The display-signal processing section also converts to image data having a PAL frame rate of 25 Hz, and outputs it to a video-output interface. In other words, image data is processed at a frame rate not related to the output, and then converted to image data having a frame rate suited for the output, and output. This invention can be used in digital cameras.

Abstract: A master sheet is coated with a magnetic layer carrying magnetic signals in, for example, a spiral magnetic recording track, and is pressed into contact with a copy sheet which is also coated with a magnetic layer. A magnetic field is applied to the sheets to transfer the magnetic signals from the master sheet to the copy sheet. The copy sheet is then separated from the master sheet by air pressure, suction or mechanical means in a direction perpendicular to the sheets and subsequently fed away from the master sheet in a direction parallel to the sheets while maintained separated from the master sheet to reduce the transfer noise level to a negligible amount.
