请问ADV7441有没有de-interlace功能?

专家好,

        我们使用7441采集D1格式视频信号时,有较严重的锯齿现象。

        请问7441本身带有de-interlace功能吗??如何消除这种现象??

以下是我的配置,请专家指正~谢谢~

 


write_add(0x0,0x5);//CVBS INPUT ON Ain6

write_add(0x03,0xc);//设置输出格式8bit、422 8位接口

write_add(0x3C,0xAD);//Setup SOG Sync level for divided down SOG

write_add(0x4,0x47);//HS,VS,F tri-stated

write_add(0x17,0x41);//Select SH1

write_add(0x1D,0x40);//外部的晶振频率=28M



write_add(0x31,0x0);//Clears NEWAV_MODE, SAV/EAV  to suit ADV video encoders

write_add(0x34,0x01);//

write_add(0x35,0x22);//

write_add(0x3A,0x07);//Power down ADC 1 & ADC2 & ADC3

write_add(0x3C,0xA8);//SOG Sync level for atenuated sync, PLL Qpump to default

write_add(0x47,0x0A);//Enable Automatic PLL_Qpump and VCO Range

write_add(0xBA,0xA0);//Enables Simultaneous Mode (certain HDMI sections kept Active)

write_add(0xF3,0x0F);//Enable Anti-Alias Filters

結果
