Hardware connection
Module pin out #15 (SPI_MCLK) must be supplied with 24 MHz clock. Pin out for #4(SPI_Data), #5(SPI_CLK) and #16(SPI_
Csn) are SPI output signal for imaging data.
Skip mode
1st, 3rd, 5th….pixels information are used for image formation; the information of 2nd, 4th, 6th….pixel are not used for
image formation.
Average Mode
1st and 2nd pixels are averaged as 1-pixel information. Similarly, 3rd and 4th pixels are averaged as 1-pixel information.
Hence a total of 60 × 60 pixels information are averaged to become 30 × 30 pixels information.
Crop Mode
60 × 60 pixels are cropped with the center 30 × 30 pixels being used for image formation.
