[Figure 8] This figure shows the YC data and the waveform of the resulting video changes in this embodiment.

[0008] [Detailed explanation] Preferred embodiments of the present disclosure are described in detail below. In the following descriptions and accompanying drawings, substantially identical or equivalent parts are denoted by the same reference numerals.

[0009] Figure 1 is a block diagram showing the configuration of a video signal transmission system 100 according to an embodiment of the present disclosure. The video signal transmission system 100 consists of a camera module 10 and a display module 20.

[0010] The camera module 10 includes an imaging unit 11, a RAW / YC conversion unit 12, a control unit 13, a data sorting and processing unit 14, and an analog transmission unit 15.

[0011] The imaging unit 11 includes a lens and an image sensor, and supplies RAW data obtained by imaging a subject to the RAW / YC conversion unit 12. In the RAW data, three pixels—red, green, and blue—are arranged in a Bayer array. In the following description, the red pixel will also be referred to as pixel R, the green pixel as pixel G, and the blue pixel as pixel B. In this embodiment, one unit of RAW data is composed of one pixel R, one pixel B, and two pixels G.

[0012] The RAW / YC conversion unit 12 converts the RAW data supplied from the imaging unit 11 into YC data and supplies it to the data rearrangement processing unit 14. In this embodiment, the RAW / YC conversion unit 12 generates YC data based on RAW data with 4 pixels horizontally and 2 pixels vertically (i.e., 2 rows and 4 columns).

[0013] In this embodiment, the RAW / YC conversion unit 12 generates YC data by performing a YC422 conversion using the following conversion formula.

[0014] Y00=G00 Y01=G01 Y10=G10 Y11=G11 G0 = (G00 + G01) / 2 G1 = (G10 + G11) / 2 Y0 = (5G0 + 2R0 + B0) / 8 Y1 = (5G1 + 2R1 + B1) / 8 Cb0 = B0 - Y0 Cb1 = B1 - Y1 Cr0 = R0 - Y0 Cr1 = R1 - Y1 Figure 2 shows an example of RAW data before YC conversion and YC data after YC conversion by the RAW / YC conversion unit 12. Here, the example shows the case where YC conversion is performed every two pixel blocks of one unit consisting of 2 pixels horizontally × 2 pixels vertically (i.e., every 4 pixels horizontally × 2 pixels vertically).

[0015] In the RAW data before YC conversion, pixel B0 and pixel G01 of the first unit are sequentially and consecutively arranged in the first line in the horizontal direction (row direction), followed by pixel B1 and pixel G11 of the second unit. Further, pixel G00 and pixel R0 of the first unit are sequentially and consecutively arranged in the second line in the horizontal direction (row direction), followed by pixel G10 and pixel R1 of the second unit.

[0016] In the YC data after YC conversion, Y00 and Y01 which are Y data of the first unit, and Y10 and Y11 which are Y data of the second unit are sequentially and consecutively arranged in the first line in the horizontal direction (row direction). Further, Cr0 which is Cr data of the first unit and Cb0 which is Cb data of the first unit, and Cr1 which is Cr data of the second unit and Cb1 which is Cb data of the second unit are sequentially and consecutively arranged in the second line in the horizontal direction (row direction).

[0017] Referring again to FIG. 1, the control unit 13 controls the data rearrangement processing performed by the data rearrangement processing unit 14 and the analog transmission processing performed by the analog transmission unit 15.

[0018] The data rearrangement processing unit 14 performs the data rearrangement processing according to a predetermined data rearrangement method under the control of the control unit 13.

[0019] Figure 3 shows an example of data rearrangement processing performed by the data rearrangement processing unit 14. The data rearrangement processing unit 14 rearranges the Y data located in the first row horizontally (row direction) of the YC data that has undergone YC conversion by the RAW / YC conversion unit 12, such that the first Y data in the first unit (first luminance data) and the first Y data in the second unit (first luminance data) are placed consecutively, followed by the second Y data in the first unit (second luminance data) and the second Y data in the second unit (second luminance data). In the example shown in Figure 3, the first Y data in the first unit of the YC data before sorting is Y00, the second Y data is Y01, the first Y data in the first unit is Y10, and the second Y data is Y11. Therefore, the data sorting processing unit 14 sorts the Y data so that the first Y data of each unit, Y00 and Y10, are consecutive, followed by the second Y data of each unit, Y01 and Y11, which are consecutive.

[0020] Furthermore, the data rearrangement processing unit 14 rearranges the Cb data and Cr data located in the second row horizontally (row direction) of the YC data that has undergone YC conversion by the RAW / YC conversion unit 12, so that the Cr data (first luminance data) of the first unit and the second unit are arranged consecutively, followed by the Cb data (second luminance data) of the first unit and the second unit, followed by the Cb data (second luminance data) of the first unit, followed by the Cr0 and Cb0 of the first unit in the CbCr data before rearrangement. Therefore, the data rearrangement processing unit 14 rearranges the Cb data and Cr data so that the Cr data of each unit, Cr0 and Cr1, are arranged consecutively, followed by the Cb data of each unit, Cb0 and Cb1, followed by the Cb data of each unit, followed by the Cb data of each unit, Cb0 and Cb1, followed by the Cb data of each unit, followed by the Cb data of each unit, Cb0 and Cb1, followed by Cb

[0021] As a result, the rearranged YC data will have a data array in which Y00, Y10, Y01, and Y11 are arranged sequentially in the first horizontal row, and Cr0, Cr1, Cb0, and Cb1 are arranged sequentially in the second horizontal row.

[0022] Note that Figure 3 shows an example where data is rearranged for every two units of YC data (i.e., YC data corresponding to two pixel blocks consisting of 2 pixels horizontally and 2 pixels vertically), but the unit of rearrangement is not limited to this.

[0023] Figure 4 compares the case where YC data for one line is rearranged as a whole line and the case where it is rearranged in increments of two units.

[0024] As shown in the upper part of Figure 4, when performing data rearrangement processing for one line of YC data as a whole, the data rearrangement processing unit 14 rearranges the Y data located in the first row in the horizontal direction (row direction) so that the first Y data of each unit (i.e., the first luminance data) is arranged consecutively for one line, followed by the second Y data of each unit (i.e., the second luminance data) being arranged consecutively for one line. As a result, Y00, Y10, ..., Yn0 are arranged consecutively, followed by Y01, Y11, ..., Yn1.

[0025] Furthermore, when performing data rearrangement on an entire line of YC data, the data rearrangement processing unit 14 rearranges the Cb data and Cr data located in the second row horizontally (row direction) so that all of the Cr data (i.e., the first color difference data) for each unit are arranged consecutively, followed by all of the Cb data (i.e., the first color difference data) for each unit being arranged consecutively. As a result, Cr0, Cr1, ..., Crn are arranged consecutively, followed by Cb0, Cb1, ..., Cbn are arranged consecutively.

[0026] As shown in the lower part of Figure 4, when the data rearrangement process for one line of YC data is performed every two units, the data rearrangement processing unit 14 rearranges the Y data located in the first row horizontally (row direction) so that the first Y data (i.e., the first luminance data) in a consecutive unit is arranged twice in a row, followed by the second Y data (i.e., the first luminance data) in the same consecutive unit twice in a row, and thereafter the first Y data and the second Y data are arranged alternately in pairs. As a result, the Y data is arranged in the order of Y00, Y10, Y01, Y11, Y20, Y30, Y21, ..., Yn0, Y(n-1)1, Yn1.

[0027] Furthermore, when the data rearrangement process for one line of YC data is performed every two units, the data rearrangement processing unit 14 rearranges the Cr data and Cb data located in the second row horizontally (row direction) so that two consecutive Cr data (i.e., first color difference data) in a consecutive unit are followed by two consecutive Cb data (i.e., second color difference data) in the same consecutive unit, and thereafter Cr data and Cb data are arranged alternately in pairs. As a result, the Cb data and Cr data are arranged in the order of Cr0, Cr1, Cb0, Cb1, Cr2, Cr3, Cb2, ..., Crn, Cb(n-1), Cbn.

[0028] Referring again to Figure 1, the analog transmission unit 15 includes a DAC (Digital to Analog Converter) and converts the Y data and CrCb data, which have undergone data reordering processing by the data reordering processing unit 14, into analog signals, which are then transmitted to the display module 20.

[0029] The display module 20 includes an analog receiving unit 21, a data reverse sorting processing unit 22, a video data conversion unit 23, an RGB conversion unit 24, and a display unit 25.

[0030] The analog receiver 21 receives the analog signal transmitted from the camera module 10. The analog receiver 21 includes an ADC (Analog to Digital Converter) and converts the analog signal into digital data, which is then supplied to the data inverse reordering processing unit 22. In this embodiment, the YC data obtained by converting the analog signal is supplied to the data inverse reordering processing unit 22.

[0031] The data reverse sorting processing unit 22 performs a data sorting process (hereinafter also referred to as data reverse sorting) on ​​the YC data supplied from the analog receiving unit 21 to return the data arrangement, which has been rearranged by the data sorting processing unit 14 of the camera module 10, back to its original arrangement.

[0032] Figure 4 shows an example of the data reverse sorting process performed by the data reverse sorting processing unit 22.

[0033] The data reverse sorting processing unit 22 sorts the reordered YC data received via the analog receiver 21 in the reverse order of the sorting process performed by the data sorting processing unit 14 of the camera module 10, so that the original arrangement of YC data is achieved. In the example shown in Figure 4, the data reverse sorting processing unit 22 sorts the Y data in the first horizontal row so that the first Y data is Y00, the second Y data is Y01, the third Y data is Y10, and the fourth Y data is Y11. It also sorts the CbCr data in the second horizontal row so that the first data is Cr0, the second data is Cb0, the third data is Cr1, and the fourth data is Cb1.

[0034] Referring again to Figure 1, the video data conversion unit 23 converts the YC data, which has undergone reverse sorting processing by the data reverse sorting processing unit 22, into video data consisting of one pixel R, one pixel B, and two pixels G, similar to RAW data, and supplies it to the RGB conversion unit 24. In this embodiment, the video data conversion unit 23 performs the conversion from YC data to RAW data based on the conversion formula for YC422 conversion shown in the section on the RAW / YC conversion unit 12 above.

[0035] The RGB conversion unit 24 performs RGB conversion on the video data supplied from the video data conversion unit 23. Specifically, the RGB conversion unit 24 performs RGB conversion by interpolating data from surrounding pixels for each pixel of the video data to generate 8-bit R data, G data, and B data, respectively. The RGB conversion unit 24 supplies the RGB data generated by the RGB conversion to the display unit 25.

[0036] The display unit 25 is composed of a semiconductor device, such as a System on a Chip (SOC), and includes a display such as an LCD (Liquid Crystal Display) and memory. The display unit 25 displays images on the display based on RGB data generated by the RGB conversion unit 24.

[0037] In the video signal transmission system 100 of this embodiment, a data reordering processing unit 14 provided in the camera module 10 rearranges the Y data for the YC data and transmits an analog signal based on the rearranged YC data to the display module 20. With this configuration, it is possible to transmit the video signal in analog form while suppressing the degradation of the characteristics of the video signal. This will be explained below.

[0038] Figure 6 shows a comparison of the YC data before and after the Y data rearrangement by the data rearrangement processing unit.

[0039] In the example of YC data before rearranging the Y data shown on the left side of Figure 6, there is a large difference in brightness between adjacent Y data, resulting in a continuous, abrupt change in brightness across the entire YC data. Therefore, if the analog transmission unit 15 converts it directly into an analog signal, signal degradation is likely to occur during transmission and reception. As a result, when the display module 20 converts the YC data into video data, problems such as blurred edges and blurring at boundaries may occur.

[0040] In contrast, the YC data after rearranging the Y data shows a reduction in the number of times abrupt changes in brightness occur. This makes it less likely for signal degradation to occur when the YC data is converted to an analog signal and transmitted or received. Furthermore, it is possible to improve image quality by suppressing edge blurring and boundary blurring when the YC data is converted to video data in the display module 20.

[0041] Furthermore, in the video signal transmission system 100 of this embodiment, the data sorting processing unit 14 of the camera module 10 performs sorting of CrCb data in addition to sorting of Y data.

[0042] Figure 7 is a diagram that shows, as a comparative example, the YC data and the waveform of the resulting video change when only the Y data (i.e., only the first row in the horizontal direction) is rearranged, unlike the video signal transmission system 100 of this embodiment.

[0043] As shown in the upper and lower waveforms on the right side of Figure 7, if only the Y data is rearranged, the analog signal is transmitted from the camera module 10 to the display module 20 with the waveforms of the image changes shifted between the Y data and the CrCb data. This makes it easier for noise to occur during the transmission of the analog signal, which may lead to degradation of the video signal.

[0044] Figure 8 shows the YC data and the waveform of the resulting video change when the Y data is rearranged, as well as the Cr data and Cb data, in the video signal transmission system 100 of this embodiment.

[0045] As shown in the upper and lower waveforms on the right side of Figure 8, in addition to rearranging the Y data, the Cr data and Cb data are also rearranged. Therefore, unlike Figure 7, there is no shift in the waveform of the image change. This suppresses the generation of noise during analog signal transmission and reduces degradation of the video signal.

[0046] As described above, the video signal transmission system 100 of this embodiment makes it possible to transmit video signals in analog while suppressing degradation of image quality.

[0047] However, this disclosure is not limited to the embodiments shown above. For example, in the embodiments described above, the sorting of YC data for one line was performed in units of two, but the unit of sorting is not limited to this, and it is sufficient to perform data sorting processing for a predetermined number of units (including the entire line).

[0048] Furthermore, the YC conversion method performed by the RAW / YC conversion unit 12 is not limited to that shown in the above embodiment, and other methods may be used to perform the YC conversion.
