Notes:
1.
Zoom Video Port format output signal includes:
VSYNC: Vertical sync pulse.
HREF: Horizontal valid data output window.
PCLK: Pixel clock used to clock valid data and CHSYNC into Zoom V Port. Default frequency is 8.86MHz when use
17.73MHz as system clock. Rising edge of PCLK is used to clock the 16 Bit data.
Y[7:0]: 8 Bit luminance data bus.
UV[7:0]: 8 Bit chrominance data bus.
2.
All timing parameters are provided in Table 13. Zoom Video Port AC Parameters.
1.2.5
QCIF Format
A QCIF mode is available for applications where higher resolution
image capture is not required. Only half of the pixel rate is required
when programmed in this mode. Default resolution is 176 x 144
pixels and can be programmed for other resolutions. Refer to Table 7.
QCIF Digital Output Format (YUV beginning of line) and Table 8.
QCIF Digital Output Format (RGB raw data beginning of line) for
further information.
1.2.6
Video Output
The video output port of the OV6630/OV6130 image sensors
provides a number of output format/standard options to suit many
different application requirements. Table 2. Digital Output Format,
below, indicates the output formats available. These formats are user
programmable through the I
2C interface (See I2C Bus Protocol
Format).
