SUMMARY
Image sensors can capture two-dimensional distribution of physical quantities in the real world. There are various types of image sensors depending on the information to be acquired, such as optical image sensors that detect the intensity of light, and ToF image sensors that detect distance based on time differences. By measuring the capacitance, it is possible to detect the presence or absence of an object near the sensor and the distance between the object and the sensor. A proximity capacitance image sensor, which consists of an array of capacitance sensors, can detect and . . .
