PRODUCT BRIEF
Overview
Zoran's COACH-LC is the third generation Camera On
A CHip (COACH) digital still camera processor,
following the COACH and COACH-XL processors.
COACH-LC is highly compatible with COACH and
COACH-XL. All processors share the same device
drivers and hardware interfaces. User interface software
can also be reused across all three processors.
COACH-LC is a complete solution for digital still camera
designs. It includes all required hardware and microcode
to support: progressive and interlaced CCD sensors,
CMOS
Features
§
Direct glueless interface to industry standard
CCD sensors from Sony, Sharp, and Matsushita
(progressive and interlaced), and to several
CMOS sensors.
§
Supports image resolutions of up to 2.3
Megapixels.
§
Advanced CCD signal processing:
o
Quantization noise shaping
o
Color de-mosaic with aliasing reduction
o
Color space conversion
o
Image scaler
o
Automatic White Balance (AWB)
o
Automatic Exposure (AE)
o
CCD noise suppression
o
Contrast enhancement
o
Edge enhancement
§
Support for flash strobe light control, including
red-eye reduction.
§
Direct interface to resident flash memory and/or
removable flash memory cards: CompactFlash
(CF) and SmartMedia (SSFDC) and others.
§
Supports 16, 32, 64, 128Mbit SDRAM frame
buffers (depending on the sensor resolutions).
§
Serial Communication Port for RS-232 and IrDA
interface.
§
USB interface, including on-chip USB line
drivers.
§
Real-time JPEG compression with advanced bit
rate control ensures superior visual quality for
the required number of stored images.
COACH-LC
sensors, View-LCD display, Eye-LCD display, TV output,
Flash Memory, USB interface, RS232 interface and
stereo audio recording/playback.
COACH-LC is a cost effective, yet highly powerful
digital still camera processor. Its architecture is flexible
enough to support a wide range of camera designs, from
low cost, low-resolution cameras up to high performance
professional cameras with real-time high resolution
image processing. User Interface software can be
implemented within the COACH-LC (reducing the
overall camera cost) or via an external micro-controller.
The COACH-LC comes with a complete development
package that includes a set of software tools, PC drivers
and a reference design platform.
Camera System Block Diagram
§
Capture sequence of still images at 15 images
per second.
§
Movie (AVI) capture and playback to the Flash
card
§
Video Capture Mode - capture CIF at 30 frames
per second or VGA at 15 frames per second
real-time video (MJPEG compressed) to a PC
via USB.
§
Audio codec support, allows for MP3 stereo
playback and audio annotation of pictures.
§
User interface implemented within the COACH-
LC, no need for an additional microcontroller.
§
Analog and digital LCD, direct interface to Eye-
LCD.
§
NTSC/PAL encoder provides direct analog
output to a TV monitor.
§

and audio file format
§
Font-based and graphics-based OSD (On
Screen Display) engines for displaying user-
interface messages, menus and icons on the
LCD/TV.
§
Image enhancement & processing algorithms,
e.g., image sharpening, image smoothing, and
superposition of images for improved viewing
and printing quality.
§
Programmable DSP engine ensures seamless
upgrades through downloadable firmware.
§
Advanced power management.
§
256-pin MQFP & 280-pin BGA packages.
