I am trying to make a project wherein I will capture an image thru DE1 D5M camera module and then convert the image to grayscale then show the ouptut thru VGA in a monitor. How can I do this? I mean, can I store the converted image to SDRAM then from there can I output it to VGA? Help please. I'm not familiar how SDRAM works in the DE1.

That is a feasible way of doing. You may want to have a look at the VIP-Suite[1] (Video-Image-Processing-Suite) for first try. 

 

If you have precise questions do not hesitate to ask.

I tired to edit the DE1_D5M code given by altera. From there, I wanted to convert the RGB image to grayscale from a separate module and then output it to VGA.  

 

Part of my top module is here: 

 

assign DISP_R = SW ? GrayscaleR : VGA_out_R; assign DISP_G = SW ? GrayscaleG : VGA_out_G; assign DISP_B = SW ? GrayscaleB : VGA_out_B; // RGB assign VGA_out_R = Read_DATA2; assign VGA_out_G = {Read_DATA1,Read_DATA2}; assign VGA_out_B = Read_DATA1; // Gray assign GrayscaleR = VGA_out_G; assign GrayscaleG = VGA_out_G; assign GrayscaleB = VGA_out_G; assign VGA_CTRL_CLK= rClk; assign VGA_CLK = ~rClk; always@(posedge CLOCK_50) rClk <= rClk+1; wire oVGA_R; wire oVGA_G; wire oVGA_B; assign VGA_R = oVGA_R; assign VGA_G = oVGA_G; assign VGA_B = oVGA_B; always@(posedge CCD_PIXCLK) begin rCCD_DATA <= CCD_DATA; rCCD_LVAL <= CCD_LVAL; rCCD_FVAL <= CCD_FVAL; end VGA_Controller u1 ( // Host Side .oRequest(Read), .iRed(DISP_R), .iGreen(DISP_G, .iBlue(DISP_B), // VGA Side .oVGA_R(VGA_R), .oVGA_G(VGA_G), .oVGA_B(VGA_B), .oVGA_H_SYNC(VGA_HS), .oVGA_V_SYNC(VGA_VS), // Control Signal .iCLK(VGA_CTRL_CLK), .iRST_N(DLY_RST_2) &nbsp;);

and what is your concrete problem within that task?

I want to clarify that in the VGA_Controller macrofunction, the output that will be shown will be based on the VGA side?
