This imaging apparatus includes: an imaging element for a color; a lens that forms an image of image light on an imaging surface of the imaging element; an A/D converter that converts an analog signal for each color, which is output by the imaging element, into a digital signal to generate raw data; a transmission processor that generates an IP packet storing the raw data generated by the A/D converter; and a network interface that transmits the generated IP packet to a server capable of performing development processing of the raw data, through a network.
