Abstract
Abstract An image pickup device having a solid-state image pickup element, and a memory for storing a signal read from said solid-state image pickup element, in which there are provided first and second clock pulse generation circuits for generating the clock pulse having respective predetermined frequencies, and a switch circuit for switching the clock pulse depending on whether said solid-state image pickup element is operating or not, is characterized in that when said solid-state image pickup element is operating, the processing pulse for each portion is generated based on the clock pulse generated in either one of said first and second clock pulse generation circuits, and when said solid-state image pickup element is not operating, the processing pulse for each portion is generated based on the clock pulse generated in the other clock pulse generation circuit.
