## Abstract

The present invention relates to a portable CCD camera imaging device for the human body, comprising: a handle-shaped main body (10); a tube body (20) projecting from the leading end of the main body (10) at an angle to the main body (10) and having a diameter that enables the insertion thereof into a hole in a human body; a CCD camera (30) inserted into the inner diameter of the tube body (20); LEDs (40) installed around the perimeter of the CCD camera (30); and a transmitting ring (50) transmitting light from the LEDs (40) at a uniform brightness, and having a convex portion (52) for diffusing the transmitted light.

## Claims

### Claim 1

A portable skin imaging system for the human body, comprising:
a main body (10) shaped to be easily gripped by the hand;
a pipe-like body (20), formed on the top of the main body (10), for putting in the cavity of the human body, the lengthwise axis being inclined against that of the main body (10), and the tip being protruded in the lengthwise direction from the main body (10);
a charge coupled device (CCD) camera module (30) installed inside the pipe-line body (20);
LEDs (40) installed sparsely around the CCD camera module (30); and
a light transmission material ring (50) with a convex portion (52) for uniformly diffusing the light from the LEDs (40).

### Claim 2 (depends on 1)

The portable skin imaging system according to claim 1, wherein the light transmission material ring (50) is fixed to the front top of the pipe-line body (20) so that it can be located at the front end of the lens module of the CCD camera module (30).

### Claim 3 (depends on 1)

The portable skin imaging system according to claim 1, wherein:
the light transmission material ring (50) forms, in the inside, a pattern layer (53) for limiting the light transmission of light emitted from the LEDS (40); and
the pattern layer (53) increases larger patterns (51) in parts where the LEDs (40) exist and gradually decreases the patterns in parts where the LEDs 40 do not exist.

### Claim 4 (depends on 1)

The portable skin imaging system according to claim 1, wherein the CCD camera module (30) comprises:
a lens module (32) shaped a pipe, for adjusting the focus; and
a CCD chip (34) installed inside the lens module (32), for reading video data, and
wherein:
the lens module (32) forms a guide groove (33) on the outer surface in the lengthwise direction, the guide groove (33) guiding the movement of a guide (24) protrudently formed on the inner wall (22) and forms, on the outer surface, a spur rack gear (26) for transferring movement power; and
the spur rack gear (26) is engaged with spur gears (28) one of which is partially exposed from the pipe-line body (20) or the main body (10) and rotated by the user's finger.

### Claim 5 (depends on 2)

The portable skin imaging system according to claim 2, wherein:
the light transmission material ring (50) forms, in the inside, a pattern layer (53) for limiting the light transmission of light emitted from the LEDS (40); and
the pattern layer (53) increases larger patterns (51) in parts where the LEDs (40) exist and gradually decreases the patterns in parts where the LEDs 40 do not exist.

### Claim 6 (depends on 2)

The portable skin imaging system according to claim 2, wherein the CCD camera module (30) comprises:
a lens module (32) shaped a pipe, for adjusting the focus; and
a CCD chip (34) installed inside the lens module (32), for reading video data, and
wherein:
the lens module (32) forms a guide groove (33) on the outer surface in the lengthwise direction, the guide groove (33) guiding the movement of a guide (24) protrudently formed on the inner wall (22) and forms, on the outer surface, a spur rack gear (26) for transferring movement power; and
the spur rack gear (26) is engaged with spur gears (28) one of which is partially exposed from the pipe-line body (20) or the main body (10) and rotated by the user's finger.
