LVCOMS Digital Video

LVCMOS digital video includes 1 Clock signal (Clock), 1 Line_Valid signal and 1 valid frame signal(Frame_Valid), and 14 data signals (dv0-dv13).Pixel data bits are divided into 14 bit and 8 bit, when the user chooses to lose. When RAW data or temperature (TMP) data is selected, there is all together 14-bit data, namely DV[13:0], where DV0 is LSB and DV13 is the MSB. When the user selects the data after the output image processing (DRC), there is all together 8-bit data, namely DV[7:0], where DV0 is LSB and DV7 is the MSB. LVCMOS digital video can be turned on or off with control commands. While the LVCMOS digital video is turned on, you can choose to output raw data (ORG) or non-uniform correction (NUC) data, or image processing (DRC) data.
When DRC data is selected, the thermal camera module does not support the function of digital zoom and temperature information display.

Note:

1. Clock rising edge sampling is recommended for DV.
2. Line_Valid and Frame_Valid are both high-level valid.
3. after Line_Valid is valid, it lasts for n Clock, which corresponds to the data of the first column to the last column of the row in turn.

LVDS Digital Video

LVDS digital video includes 1 clock signal (LVDS_CLK) and 4 data signals (LVDS_DATA1, LVDS_DATA2, LVDS_DATA3, and LVDS_DATA4), which can be easily analyzed by domestic mainstream video coding & decoding chip.
LVDS digital video can be turned on or off with control commands. In the open state, choose to output raw data (ORG) or non-uniformity correction (NUC) data, or image processing (DRC) data.
When choosing to use image processing (DRC) data, the core component does not support the function of electronic zoom and temperature information display.

BT.1120 Digital Video

Bt.1120 digital video is the line-by-line output signal, including the Clock signal (Clock), frame effective signal, line effective signal, 16 data signals (dv0-dv15). FIG. 5 sequence diagram takes the n×m array as an example:
When choosing to use bt.1120 digital video, the thermal camera component does not support the electronic zoom, temperature information display function.

BT.656 Digital Video
Bt.656 digital video, including 1 Clock signal (Clock) and 8 data signals (DV0-DV7).
BT.656 digital video supports all functions of the thermal camera module (see table 1 for image adjustment and temperature measurement), including brightness/contrast adjustment, polarity selection, color Palette selection, reticle control, digital zoom and image flip functions, and only supports output image processing (DRC) data.

CDS_2 digital video (only available for T-series)
CDS_2 digital video contains 1 Clock signal (Clock), 1 frame valid signal (Vsync), 1 line valid signal (Hsync), and 16 DATA signals (DATA).The video data consists of two parts, the first half of each row of data is divided into an image, which conforms to the YUV422 format. The high 8 bits is the brightness component, the low 8 bits is the chroma component, and the image supports pseudo-color mapping. The second half of each row is divided into temperature data. The actual significant bit is 14 bits, and the higher two bits complement 0.

Remark:

1. The output image data format is YUV, the high 8bit is Y, the low 8bit is UV.
2. “T” stands for temperature data (effective data bits are 14 bits lower, two bits higher complement 0), “TH” stands for 8 bits higher, and “TL” stands for 8 bits lower.
3. External synchronization signal mode is adopted. “Vsync” represents the frame synchronization signal and “Hsync” represents row synchronization signal.
4. The output data of each row is 2 times of the array N, such as a thermal camera module with array of 640*512, each row contains 640*2=1280 clock cycles (N = 640), and each frame contains 512 rows (M=512).

MIPI Protocol
MIPI digital video includes 1 pair of source-synchronized differential clocks (MIPI_CLK+,MIPI_CLK-), and 4 pairs of differential data lines (MIPI_DATA0+,MIPI_DATA0-,MIPI_DATA1+,MIPI_DATA1-,MIPI_DATA2+, MIPI_DATA2-, MIPI_DATA3+, MIPI_DATA3-).
The clock signal enters the high-speed mode at the beginning of each frame and exits it at the end of the frame. The inter-frame is in the low-power mode (the data and clock lines are both at a 1.2V high level). The data line sends a packet header at the beginning of each frame, and a packet footer at the end of the frame. There are 192 data packets between the packet header and the packet footer, and each long packet data contains one line of valid data. The data format and electrical characteristics comply with the CSI-2 standard and D-PHY protocols with an output clock frequency 200MHz and 4lane data lines.

Imaging Modules
After the module is connected to power, it will start to output MIPI digital video and data of 640*512 array. The data format can be set to RAW8, RAW14, and YVU422 through the refreshing program, and the settings are as follows:

The data format is the standard MIPI CSI-2 protocol, as shown below.

1. RAW8
2. RAW14
3. YUV422

Thermographic Module
After the module is connected to power, it will start to output MIPI digital video and data of 1280*512 array. The data format can be set to YVU422 format through the refresh program. The module settings are as follows:

The output of YUV422 is 1280*512 array data. The first 640 pixels of line valid data are image data, which can be output directly in YVU422 format. The last 640 pixels of line valid data are temperature data, which requires that the UYVY backend of 2 pixels is spliced into two 16-bit temperature data by itself, with the more significant byte first. The data format of one line is shown in the figure below.
