Abstract

Image recording/reproducing apparatus includes a converter for converting radiation from an object into a color image signal. A digital color processor is provided for changing the color image signal converted by the converter to a digital color image. The digital color processor includes a digital signal processor and a ROM for storing program software for the digital signal processor. Preferably, switching structure is provided for switching different types of signals to common A/D converter structure.

Claims

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

a converting means for converting radiation from an object into a color image signal; and

a digital color processing means for changing the color image signal converted by said converting means to a digital color image, said color processing means including a digital signal processor and a ROM for storing program software for said digital signal processor.

2. An apparatus according to claim 1, further comprising a reproducing means for reproducing the image signal from the medium.

3. An apparatus according to claim 1, wherein said digital signal processor performs a processing for converting a format of the color image signal.

4. An apparatus according to claim 1, wherein said converting means comprises a CCD.

5. An apparatus according to claim 1, wherein said converting means includes a CCD and an optical system for irradiating said CCD with light flux.

6. An apparatus according to claim 1, further comprising recording means for recording on a medium the image signal processed by said digital color processing means.

7. An apparatus according to claim 6, wherein said medium comprises a disc.

8. An image processing apparatus comprising:

a) image pickup means for outputting a first signal of a first form;

b) reproducing means for outputting a second signal of a second form different from said first form;

c) an A/D converter; and

d) supplying means for selectively supplying said first signal and said second signal to said A/D converter.

9. An apparatus according to claim 8, wherein said first signal of a first form includes a luminance signal and a color signal.

10. An apparatus according to claim 8, wherein said first signal of a first form includes a luminance signal and a color signal which are time-divisionally transmitted.

11. An apparatus according to claim 8, wherein in said first form and said second form, image information of one picture is transmitted in the same period.

12. An apparatus according to claim 8, wherein said second signal of the second form includes a synchronization signal.

13. An apparatus according to claim 12, wherein when said second signal of the second form, including said synchronization signal, is A/D converted, said A/D converter converts with a sampling rate corresponding to said synchronization signal.

14. An image processing apparatus comprising:

a) image pickup means for outputting a first signal of a first form;

b) reproducing means for outputting a second signal of a second form different from said first form;

c) plural A/D converters;

d) selective supplying means for selectively supplying said first signal and said second signal to said plural A/D converters.

15. An apparatus according to claim 14, wherein said first form is a form in which the luminance signal and the color signal are output through a common line.

16. An apparatus according to claim 14, wherein said second form is a form in which the luminance signal and the color signal are output through different lines, respectively.

17. An apparatus according to claim 14, wherein in said first form and said second form, image information of one picture is transmitted in the same period.

18. An apparatus according to claim 14, wherein said second signal of the second form includes a synchronization signal.

19. An apparatus according to claim 18, wherein when said second signal of the second form, including said synchronization signal, is A/D converted, said A/D converter converts with a sampling rate corresponding to said synchronization signal.
