Abstract Imaging apparatus having a video memory function includes a video memory having a plurality of read ports and a capacity of storing images in two fields or more, wherein CCD storage sensitivity enhancement means is connected to a write port; a write control circuit for storing a single-field image in each memory area provided by dividing the storage space of the video memory into a plurality of sub-spaces; a plurality of read control sections for reading a single-field image stored in each memory area; and memory control means for reading an image from the video memory by a delay amount corresponding to the timing of a synchronization signal from the CCD storage sensitivity enhancement means. This configuration allows adjustment of the delay amount and prevents an image write address from passing by an image read address so that image data given CCD storage sensitivity enhancement is processed normally.
