A 4/3-type CCD is used for image capture. Offering 4 to 5 times the imaging area of the 1/1.8-type and 2/3-type sensors used in most compact digital cameras, the E-1's sensor delivers the image quality that professional users demand. In addition, the full-frame CCD delivers richer gradations than an interline CCD.

| A CCD converts the light sensed by its photodiode into electronic signals, and sends them to image memory. The CCD has a data-transfer channel for sending these signals. The widely used interline method places this data-transfer channel between adjacent pixels. Conversely, full-frame method provides a data-transfer channel for each pixel. |

| The full-frame method allows each photodiode to be larger than with the interlined method, even with the same pixel interval. This provides a superb range of expression, even in dimly lit places. Full-frame CCDs also eliminate the need for a data-transfer channel separate from the photodiodes. This allows for more space to store electric charge emitted by the photodiodes than with an interline CCD, providing high fidelity, even in brightly lit places. |
