| Zusammenfassung: | An image sensor includes a voltage controlled oscillator and an evaluation circuit. The voltage controlled oscillator outputs a periodic signal, wherein a frequency of the periodic signal is a function of an input voltage signal at an oscillator input of the voltage controlled oscillator. The input voltage signal is derived from an internal constant voltage signal of the image sensor. The evaluation circuit outputs a notification signal when a frequency of the periodic signal fulfills a predetermined condition. |
