AP0101 HDR: Image Signal Processor (ISP)
General Description
General Description
Aptina's AP0101 is a high-performance, ultra-low power in-line, digital image processor
optimized for use with HDR (High Dynamic Range) sensors. The AP0101 provides full
auto-functions support (AWB, AE, AFD)and ALTM (Adaptive Local Tone Mapping) to
enhance HDR images and advanced noise reduction which enables excellent low-light
performance.
Functional Overview
Figure 1 shows the typical configuration of the AP0101 in a camera system. On the host
side, a two-wire serial interface is used to control the operation of the AP0101, and image
data is transferred using the parallel bus between the AP0101 and the host. The AP0101
interface to the sensor also uses a parallel interface.

System Interfaces
Figure 2 on page 8 shows typical AP0101 device connections.
All power supply rails must be decoupled from ground using capacitors as close as
possible to the package.
The AP0101 signals to the sensor and host interfaces can be a different supply voltage
levels to optimize power consumption and maximize flexibility. Table 1 on page 9
provides the signal descriptions for the AP0101.

AP0101 HDR: Image Signal Processor (ISP)
Image Flow Processor
Color Interpolation
In the raw data stream fed by the sensor core to the IFP, each pixel is represented by a 20-
or 12-bit integer number, which can be considered proportional to the pixel's response
to a one-color light stimulus, red, green, or blue, depending on the pixel's position under
the color filter array. Initial data processing steps, up to and including the defect correc-
tion, preserve the one-color-per-pixel nature of the data stream, but after ALTM it must
be converted to a three-colors-per-pixel stream appropriate for standard color
processing. The conversion is done by an edge-sensitive color interpolation module.
The module pads the incomplete color information available for each pixel with infor-
mation extracted from an appropriate set of neighboring pixels. The algorithm used to
select this set and extract the information seeks the best compromise between
preserving edges and filtering out high frequency noise in flat field areas. The edge
threshold can be set through register settings.
Color Correction and Aperture Correction
To achieve good color fidelity of the IFP output, interpolated RGB values of all pixels are
subjected to color correction. The IFP multiplies each vector of three pixel colors by a 3 x
3 color correction matrix. The three components of the resulting color vector are all
sums of three 10-bit numbers. The color correction matrix can be either programmed by
the user or automatically selected by the auto white balance (AWB) algorithm imple-
mented in the IFP. Color correction should ideally produce output colors that are
corrected for the spectral sensitivity and color crosstalk characteristics of the image
sensor. The optimal values of the color correction matrix elements depend on those
sensor characteristics and on the spectrum of light incident on the sensor. The color
correction variables can be adjusted through register settings.
To increase image sharpness, a programmable 2D aperture correction (sharpening filter)
is applied to color-corrected image data. The gain and threshold for 2D correction can
be defined through register settings.
Also included in this block is a Fade-to Black curve, which sets all knee points to zero and
causes the image to go black in extreme low light conditions.
Gamma Correction
The gamma correction curve is implemented as a piecewise linear function with 33
points, taking 12-bit arguments and mapping them to 10-bit output. The abscissas of the
points can be fixed or bottom weighted.
The 10-bit ordinates are programmable through variables.
The AP0101 has the ability to calculate the 33 point curves based on a small number of
variable inputs from the host, another option is for the host to program one or both of
the 33 point curves.
