Abstract: The object of the present invention is to convert a signal from an arbitrary equipment into a signal at a data rate for used in a device. A semiconductor memory (7) is controlled by a control signal from a memory control section (8), thereby repeatedly reproducing recorded still image signals each corresponding to one frame. If a reproduction signal has a data rate of 4 : 4 : 4, the reproduction signal is supplied to a rate conversion circuit (9) for converting the data rate into 4 : 2 : 2 or 4 : 1 : 1. A digital video signal thus converted is supplied to a VTR section (6) through a change-over switch (5). One of the digital video signal from the rate conversion circuit (9) and the reproduction digital video signal from the VTR section (6) is selected by a switch (10). The selected digital video signal is supplied to a D/A conversion circuit (11) and fetched a digital output terminal (12). An analog video signal converted bye the D/A conversion circuit (11) is supplied to a display section (13) consisting of a liquid crystal display unit or the like and built in the device and fetched at an analog output terminal (14).

Abstract: An image recording/replaying device, such as a video camera, has various operating switches which have enhanced operability so as to suit a mode of use. The image recording/replaying device includes an image display section (3) that is foldably, unfoldably, and rotatably supported at a body (2) internally incorporating a taking lens (4). The image recording-replaying device also includes a control switch (14) including an operating key (15) and a plurality of contacts disposed at end portions and an intersection of a cross-shaped portion of the operating key in correspondence with end portions and the central portion of the operating key, in which, by pressing any one of the end portions and the central portion of the operating key, the contact disposed in correspondence with the pressed portion is closed. The control switch further includes direction selection switches which are such that particular directions within a display screen of the image display section correspond to the directions of the positions of the four end portions of the operating key. The direction selection switches are such that the directions used within the display screen of the image display section and corresponding to the directions of the positions of the four end portions of the operating key are changed in accordance with a change in the orientation of the image display section resulting from rotation of the image display section.
