3-2. Bad Pixel Replacement
If the Bad Pixel Replacement Register (
bprm
) is disabled, the image sensor checks, with the preset threshold
value (
pthresh
), if the image data is less or greater than horizontally neighboring pixels in same color channel. If
satisfied, the output of the pixel is replaced by the averaged value of the neighboring two pixels. The detectable
defective pixels are rare and the bad pixel replacement action can remove the defective image effectively. But it
reduces the line resolution in the horizontal direction.

C Serial Interface
I
2
C is an industry standard serial interface. I
2
C contains a serial two-wire half duplex interface that features bi-
directional operation, master or slave mode. The general
SDA
and
SCL
are the bi-directional data and clock pins,
respectively. These pins are open-drain type ports and will require a pull-up resistor to VDD. The image sensor
operates in the salve mode only and the
SCL
is input only. I
2
C bus interface is composed of following parts :
START signal, 7-bit slave device address (0010001b) transmission followed by a read/write bit, an
acknowledgement signal from the slave, 8-bit data transfer followed by an acknowledgement signal and STOP
signal. The
SDA
bus line may only be changed while
SCL
is low. The data on the
SDA
bus line is valid on the
high-to-low transition of
SCL
.
