Pixel Readout (Column Bin 2X, Row Bin 2X) X incrementing X incrementing Mirror Column Mirror Image By setting R0x20[14] = 1, the readout order of the columns is reversed, as shown in Figure 21. The starting color, thus Bayer pattern, is preserved when mirroring the columns. Figure 21.

The starting color, thus Bayer pattern, is preserved when mirroring the rows. Figure 22. Six Rows in Normal and Row Mirror Readout Modes DOUT[11:0] FRAME_VALID Normal readout Row0 (11:0) Row1 (11:0) Row2 (11:0) Row3 (11:0) Row4 (11:0) Row5 (11:0) DOUT[11:0] Reverse readout Row4 (11:0) Row5 (11:0) Row3 (11:0) Row2 (11:0) Row1 (11:0) Row0 (11:0) By default, active pixels in the resulting image are output in row-major order (an entire row is output before the next row is begun), from lowest row/column number to highest. If desired, the output (and sampling) order of the rows and columns can be reversed. This affects only pixels in the active region defined above, not any pixels read out as dark rows or dark columns. When the readout direction is reversed, the color order is reversed as well (red, green, red, and so on, instead of green, red, green, and so on, for example). |
