DCG Dual Conversion Gain(双转换增益) 通过调整不同的阱容获得不同增益的曝光值,即为双转换增益技术。即像素拥有两个不同的FWC,在小FWC时,底噪较小,对应着高增益;相反,在大FWC时,底噪大,对应着低增益。
DGA 双原生ISO技术(Dual Gain Amplifier) Dual Gain Amplifier该技术是在电路中提供了两条电路,两条电路的增益大小的PGA不同,可以输出两个不同增益的信号。改变了模拟增益,相当于改变了ISO,因此也称为双原生ISO技术
DOL-HDR CMOS输出三张不同时间的图像,在经过ISP多帧融合图像处理后生成HDR图像
DOL2 sensor完成一帧曝光,sensor生成2幅图像,图像传输到ISP,ISP再将两幅图像合成为一帧图像(两帧融合)
DOL3 sensor完成一帧曝光,sensor生成3幅图像,图像传输到ISP,ISP再将三幅图像合成为一帧图像(三帧融合)
izoom 普通izoom又称izoom 1dol,其实两者的寄存器是一样的,之所以专门弄个izoom 1dol,是因为需要做seamless切换,看transitionGroups就知道了
izoom lbmf izoom lbmf(又称izoom 2dol),即同帧输出长短曝的izoom图像
