[0056] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0057] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0058] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0059] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0060] The image forming device is a device for forming an image on an imaging medium based on an imaging principle, including but not limited to a printer, a copier, a fax machine, a scanner, a multifunction device, an electrostatic printing device and other devices that can realize the image forming function.

[0061] The image forming device mostly contains a scanning component, such as a scanning analog front end of a CCD or CMOS image sensor. When the image forming device performs a copying or scanning job, the scanning component performs image acquisition on the job and outputs image data. At present, the image data output by the scanning component of the image forming device is mainly transmitted in a TTL mode, which affects the transmission efficiency. If the scanning component of the image forming device is changed to output image data in an LVDS (Low Voltage Differential Signaling) mode, how to process the image data becomes a problem to be solved. In order to solve the problem, the embodiments of the present application provide an image data processing method, which can improve the transmission efficiency of image data and can provide support for subsequent image forming jobs.

[0062] Referring toFigure 1 A flow chart of an image data processing method provided by an embodiment of the present application. Figure 1 The method is applied to a processing chip, and the processing steps of the method include:

[0063] 101, obtaining differential data output by a scanning analog front end.

[0064] 102, sorting parameters in the differential data according to preset configuration information to obtain image data to be detected after sorting.

[0065] 103, detecting the image data to be detected for validity and color information.

[0066] 104, outputting processed image data.

[0067] The differential data is image data in LVDS format.

[0068] The configuration information is set according to the type of the scanning analog front end. The corresponding configuration information is set according to different types of scanning analog front ends, and then the differential data is adaptively identified and processed when the differential data is received, so as to meet the multiple requirements of subsequent image processing on the data. Furthermore, it can be adapted to the differential data output by different types of scanning analog front ends to help compatible with the acquisition and processing of multiple differential data. The configuration is flexible and easy to implement, thereby improving the efficiency of image data transmission and processing and improving the system performance.

[0069] The configuration information can include the number of bits of the differential data. In addition, the image data to be detected includes pixel data and control information. The configuration information can be configured in advance to include the number of bits and the position of the pixel data to be included in the image data to be detected, and the number of bits and the position of the control information. It can be understood that the number of bits of the pixel data refers to the number of bit positions occupied by the pixel data in a frame of the image data to be detected, which is equivalent to the number of bits of the pixel data in the differential data output by the scan analog front end. The position of the pixel data can be the position of the bit positions occupied by the pixel data in the differential data, the position in the image to be detected, or the position in the data after intermediate conversion (such as serial-parallel conversion) of the differential data. The number of bits of the control information refers to the number of bit positions occupied by the control information in a frame of the image data to be detected, which is equivalent to the number of bits of the control information in the differential data output by the scan analog front end. The position of the control information can be the position of the bit positions occupied by the control information in the differential data, the position in the image to be detected, or the position in the data after intermediate conversion (such as serial-parallel conversion) of the differential data. Further, the bit positions occupied by the control information can be used to represent the line head information, validity information, and color information. Among them, the line head information can be used to determine whether the image data to be detected of each frame is data of the same line, the validity information is used to determine whether the image data to be detected is valid data, and the color information is used to represent the color of the image data to be detected.

[0070] In step 102, the parameters in the differential data can be sorted in the corresponding positions according to the configuration information to obtain the image data to be detected matching the configuration information. After obtaining the image data to be detected, the validity of the image data to be detected and the color information in the image data to be detected can be detected according to the configuration information, and the processed image data is output.

[0071] The embodiment of the present application is based on the differential data output by the image sensor, sorts the differential data according to the preset configuration information to obtain the image data to be detected, and outputs the processed image data after detection. The embodiment of the present application is suitable for image forming equipment, can process the differential data output by the image sensor through the preset configuration information, and can improve the compatibility of the scan analog front end of various types, and the data processing efficiency and reliability.

[0072] Referring to Figure 2 The flowchart of another image data processing method provided by the embodiment of the present application is shown in FIG. 2. As shown in FIG. 2, the processing steps of the method include: Figure 2

[0073] 201, obtaining the differential data output by the scan analog front end.

[0074] 202, performing serial-parallel conversion on the differential data to obtain parallel output data.​

[0075] 203, sorting the parameters in the parallel output data into corresponding positions according to preset configuration information to obtain the to-be-detected image data.

[0076] The control information of the to-be-detected image data includes to-be-detected header information, to-be-detected validity information and to-be-detected color information. The preset configuration information includes configuration header information, configuration validity information and configuration color information.

[0077] 204, detecting whether the to-be-detected header information of the to-be-detected image data matches the configuration header information in the configuration information. If yes, step 205 is performed; if not, the to-be-detected image data is invalid pixel data and is discarded.

[0078] 205, detecting whether the to-be-detected validity information of the to-be-detected image data matches the configuration validity information in the configuration information. If yes, the to-be-detected image data is valid data and step 206 is performed. If not, the to-be-detected image data is invalid data and is discarded.

[0079] 206, detecting the to-be-detected color information of the to-be-detected image data according to the configuration color information to obtain processed image data.

[0080] 207, sending the processed image data to an AXI (Advanced eXtensible Interface) bus in a burst mode.

[0081] The preset configuration information includes: the number of differential data, the number of bits of pixel data and the position of the pixel data in the parallel output data, the number of bits of control information and the position of the control information in the parallel output data. Specifically, the control information can include header information, validity information and color information. The header information can include a horizontal synchronization signal and a same-line indication signal, and the positions of the horizontal synchronization signal and the same-line indication signal in the parallel output information. The validity information can include a validity flag and the position of the validity flag in the parallel output information. The color information can include a color flag and the position of the color flag in the parallel output information.

[0082] In step 203, the parameters in the parallel output data can be sorted into corresponding positions according to the configuration information to obtain the to-be-detected image data.

[0083] In steps 204-206, validity and color information of the image data to be detected can be detected according to the configuration information. The line head information in the image data to be detected can be used to detect whether the image data to be detected in the current frame is the start of a new line of pixel data, or can be used to detect whether the current frame is the same line of pixel data as the previous frame. The validity information in the image data to be detected can be used to determine whether the image data to be detected in the current frame is valid. The color information in the image data to be detected can be used to determine the color represented by the image data to be detected in the current frame. After the color of the image data to be detected is determined, the image data to be detected is output as processed image data to the AXI bus and finally written into the system memory.

[0084] Referring to Figure 3 , a specific flowchart of an image data processing method provided by an embodiment of the present application is shown. As Figure 3 shown, the image data processing process of the embodiment of the present application includes:

[0085] 301, a differential clock signal is output by a scan analog front end.

[0086] As Figure 4 shown, the scan analog front end continuously outputs a differential clock signal CLK_P / CLK_N at a certain frequency. After the phase-locked loop module detects the differential clock signal at a stable frequency, a DLL_LOCK signal (i.e., a delay-locked loop identification signal) is output, and the DLL_LOCK signal is used to indicate that the output clock of the scan analog front end has stabilized. As Figure 4 shown, the DLL_LOCK signal remains high to indicate that the output clock of the scan analog front end has stabilized.

[0087] 302, three pairs of differential data are output by the scan analog front end.

[0088] As Figure 4 shown, under the differential clock signal, the scan analog front end outputs three pairs of differential data, namely DATA_P / DATA_N[0], DATA_P / DATA_N[1] and DATA_P / DATA_N[2]. As Figure 4 shown, DATA_P / DATA_N[0], DATA_P / DATA_N[1] and DATA_P / DATA_N[2] are transmitted bit by bit, and 7 bits of data are transmitted in each differential clock cycle.

[0089] 303, the differential data is converted from serial to parallel.

[0090] As Figure 4As shown, the DATA_P / DATA_N[0], DATA_P / DATA_N[1] and DATA_P / DATA_N[2] are converted into 3 groups of parallel output data DATA_RA, DATA_RB and DATA_RC respectively. The DATA_RA, DATA_RB and DATA_RC output 7b it data in parallel in each output clock (CLK_OUT, i.e. the received data processing clock) cycle, which are DATA_RA[6:0], DATA_RB[6:0] and DATA_RC[6:0] respectively. Correspondingly, in each CLK_OUT cycle, one frame of parallel output data includes 21b it, i.e. DATA_RA[6:0], DATA_RB[6:0] and DATA_RC[6:0].

[0091] 304, sorting the parameters in the 3 pairs of parallel output data according to the configuration information.

[0092] The configuration information includes: the number of pairs of differential data is 3; the number of pixel data contained in the output data of each frame of the scanning analog front end is 16b it, and the 16b it is located in {DATA_RA[6:3] and DATTA_RB[6:0], DATA_RC[4:0]} of the parallel output data; the number of control information contained in the output data of each frame is 5b it, and the 5b it is located in DATA_RA[2:0] and DATA_RC[6:5]. Among them, DATA_RC[5] of the control information indicates whether the pixel data is valid, and DATA_RC[6] and DATA_RA[0] of the control information represent color. Specifically, 00 represents red data, 01 represents green data, and 10 represents blue data. DATA_RA[1] represents a horizontal synchronization signal, which is used to indicate a start signal of a row of content output, and DATA_RA[2] is a same-row indication signal, which is used to indicate that the current frame and the previous frame belong to pixel data of the same row.

[0093] The image data to be detected after sorting according to the above configuration information is shown in Figure 5 As shown, one frame of image data to be detected includes 21b it, of which 16b it is pixel data and 5b it is control information. As shown in Figure 5 In one frame of image data to be detected, the pixel data occupies b it positions D0 to D15, and the control information occupies the remaining 5b it. The meanings of the b it positions occupied by the control information are as follows:

[0094] The CHA channel b it0 and the CHC channel b it6 are used to represent color.

[0095] CHA channel bit1 HS is used to represent a line synchronization signal, which is used to indicate a start signal of a line content start output.

[0096] CHA channel bit2 HD is used to represent a same line indication signal, which is used to indicate pixel data of a same line. When scanning an image, the image sensor scans a line of work content, and the corresponding output pixel data is usually one frame of HS, followed by N frames of HD. After the pixel data of the same line is transmitted, the next line HS and N frames of HD are output. That is, according to the HS and HD, the pixel data of the same line can be received.

[0097] CHC channel bit5 VD is a validity flag, which is used to indicate whether the pixel data of the current frame is valid.

[0098] 305, detecting whether the line head information on the CHA channel bit1 and bit2 of the image data to be detected matches the configuration information. If it matches, step 306 is executed; if it does not match, the current image data to be detected is discarded.

[0099] The line head HS and HD in the configuration information can take values of 1, 0 to represent data of the same line, values of 0, 0 to represent a start frame, and values of 1, 1 to represent that the line head does not match the configuration information.

[0100] As shown in FIG. 3, the HS and HD on the CHA channel bit1 and bit2 are 1, 1 respectively, so that the line head of the current data frame does not match the configuration information, the current data frame is invalid pixel data and is discarded. Figure 6 As shown in FIG. 3, the HS and HD on the CHA channel bit1 and bit2 are 0, 0 respectively, so that the current data frame is a start frame, the line head information matches the configuration information, and step 306 is continued. Figure 7 As shown in FIG. 3, the HS and HD on the CHA channel bit1 and bit2 are 1, 0 respectively, so that the line head information matches the configuration information, and step 306 is continued. Figures 8-10

[0101] 306, detecting the VD on the CHC channel bit5 of the image data to be detected. If the VD is 0, it indicates that the image data to be detected is valid pixel data and step 307 is executed; otherwise, the image data to be detected is invalid pixel data and is discarded.

[0102] As shown in FIG. 3, the VD on the CHC channel bit5 is 1, indicating that the current data frame is invalid pixel data. Figure 6 As shown in FIG. 3, the VD on the CHC channel bit5 is 0, indicating that the current data frame is valid pixel data. Figures 7-10

[0103] ​​307. Detect the values ​​of the CHC channel bit6 and CHA channel bit0 of the image data to be detected in order to determine the color of the image data to be detected.

[0104] in, Figure 7 The start frame is a signal that initiates image data processing, eliminating the need to detect its color information.

[0105] like Figure 8 As shown, the values ​​of bit6 in the CHC channel and bit0 in the CHA channel are 00, indicating that the color of the current frame is red, that is, the pixel data stored in bits D0 to D15 is red pixel data. In one example, D0 to D15 can store red pixel data R0[0]-R0[7] and R1[0]-R1[7]. Figure 9 As shown, the values ​​of bit6 in the CHC channel and bit0 in the CHA channel are 0 and 1, indicating that the color of the current frame is green. That is, the pixel data stored in bits D0 to D15 is green pixel data. In one example, D0 to D15 can store green pixel data G0[0]-G0[7] and G1[0]-G1[7]. Figure 10 As shown, the value of bit6 in the CHC channel and bit0 in the CHA channel is 10, indicating that the color of the current frame is blue. That is, the pixel data stored in bits D0 to D15 is blue pixel data. In one example, D0 to D15 can store blue pixel data B0[0]-B0[7] and B1[0]-B1[7].

[0106] exist Figures 8-10 In the example, the three frames of image data contain information for two pixels. For example, pixel 1 corresponds to R0[0:7]-G0[0:7]-B0[0:7], and pixel 2 corresponds to R1[0:7]-G1[0:7]-B1[0:7]. In this example, two pixel information can be transmitted through three frames of image data. It can be understood that the pixel information carried by D0-D15 in each frame of image data can be configured as needed to achieve the purpose of flexibly transmitting pixel information.

[0107] 308, Cache the processed image data.

[0108] Among these methods, the processed image data can be cached according to certain rules based on the detected color information. For example, the processed image data can be cached in RGB or BGR order.

[0109] 309, when the amount of cached data reaches a certain value, the cached data is sent to the AXI bus in a burst form based on the first-in first-out principle, and finally written into the system memory. When the processed image data is output, the data can be output in a pixel-by-pixel, line-by-line, or color plane manner.

[0110] The method of the embodiment of the application supports input and processing conversion of multiple pairs of LVDS data. Moreover, the method of the embodiment of the application supports multiple working modes, such as one pixel per frame, two pixels per three frames, and the like. Figures 8-10 When the data is output, the data output format of the embodiment of the application is flexible and configurable, such as pixel-by-pixel, line-by-line, or color plane.

[0117] The data sorting module is configured to sort the parameters in the parallel output data in corresponding positions according to the configuration information to obtain the image data to be detected.

[0118] The configuration information further includes configuration header information, configuration validity information and configuration color information.

[0119] The header detection module is configured to detect whether the to-be-detected header information of the image data to be detected matches the configuration header information in the configuration information.

[0120] The pixel processing module is configured to detect whether the to-be-detected validity information of the image data to be detected matches the configuration validity information in the configuration information, and when the to-be-detected header information matches the configuration header information and the to-be-detected validity information matches the configuration validity information, determine that the image data to be detected is valid data, and perform color detection on the to-be-detected color information in the valid data according to the configuration color information in the configuration information.

[0122] The data output module is configured to send the buffered processed image data to the AXI bus in a burst form when the processed image data in the data buffer module reaches a set condition.

[0123] In this embodiment, the data output module is a memory access module, i.e., an SDMA module, which can select whether to configure an enable burst operation to configure the maximum burst number and configure a single burst length according to the congestion of the system bus, so that the data output module can send the buffered processed image data to the AXI bus in a burst form when the processed image data in the data buffer module reaches a set condition.
