Abstract

An apparatus for recording/reproducing an image, includes a unit for switching between an image signal read from an image sensor in units of pixels and a reproduction signal from a recording medium, an A/D converter for converting the image signal from the switching unit into a digital signal, a one-frame solid-state memory for storing the digital image signal, and a processing unit for processing the digital image signal. The processing unit is switched in photographic and reproduction modes to process the image signal stored in the solid-state memory in different operation modes, thereby performing excellent signal processing even if the image signals stored in the solid-state memory have different formats in the photographic and reproduction modes.

Claims

1. An apparatus for recording/reproducing an image, comprising:

a) a color image sensor for converting radiation from an object into a color image signal;

b) means for reproducing a color signal recorded in a medium from the medium to which a signal corresponding to the color image is to be recorded;

c) an A/D converter;

d) means for selectively supplying an output from said image sensor or an output from said reproducing means to said A/D converter;

e) means for inputting a normalized image signal from an external device; and

f) means for converting the normalized image signal into a signal having the same format as that of the signal reproduced from the medium.

2. An apparatus according to claim 1, wherein said medium comprises a disk-like medium.

3. An apparatus according to claim 1, wherein the normalized image signal is an image signal complying with NTSC standards.
