IMAGE PROCESSING FUNCTIONS
Function
Description
Remarks
Defect detection and
correction
If enabled, the function detects the defective pixel by
comparing its level with horizontally neighboring pixels, and
replaces it with the average value of neighboring pixels.
De-mosaic
The sensor produces one color component from a pixel
according to Bayer color filter array. The de-mosaic function
performs color interpolation to produce all three-color
components at each pixel location.
Color correction
The spectral response of image sensor is different from that
of human eye. To match the spectral response, the sensor
output components are pivoted by user programmable 3X3
matrix production.
Gamma correction
Gamma correction translating the linear response of the
sensor into the non-linear characteristics of the display. Non-
linear conversion requires a piecewise linear approximation
method based on user programmable lookup table.
Horizontal mirror
The output image can be mirrored in horizontal direction.
Vertical mirror
The output image can be mirrored in vertical direction.
Edge enhancement
Enhancing the edge component provides a clear output
image. The edge enhancement function is performed through
horizontal and vertical edge detecting and enhancing.
Auto exposure
According to the incident light level, the auto exposure
function controls the sensor gain and effective integration time
Auto white balance
The auto white balance function adjusts the gain of the
sensor’s red and blue channels relative to the green channel,
and compensates the spectral unbalancing of the light source.
Setting the control registers can change the sensing area used
in the AWB algorithm.
Output format conversion
4 types of output format are available.
(CCIR656 format, CCIR601 format, RGB format and sensor
raw image output format)
Sub-sampling Control
The user can read out the pixel data in sub-sampling rate in
both horizontal and vertical direction. Sub-sampling can be
done in two rates: full and 1/2. The user controls the sub-
sampling using the Sub-sampling Control Registers,
subsr
and
subsc
. The sub-sampling is performed only in the Bayer
space.
