Abstract:
1. An image pickup apparatus comprising: an image pickup unit which captures an image and outputs an analog image signal; a conversion unit which converts the analog image signal into a digital image signal; a synchronization signal generation unit which generates a synchronization signal to be supplied to the image pickup unit and to the conversion unit, and which supplies the synchronization signal to the image pickup unit; and an adjustment unit which adjusts a timing at which the synchronization signal generated by the synchronization signal generation unit is supplied to the conversion unit, and which supplies the synchronization signal to the conversion unit at the adjusted timing, wherein the adjustment unit is disposed in a position such that the adjustment unit is substantially affected by a self-heating of the image pickup unit, wherein a delay amount of the analog image signal of the image pickup unit fluctuates in accordance with a fluctuation of a heat affecting the image pickup unit; and wherein a delay amount of the synchronization signal of the adjustment unit fluctuates in accordance with a fluctuation of a heat affecting the adjustment unit.
