ELECTRONIC SYTEM AND IMAGE SYSTEM FOR MEASURING PARTICULATE MATTER AND METHOD FOR MEASURING PARTICULATE MATTER

摘要

An electronic system according to an embodiment of the present invention includes a lighting, a sensor, and a processor. Lighting outputs light. The sensor includes a pixel array that generates an analog signal based on scattered light according to the output light, and a conversion circuit that converts the analog signal into digital signals respectively corresponding to the gain values based on the gain values. The processor counts the number of values of digital signals that are greater than or equal to a threshold value, and calculates the concentration of fine dust having a target size range based on a change in the counted number according to a change in gain values.
