摘要：
A video signal processing apparatus including an input unit for inputting a video signal, a detecting unit for detecting an aspect ratio of the video signal inputted to the input unit, a holding unit for holding aspect information representing the aspect ratio detected by the detecting unit, an abnormal state detecting unit for detecting an abnormal state of the video signal inputted to the input unit, and an output unit for selectively outputting aspect information outputted from the aspect ratio detecting unit and the aspect information held by the holding unit, in accordance with an output of the abnormal state detecting unit.
