Abstract

A video camera with a monitor, which is provided integrally on both surfaces or the same one surface of a semiconductor substrate or a substrate having a semiconductor film thereon; an image pickup plate and a display unit in one functioning as the image pickup plate for converting an optical image into an electrical signal and the display unit for converting the electrical signal into a visual image; the camera is provided with an optical system for imaging the optical image on the pickup plate.

Claims

1. A video camera with a monitor, comprising:

an optical system for imaging an optical image;

an image pickup-and-display unit which comprises an image pickup portion formed on one surface of a semiconductor substrate for converting said optical image to an electrical signal, and an active matrix type image display portion formed on another opposite surface of said semiconductor substrate for converting said electrical signal to a visual image, said semiconductor substrate being common to both said image pickup portion and said image display portion;

an image pickup portion control circuit for controlling said image pickup portion.

2. A video camera with a monitor according to claim 1, wherein said semiconductor substrate is formed of crystalline silicon.

3. A video camera with a monitor according to claim 1, wherein said semiconductor substrate comprises an insulating substrate provided on both surfaces thereof with one of either a monocrystalline, polycrystalline, or amorphous semiconductor film.

4. A video camera with a monitor according to claim 1, wherein said image display portion comprises one of either a liquid crystal display system, an electrophoretic display system, an electrochromic layer, an electroluminescence layer, or a fluorescent layer for a slow electron cathode luminescence.

5. A video camera with a monitor, comprising:

an optical system for imaging an optical image;

an image pickup-and-display unit which comprises an image pickup portion formed on one surface of a semiconductor substrate for converting said optical image to an electrical signal, and an active matrix type image display portion formed on said one surface of said semiconductor substrate for converting said electrical signal to a visual image, said semiconductor substrate being common to both said image pickup portion and said image display portion;

an image pickup portion control circuit for controlling said image pickup portion; and

an image amplifier coupled to said image display portion for amplifying the electrical signal from said image pickup portion.

6. A video camera with a monitor according to claim 5, wherein said semiconductor substrate is formed of crystalline silicon.

7. A video camera with a monitor according to claim 5, wherein said semiconductor substrate comprises an insulating substrate provided on one surface thereof with one of either a monocrystalline, polycrystalline, or amorphous semiconductor film.

8. A video camera with a monitor according to claim 7, wherein said insulating substrate is formed of sapphire and said semiconductor film is formed of crystalline silicon.

9. A video camera with a monitor according to claim 5, wherein said image display portion comprises one of either a liquid crystal display system, an electrophoretic display system, an electrochromic layer, an electroluminescence layer, or a fluorescent layer for a slow electron cathode luminescence.
