352/spl 倍/288 像素阵列通过合并顺序线性和对数图像实现 >120 dB 动态范围。校准用于匹配偏移和增益。 7 晶体管像素采用 0.18 /spl mu/m 1P4M CMOS 工艺构建。
A 352/spl times/288 pixel array achieves >120 dB dynamic range through merging sequential linear and logarithmic images. Calibration is used to match offset and gain. A 7-transistor pixel is built in a 0.18 /spl mu/m 1P4M CMOS process.
