PRODUCT INFORMATION
PRODUCT SUMMARY
KS7333 is a product used in video camera systems, such as camcorders and surveillance camera systems that
use charge coupled devices (CCD). It takes the CCD input as digital data and performs 3-D interpolation, image
scaling, and minimization of resolution potential using horizontal/vertical line interpolation on the data. In
addition, it detects the amount of movement caused by shaking while held by the hands through 1-D projection
pattern matching and corrects for it. It also has the 1/16 picture-in-picture function as well as the digital effect
function that uses field memory.

SYSTEM CONFIGURATION & OPERATION DESCRIPTION
MOTION DETECTION BLOCK
The motion detection block can be divided into the horizontal motion vector detection block and the vertical
motion vector detection block. Its input is the upper 4 bits of the 8-bit luminance signal which is the LPF-handled
part of the 10-bit S1S2 format signal. The block uses the difference between the previous image and the current
image to find the motion vector. To find the motion vector, the current image's luminance value during the input
image's active period must be projected in both horizontal and vertical direction to the current line memory, and
put through correlation matching with the value stored in the previous line memory. In this process, the location
with the smallest correlation error becomes the motion vector. The search for the motion vector is limited to ±64
in the horizontal direction, and ±23 in the vertical direction.
To reduce the calculation amount and the time spent in operation, the coarse-to-fine correlation operation is
carried out within the search area. The correlation operation is put into effect within the vertical blank section, and
the motion vector that is finally output has the horizontal value of 7 bits and vertical value of 6 bits.

ISF BLOCK
The ISF block accumulates the motion vectors (VX, VY) between the image fields to first calculate the integration
value (GX, GY), which is the actual correction value used. If you use the motion vector's integration value, the
motion is corrected flawlessly. However, if the camera user's deliberate movements (panning) are also corrected,
a memory should have compensation limit in image.
To correct such a problem, the accumulated image movement is divided into high frequency and low frequency
components, and only the high frequency components are corrected. To effectively divide these high frequency
components, IIR filtering is independently carried out horizontally and vertically.
At this time, The feedback coefficient of the filter can be selected in MICOM.

DIGITAL ZOOM BLOCK
This block receives the AD-converted S1S2 format image as its input, puts it through DPCM compression, and
uses the external SDRAM to store the compressed image signal in real time, 1 field at a time. It then restores the
stored image signal and magnifies it to maximum 255 times the original, using the zoom coefficient controlled by
MICOM. The magnified image is divided into Y/C using the LPF and goes through the 256-step linear
interpolation.
The aperture feature precedes the linear interpolation, and the interpolated image signal is output through the
temporal IIR filter. At the same time, the output is stored in 2 fields of the SDRAM.

•

•
Color edge suppression (5 tabs)
DCPM compression/restoration for efficient memory use
It's not matched between SDRAM data width (16 bits) for store and inputted image signal data width-10 bit.
Therefore, in case of storing inputted image, itself (10 bit) data, it's inefficient. To solve that, it compresses 20%
from 10 bit to 8 bit with that inputted image data width by adopting DPCM compression technology.
Y/C separation through LPF
Restored DPCM data which is S1 S2 format needs to separate Y/C for image processing, at this time, Y signal is
separated by LPF and C signal is separated by HPF.
Aperture feature for Y signals
This system is 4 line processing to vertical direction. Aperture to vertical direction decides to considering by
impulse response with using the spline method (refer the micom mode operation part). Horizontal aperture is
obtained by adjusting the gain with edge information by adopting 5 tabs.

PICTURE-IN-PICTURE BLOCK
This block uses the AD-converted S1S2 format image as an 8-bit input, divides it into Y/C, and finds the typical
value for each Y/C through low pass filtering. The filtered Y/C signal is synthesized into S1S2 format and stored
in real time, 2 fields at a time, using the SDRAM. The compression-stored image signal is overlayed on the real
image using the location value which comes from the MICOM control value.

TEMPORAL IIR FILTER BLOCK
This block receives the image's output signal, stores it in SDRAM through DPCM compression, reads the stored
signal in real time, then restores it. The restored image signal is divided into Y/C, and it goes through the 255step linear interpolation to be synthesized into S1S2 format. This synthesized image signal and the zoom output
are
3-D interpolated using the sub-pixel information output by the motion detection and the zoom.

This block generates the image's horizontal/vertical count information using the sync signal from the Timing
Generator (TG) as the standard. It uses DVC, HIGH, PAL, and AP_ADJ (start point adjustment) from the system

generate HD, VD, and FLD (FIELD) signals.

SCLK:
System micom's main clock, whose cycle corresponds to the timing diagram.
SMI:
Input through triggering at the SCLK's negative edge and valid only when SCSN is low. The first bit can
be either "H' (Read Mode) or "L" (Read/Write mode) and the next 7 bits specify the address of the
register to be controlled. Starting from the start address, the address reduces by one every time an 8bit
data arrives.
Data is valid only when it becomes an 8bit data. However, if SCSN becomes high before an 8 bit data is
sent, that data becomes invalid.
SCSN: Data enable signal which is low active.
SMO:
Output through triggering at the SCLK's negative edge and valid only when SCSN is low.

OVERLAY
0000_0010
OVERLAY: Feed back image(TIIR filter) boundary adjust
To perform the TIIR filtering, the feedback image and the present image must match precisely.
Therefore, to compensate for the visual movement between fields, the feedback image is
compensated based on the detected motion vector. Garbage data, the image boundary section, is
not compensated during TIIR filtering, so boundary detection is required for processing at a valid
area.
