Effect of horizontal_mirror on Readout Order
Effect of vertical_flip on Readout Order
The sequencing of the pixel array is controlled by the x_addr_start, y_addr_start,
x_addr_end, and y_addr_end registers. The output image size is controlled by the
x_output_size and y_output_size registers.
The default settings of the sensor provide a 1600H x 1200V image. A border of up to
4 pixels on each edge can be enabled by reprogramming the x_addr_start, y_addr_start,
x_addr_end, y_addr_end, and x_output_size and y_output_size registers accordingly.
When the horizontal_mirror bit is set in the image_orientation register, the order of pixel
readout within a row is reversed, so that readout starts from x_addr_end and ends at
x_addr_start. Figure 15 shows a sequence of 6 pixels being read out with
horizontal_mirror = 0 and horizontal_mirror = 1. Changing horizontal_mirror causes the
Bayer order of the output image to change; the new Bayer order is reflected in the value
of the pixel_order register.
horizontal_mirror = 0
horizontal_mirror = 1
When the vertical_flip bit is set in the image_orientation register, the order in which
pixel rows are read out is reversed, so that row readout starts from y_addr_end and ends
at y_addr_start. Figure 16 shows a sequence of 6 rows being read out with
vertical_flip = 0 and vertical_flip = 1. Changing vertical_flip causes the Bayer order of the
output image to change; the new Bayer order is reflected in the value of the pixel_order
register.
vertical_flip = 0
vertical_flip = 1
