Imaging device including timing generator that generates vertical synchronization signal after number of lines of valid image signal reaches number of valid lines of vertical scanning period

摘要

A display control device controls an image displayed on a display unit based on an image signal synchronized with a horizontal synchronization signal and a control signal indicating that the image signal is valid or invalid. The device includes: an input unit that inputs a valid image signal based on the control signal; an output unit that outputs the input valid image signal to the display unit; and a comparison unit that compares the number of lines of which the image signal becomes valid with the number of valid lines of one frame.
