100011001000, respectively;

period 2: 1110100011111000100001110110100000010010, respectively;

period 3: 1110100000000100011010011110100001011010, respectively;

period 4: 1110100011111000011010111110100011010010, respectively;

period 5: 1110100010000100001101100001100011000011, respectively;

as can be seen from the above data, the first 8 bits of each data are "11101000", and then 11101000 is the flag bit of the original data to be transmitted in the period.

And step 102, adjusting the original data zone bits according to a preset coding mode to obtain target data zone bits.

When ABCDEFGH is the same or has strict similarity in each period, the generated spectrum also has a certain periodicity, and therefore, the transmitted data may generate a spectrum peak at a fixed frequency domain position; if a strong signal power is generated just in the working frequency band of the electronic equipment (the electronic equipment where the sending end and the receiving end are located), the electromagnetic interference on the electromagnetic sensing part of the electronic equipment is serious; and different digital combinations have different corresponding frequency domains and frequency spectrums.

As a second example, as shown in FIG. 2, FIG. 2 is a simulated spectrum of "111 XXXXX"; FIG. 4 is a simulated spectrum for data "001 XXXXX"; wherein for frequency point m3, its frequency point value is 2.133GHz (gigahertz), and its signal power is-34.079 dB in FIG. 2; the signal power is-45.675 dB (decibels) in FIG. 3; if the electronic device communicates in the B1 frequency band, the receiving frequency band frequency is 2110MHz-2170MHz, and it is assumed that the originally adopted 111XXXXXX coding mode causes the receiver band to receive 2.133GHz noise energy; after the coding mode is changed into the 001XXXXX coding mode, the noise energy on the 2.133GHz frequency point is reduced by 11dB, and the sensitivity is also improved.

Therefore, the original data zone bits are recoded in a preset coding mode to obtain different target data zone bits, so that the data zone bits in each period are not the same or strictly similar and are possibly changed into random data; the performance of the electromagnetic sensitive device can be improved by adjusting the data combination form of the original data zone bit and changing the frequency spectrum of the original data zone bit.

And 103, obtaining target RAW data according to the target data zone bit.

After the original data zone bit is replaced by a target data zone bit, carrying the target data zone bit on RAW data and sending the RAW data to a receiving end, and after the receiving end receives the RAW data, decrypting the target data zone bit according to a decoding rule corresponding to the preset coding mode to obtain the original data zone bit and finish data transmission; therefore, if the performance of the electromagnetic sensitive device is detected to be poor by the electronic equipment, the sending end can be controlled to switch the coding mode, and the energy radiation of the MIPI interface to the electromagnetic sensitive device is reduced.

In the above embodiment of the present invention, the sending end obtains the flag bit of the original data; adjusting the original data zone bits according to a preset coding mode to obtain target data zone bits; the target data zone bit replaces the original data zone bit, the frequency spectrum of the original data zone bit is changed, the frequency spectrum interference of the MIPI signal in a communication frequency band and the energy radiation of the electromagnetic sensitive device are reduced, and the performance of the electromagnetic sensitive device of the electronic equipment is improved. The embodiment of the invention solves the problem that the MIPI interface of the electronic equipment is easy to cause energy radiation to the electromagnetic sensing element.

Optionally, in this embodiment of the present invention, step 102 includes:

and inputting the original data zone bit to a preset coding module, and adjusting the original data zone bit through the preset coding module.

The device comprises a preset coding module and a preset decoding module, wherein the preset coding module is used for coding the zone bit of the original data, and the preset coding module changes a coding scheme.

Optionally, in this embodiment of the present invention, step 102 includes:

adjusting the position of the original data zone bit in the original RAW data according to a first preset coding mode;

and/or the presence of a gas in the gas,

and adjusting the coding value of at least part of data in the original data zone bit according to a second preset coding mode.

Wherein, adjusting the position of the original data flag bit in the original RAW data adjusts the order of data in the RAW data.

And adjusting the encoding value of at least part of the data in the original data flag bit, namely replacing the encoding value of part of the data with other values, such as inverting part of the data in the original data flag bit.

The above coding method includes three cases, where the first case is to invert part of the data in the flag bits of the original data, for example, if the first 4 bit bits are inverted, ABCDEFGH is mapped as

EFGH, as in 11101000 maps to 00011000;

the second case is: adjusting by adjusting an order of data in the RAW data; for example, the ABCDEFGGHXXXXXXXXXXXXXXXXX XXXXXXXXXXXXX combination is adjusted to XXXXXXXXXXXAB XXXXXXXXXXXXCD XXXXXXXXXXXXXXXXXXXXXXGH;

in case three, case one and case two can also be combined, i.e. the partial inversion is done simultaneously with the adjustment of the order.

Further, referring to fig. 4, in the embodiment of the present invention, the preset encoding module includes a D flip-flop and a logic gate module for executing the first operation logic;

the first input of the logic gate module is the original data zone bit, and bit data in the original data zone bit in fig. 5 is input into the first input a bit by bit;

the second input of the logic gate module is an initial preset value or the output of the D trigger, and the input of the D trigger is the output of the logic gate module; the secondary state of the D flip-flop depends on the state of the D end before triggering, namely, the secondary state is D. Therefore, it has two functions of setting 0 and setting 1. In fig. 5, if the output C is 1, the D flip-flop inputs data to the second input B; when the output C is 0, the D flip-flop does not input data to the second input B, and the second input D maintains the data in the previous state.

The output of the preset encoding module is the output of the logic gate module, and as shown in fig. 5, the data of the output C is the target encoding module and can be directly input to the receiving end.

The logic gate module can be a double-input and single-output logic device, such as an exclusive-or gate and an exclusive-or gate; or an exclusive or gate, an exclusive or gate and other logic device combinations, such as an exclusive or gate + not gate; or other logic gate modules; the logic gate module performs the following first operation logic, as shown in table 1:

table 1:

first input A	Second input B	Output C (type 1)	Output C (type 2)
				1	0	1	0
1	1	0	1
				0	0	1	0
0	1	0	1

That is, when the first input a is equal to 1 and the second input B is equal to 0, the output C may be 1 or 0.

Taking the logic gate module as an exclusive-or gate as an example, the flag bits of the original data are 1, 0, 1, and after being serially and sequentially input through the logic gate module, the initial first input a is 1, if the initial value of the second input B is 0, the output C is 1, after passing through the delay device (D flip-flop),

the new second input B is equal to 1, and at the same time, the input a is equal to 0 (next bit data of MIPI data), the output C is equal to 1, … …, and the flow is sequentially circulated, and the flag bit of the target data after final processing is 1101.

When the ABCDEFGHGXX XXXXXXXXXXXXXXXXXXXXXXXX is re-encoded by the pre-determined encoding module, the original fixed data at the ABCDEFGH position is transformed into random data, and the energy of the peak in the spectrum will be reduced. In all frequency bands, the overall noise energy in a certain bandwidth is reduced compared with the noise energy before being coded.

Referring to fig. 5, another embodiment of the present invention provides a data transmission method, which is applied to a receiving end that receives data transmitted by a transmitting end through a MIPI interface of a mobile industry processor, where the MIPI interface may be an image transmission interface or an LCM interface, and the method includes:

step 501, receiving target RAW data sent by an MIPI (mobile industry processor interface) of a mobile industry processor, and acquiring a target data zone bit of the target RAW data; the target data zone bit is obtained by adjusting an original data zone bit of the MIPI according to a preset coding mode; the target data flag bit is different from the original data flag bit.

The receiving end receives RAW data sent by the sending end through the MIPI; RAW data is RAW data, i.e., RAW data obtained by converting a captured light source signal into a digital signal by an image sensor. RAW data includes captured RAW information of an image sensor, and some metadata generated by photographing, such as shutter speed, aperture value, and white balance.

A receiving end receives RAW data and then acquires a target data zone bit therein, wherein the target data zone bit is obtained by adjusting an original data zone bit of the MIPI according to a preset coding mode; specifically, when a sending end transmits data through an MIPI interface, a cycle period T exists, and n data are transmitted in each cycle T; in each data transmitted in different periods T, there are either several identical data bits, or the first several data bits have strict similarity (i.e. the similarity is higher than a preset threshold), and the data bits are original data flag bits. For example, the data to be transmitted in one period includes 40 bits (bit), ABCDEFGHXX XXXXXXXXXX xxxxxxxxxxxxxx respectively; ABCDEFGH is the original data flag bit, and X indicates that the data on the bit is randomly 0 or 1; for example, the data transmitted in each cycle may be as shown in the first example below:

period 1: 1110100001111000101111010110100011001000, respectively;

period 2: 1110100011111000100001110110100000010010, respectively;

period 3: 1110100000000100011010011110100001011010, respectively;

period 4: 1110100011111000011010111110100011010010, respectively;

period 5: 1110100010000100001101100001100011000011, respectively;

As a second example, as shown in FIG. 2, FIG. 2 is a simulated spectrum of "111 XXXXX"; FIG. 3 is a simulated spectrum for data "001 XXXXX"; wherein, for the frequency point m3, the frequency point value is 2.133GHz (gigahertz), the signal power is-34.079 dB in FIG. 2, and the signal power is-45.675 dB in FIG. 3; if the electronic device communicates in the B1 frequency band, the receiving frequency band frequency is 2110MHz-2170MHz, and it is assumed that the originally adopted 111XXXXXX coding mode causes the receiver band to receive 2.133GHz noise energy; after the coding mode is changed into the 001XXXXX coding mode, the noise energy on the 2.133GHz frequency point is reduced by 11dB, and the sensitivity is also improved.

Therefore, the sending end recodes the original data zone bits in a preset coding mode to obtain different target data zone bits, so that the data zone bits in each period are not the same or strictly similar and are possibly changed into random data; the performance of the electromagnetic sensitive device can be improved by adjusting the data combination form of the original data zone bit and changing the frequency spectrum of the original data zone bit.

Step 502, decoding the target data zone bit according to the preset coding mode to obtain the original data zone bit.

After the receiving end receives the RAW data, the target data zone bit is decrypted according to a decoding rule corresponding to the preset coding mode to obtain the original data zone bit, and data transmission is completed; therefore, if the performance of the electromagnetic sensitive device is detected to be poor by the electronic equipment, the sending end can be controlled to switch the coding mode, and the energy radiation of the MIPI interface to the electromagnetic sensitive device is reduced.

Optionally, in an embodiment of the present invention, step 502 includes one of the first or second ways, wherein,

the first method is as follows: inputting the target data zone bit into a preset decoding module, and decoding the original data zone bit through the preset decoding module;

the second method comprises the following steps: and decoding the target data zone bit according to a first preset coding mode and/or a second preset coding mode.

The first mode includes a preset decoding module for decoding the target data flag bit, and if the preset encoding module at the transmitting end changes the encoding scheme, the receiving end decodes the target data flag bit by using the decoding module corresponding to the preset encoding module.

The second mode includes three cases, where the first mode is a first preset coding mode, and the first preset coding mode may be that a preset coding module at the transmitting end inverts part of the data in the original data flag bits, for example, if the first 4 bits are inverted, ABCDEFGH is mapped as ABCDEFGH

EFGH, as mapped 11101000; the receiving end restores the inverted bit, that is, the bit is restored

EFGH is reduced to ABCDEFGH. 11101000 is reduced as 00011000.

Case two is a second predetermined encoding scheme: the second preset encoding manner may be that the transmitting end adjusts by adjusting an order of data in the RAW data; for example, the ABCDEFGXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX combination is adjusted to XXXXXXXXXXXAB XXXXXXXXXXCD XXXXXXXXXXXXEF XXXXXXXXGH; the receiving end restores the data by adopting a reverse restoring mode.

In case three, the first and second cases may also be combined, that is, the first preset encoding mode and the second preset encoding mode are performed simultaneously, for example, partial inversion and adjustment sequence are performed simultaneously, and the receiving end restores the first preset encoding mode and the second preset encoding mode according to an adjustment scheme reverse to the first preset encoding mode.

Further, referring to fig. 6, in the embodiment of the present invention, the preset decoding module includes a D flip-flop and a logic gate module executing a second operation logic;

the first input of the logic gate module is the target data zone bit, and bit data in the target data zone bit in fig. 6 is input into the first input a bit by bit;

the second input of the logic gate module is an initial preset value or the output of the D trigger; the input of the D trigger is the output of the logic gate module; the secondary state of the D flip-flop depends on the state of the D end before triggering, namely, the secondary state is D. Therefore, it has two functions of setting 0 and setting 1. In fig. 7, if the output C is 1, the D flip-flop inputs data to the second input B; when the output C is 0, the D flip-flop does not input data to the second input B, and the second input D maintains the data in the previous state.

And the output of the preset decoding module is the output of the logic gate module.

The logic gate module can be a double-input and single-output logic device, such as an exclusive-or gate and an exclusive-or gate; or an exclusive or gate, an exclusive or gate and other logic device combinations, such as an exclusive or gate + not gate; or other logic gate modules; the logic gate module executes the following second operation logic, as shown in table 2:

table 2:

first input A	Second input B	Output C (type 1)	Output C (type 2)
				1	0	1	0
0	1	1	1
				1	0	0	0
0	1	0	1

Taking the logic gate module as an exclusive-or gate as an example, the flag bits of the original data are 1, 0, 1 and 1, after the original data are serially and sequentially input and pass through the logic gate module of the preset encoding module, the initial first input a is 1, if the initial value of the second input B is 0, the output C is 1, after passing through the delay device (D flip-flop),

the new second input B is equal to 1, and at the same time, the input a is equal to 0 (next bit data of MIPI data), the output C is equal to 1, … …, the process is sequentially circulated, and the flag bit of the target data after final processing is yes, the data received by the receiving end is yes.

If the logic gate module at the receiving end is also an exclusive-or gate, after sequentially inputting the target data flag bits of 1, 0 and 1 in series and passing through the logic gate module of the preset decoding module, the initial first input A is 1, if the initial value of the second input B is 0, the output C is 1, after passing through the delay device (D trigger),

the new second input B is equal to 1, and the input a is equal to 1 (next bit data of MIPI data), the output C is equal to 0, … …, the process is sequentially circulated, and the target data flag after final processing is yes, so that the data received by the receiving end is 1, 0, 1.

When the ABCDEFGHXX xxxxxxxxxxxxxxxxxx is re-encoded by the pre-encoding module, the original fixed data at the ABCDEFGH position is converted into random data, and the energy of the peak on the spectrum received by the receiving end is reduced. In all frequency bands, the overall noise energy in a certain bandwidth is reduced compared with the noise energy before being coded.

In the above embodiment of the present invention, the receiving end receives the target data flag bit after the sending end adjusts the original data flag bit according to a preset encoding mode; and decoding the target data zone bit according to the preset coding mode to obtain the original data zone bit, so that the original data zone bit is replaced by the target data zone bit, the frequency spectrum of the original data bit is changed, the frequency spectrum interference of the MIPI signal in a communication frequency band and the energy radiation of an electromagnetic sensitive device are reduced, and the performance of the electromagnetic sensitive device of the electronic equipment is improved. The embodiment of the invention solves the problem that the MIPI interface of the electronic equipment is easy to cause energy radiation to the electromagnetic sensing element.

Referring to fig. 7, an embodiment of the present invention provides a data transmission method, which is applied to an electronic device, where the electronic device includes a sending end and a receiving end, where the sending end transmits data to the receiving end through a MIPI interface of a mobile industry processor, where the MIPI interface may be an image transmission interface or an LCM interface;

the method comprises the following steps:

step 701, in a case that a received signal strength indication RSSI of a receiver module of the electronic device is higher than a preset RSSI threshold value.

The Received Signal Strength Indication (RSSI) represents the overall Strength of the in-band Signal Received by the current receiver module, and may reflect the Received noise Strength of the receiver module under the current coding scheme, and a lower value thereof represents that the interference noise Received by the peripheral device (electromagnetic sensitive device) of the MIPI interface is lower, and the sensitivity performance is better. The preset RSSI threshold value is the preset highest value, if the current RSSI exceeds the preset RSSI threshold value, the fact that under the current MIPI interface coding mode, large interference noise exists in a receiver module band can cause sensitivity reduction

Therefore, the electronic device performs code switching when it detects that the RSSI of its receiver module is above a preset RSSI threshold.

Step 702, sending a switching indication message to the sending end, and indicating the sending end to adjust the original data zone bit according to a preset coding mode to obtain the target data zone bit.

When the electronic equipment executes coding switching, the sending end is instructed to adjust the original data zone bit according to a preset coding mode to obtain a target data zone bit; when a sending end transmits data through an MIPI interface, a cycle period T exists, and n data are transmitted in each period T; in each data transmitted in different periods T, there are either several identical data bits, or the first several data bits have strict similarity (i.e. the similarity is higher than a preset threshold), and the data bits are original data flag bits. For example, the data to be transmitted in one period includes 40 bits (bit), ABCDEFGHXX xxxxxxxxxxxxxxxxxxxxxx, xxxxxxxxxxxxxx, respectively; ABCDEFGH is the original data flag bit, and X indicates that the data on the bit is randomly 0 or 1; for example, the data transmitted in each cycle may be as shown in the first example below:
