Webto increase the sensor ﬁll factor, e.g., by arranging an array of microlenses on the sensor array [6,7]. However, due to the physical limitation in practical development and manufacturing of digital cameras, the ﬁll factor of an image sensor cannot be 100% [2]. WebOperating on the photoelectric effect, image sensors convert photons into electrical charge. Unlike CCD sensors (Charge-Coupled Device), CMOS sensors (Complementary Metal-Oxide Semiconductor) convert charge into voltage straight in the pixels. Voltage amplification and quantization create the output digital value.

What Does Fill Factor Mean When Talking About Photography?

WebPixel Size & Fill Factor The fill factor (see figure 4) of a pixel describes the ratio of light sensitive area versus total area of a pixel, since a part of the area of an image sensor pixel is always used for transistors, wiring, capacitors or registers, which be-long to the structure of the pixel of the corresponding image sensor (CCD, CMOS ... WebHowever, major improvements can still be made. For example, in the biotin-streptavidin experiments, the spots only occupied the 5% of the image (that is, 271,286 out of the available 5,013,504 pixels on the sensor). The ratio between active and inactive pixels on an image is defined as the fill factor (FF).
