About the Kit
The TRDB_D5M Kit provides everything you need to develop a 5 Mega Pixel Digital Camera on the Altera DE4 / DE2_115 / DE2-70 / DE2 / DE1 boards. The kit contains hardware design (in Verilog) and software to load the picture taken into a PC and save it as a BMP or JPG file (DE2-70 only). The Getting Started User Guide enables users to exercise the digital camera functions. This chapter provides users key information about the kit.

1. High frame rate
2. Superior low-light performance
3. Low dark current
4. Global reset release, which starts the exposure of all rows simultaneously
5. Bulb exposure mode, for arbitrary exposure times
6. Snapshot mode to take frames on demand
7. Horizontal and vertical mirror image
8. Column and row skip modes to reduce image size without reducing field-of-view
9. Column and row binning modes to improve image quality when resizing
10. Simple two-wire serial interface
11. Programmable controls: gain, frame rate, frame size, exposure
12. Automatic black level calibration
13. On-chip PLL

Digital Camera Design Demonstration
This chapter illustrates how to exercise the digital camera reference design provided with the kit. Users can follow the instructions in this chapter to build a 5 Mega Pixel camera using their DE4 / DE2_115 / DE2-70 / DE2 / DE1 in minutes.

DDeemmoonnssttrraattiioonn SSeettuupp
The image raw data is sent from D5M to the DE4 / DE2_115 /DE2-70 / DE2 / DE1 board. The FPGA on the DE4 / DE2_115 /DE2-70 / DE2 / DE1 board is handling image processing part and converts the data to RGB format to display on the DVI / VGA monitor. For DE2-70, the image captured at SDRAM can be taken at anytime (snapshot) and uploaded to a PC as a BMP/JPG file.

Directory: Demonstration / DE4_230/530_D5M_DVI FPGA Bitstream Used: DE4_230/530_ D5M_DVI.sof
1. Ensure the connection is made correctly as shown in Figure 3-1. Make
sure the D5M is connected to JP4 (GPIO 1) and DVI daughter card is connected to J20 (HSMC PORT A) of the DE4 board with two THCB-HMF2 interface cards which are bundled in the DE4 kit.
2. Insert the DDR2 memory card into J9 (DDR2 SO-DIMM-1).
3. Connect the DVI TX output of the DVI daughter card to a DVI monitor.
4. Copy the directory DE4_230/530_D5M_VGA from D5M System CD-ROM to the host computer.
5. Download the bitstream (DE4_230/530_D5M_DVI.sof) to the DE4 board.

7. User can use the SW[0] to set the DVI display mode. When SW [0] is
set to Off, the DVI will display whatever the camera captures. when
On, the DVI will display color pattern.
8. Press BUTTON [2] to take a shot of the photo; you can press
BUTTON [3] again to switch back to FREE RUN mode and you should
be able to see whatever the camera captures on the VGA display..
9. User can use the SLIDE_SW [0] with BUTTON [1] to set the exposure
time for brightness adjustment of the image captured. When
SLIDE_SW [0] is set to Off, the brightness of image will be increased
as BUTTON [1] is pressed longer. If SLIDE_SW [0] is set to On, the
brightness of image will be decreased as BUTTON [1] is pressed
shorter.
10. Set the SLIDE_SW [1] to On (upper position), the captured image
will be enlarged with BUTTON [0] and BUTTON [3] pressed in order.
11. Table 3-1 summarizes the functional keys of the digital camera.

12. User can revise the header file "vpg.h" in the project to select the
system resolution between SXGA@1280*1024 and VGA@640*480
(note*).
13. After revision, regenerate the project and repeat above steps.
Note: users should revise the parameter ‘PORT_SIZE_BYTES’ of the
DDR2_ODIMM_Read/Write_Port modules in SOPC Builder under each resolution (640*480*4, 1280*1024*4 respectively) .
