I don't have that board so i cannot tell you much. The board has three
clocks, but i don't know either if you can use them as independent clock
sources or if there is any other constraint in their usage. I actually
remember that the DE1 board comes with sample code and it's likely that
there's a camera reference design. You might start by taking a look.

what should me clk signal. can i use the same clock which i am using
for the board.

Parallel port. You get the sampled pixels (or color components)
here. Usually pumped by the rising edge of the pixel clock.

Let me think.... :)

Pixel clock (time to read data)
> 14 MCLK1 Input Sensor 1 Master Clock
The heart of the sensor. You provide this signal.
No MCLK, no life.
> 15 LVAL1 Output Sensor 1 Line Valid
Generally, triggers the start and the end of a sampled row
When asserted, data at the parallel port is valid in sync with
the pixel clock.
> 16 FVAL1 Output Sensor 1 Frame Valid
Generally, triggers the start and the end of a whole frame
Use them to control the sensor settings by writing to
(and reading from) the internal sensor registers.

I am tring to design a video acquisition system. I am usimg the DE1
borad and the compactable TRB_DC2 camera module with it.(http://
www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=39&No=50).
The problem i am facing is on the data sheet 20 pins are assigned to
each sensor. i am a newibe to vlsi design. i am unable to distinguish
the usage of al the pins. only understood a few. can anyone help me
out by tellin whats the real functionalities of those pins
i am attaching the pin descriptions with this post
