The fill factor of an image sensor array is the ratio of a pixel's light sensitive area to its total area. For pixels without microlenses, the fill factor is the ratio of photodiode area to total pixel area,[1] but the use of microlenses increases the effective fill factor, often to nearly 100%, by converging light from the whole pixel area into the photodiode.[2]

Another case that reduces the fill factor of an image is to add additional memory beside each pixel, so as to achieve a global shutter on CMOS sensors.[3]

图像传感器阵列的填充系数是像素的光敏面积与其总面积的比率。对于没有微透镜的像素，填充系数是光电二极管面积与总像素面积的比值，[1]但微透镜的使用增加了有效填充系数，通常接近100%，通过将光从整个像素区域聚集到光电二极管[2]。
另一种减少图像填充因子的情况是在每个像素旁边添加额外的内存，从而实现CMOS传感器的全局快门。[3]
