如何使用spartan3E入门套件显示图像

我认为你需要将彩色图像转换成二进制图像。
将每个8位R，G，B转换为1位二进制图像。
希望它会有所帮助

I think you need to convert color image into binary image. convert each 8 bit R, G, B into 1 bit binary image.

Hope it will helpThanks and Regards

该板仅支持3位显示颜色代码。
您需要将24位彩色图像转换为3种双色。
每个位代表一种颜色。
要从8位转换二进制，您可以在128灰度级上获取阈值。
任何超过128位的值都可以表示'1'，否则'0'

以下为原文

This board only support 3-Bit Display Color Codes. You need to convert your 24 bit color image into 3 bi colors. Each bit represent one color. To convert the binary from 8 bit you can take threshold on 128 gray level . Any value above 128 bit you can represent '1' and else '0'Thanks and Regards

先生，
RGB3 = uint8（IMG> 128）;
是否是在matlab中将24位彩色图像转换为3位颜色的正确方法。
或建议我一些相关的链接



以下为原文

Sir,
 
RGB3=uint8(IMG > 128);
 
 is it correct way to convert 24 bit color image into 3 bit color in matlab.
 or suggest me some links regarding that

您正在使用哪种语言进行申请。
在VHDL中，RGB应该是23到0，G = 23到16R = 15到8 B = 7到0G_out ='1'当G> 128时0';
当R> 128时，R_out ='1'，否则为0';
当B> 128时，B_out ='1'0';
G_out，R_out，B_out将位于顶层，并为ucf中的这些端口分配正确的引脚

以下为原文

which language you are using for your application.

RGB  should be 23 down to 0 in VHDL

G = 23 down to 16
R = 15 down to 8
B= 7 down to 0

G_out = '1' when G >128 else
               0';

R_out = '1' when R >128 else
               0';
B_out = '1' when B >128 else
               0';

G_out, R_out, B_out  will be on top level and assign correct pin for these ports in ucf

Thanks and Regards

好的，谢谢你，我会尝试使用这个。
谢谢。

ok thank you i will try using this. thank you.

先生，我试过阈值，但没有显示图像。只有屏幕变成深灰色。



以下为原文

sir i tried thresholding but no image is displaying.Only the screen becomes dark gray .

你好
您可以尝试实现更小的尺寸，但由于这些设备没有DSP模块和低密度设备，因此不适合较大的视频尺寸或视频应用。
这些设备不支持Xilinx视频IP。

以下为原文

Hi
 
You can try implementing for smaller sizes but as these devices doesn't have DSP blocks and low density devices these are not suitable for larger video sizes or video applications.
 
The Xilinx Video IP's are not supported for these devieces.

Satish
