Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope apparatus, and more particularly to an endoscope apparatus that captures a narrow space of a human body or a machine.
The endoscope enables to observe and observe a narrow space inside the human body or inside the machine. In particular, the endoscope used in the medical field can be checked by observing the inside of the human body (stomach, bronchus, esophagus, large intestine, small intestine, etc.) by using a small camera without opening or cutting the body such as surgery or autopsy do.
In general, an endoscope system includes a light source for irradiating a white light for viewing the internal organs of the body or the internal surface of a machine, and an imaging device for receiving an optical signal reflected from the surface of the internal organs of the body and converting the light into an electrical signal And an imaging element assembly including the imaging element assembly.
Such an endoscope apparatus employs a CCD (Charge Coupled Devices) sensor and a CMOS (Complementary Metal Oxide Semiconductor) sensor as image pickup devices, and thus it has been possible to obtain a high-quality image.
However, since the CCD sensor or the CMOS sensor is applied to the image pickup device, the conventional endoscope device is insufficient to transmit a large-capacity high-resolution image due to the limitation of the transmission speed.
BACKGROUND ART [0002] The background art of the present invention is disclosed in 'Electronic Endoscope System' of Korean Patent Laid-Open Publication No. 10-2008-0051154 (Jun. 10, 2008).
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a low-noise and low-power high-resolution image transmitted / received between a tip module and a handle module by using an endoscopic camera image sensor of MIPI (Mobile Industry Processor Interface) And an endoscopic device capable of transmitting an endoscope.
Yet another object of the present invention is to provide an endoscope apparatus in which the size of the tip module is reduced by separating an image signal processor (ISP) included in the image sensor from the image sensor to reduce the size of the image sensor .
An endoscope apparatus according to one aspect of the present invention includes: a tip module that is inserted into a body and captures an image, converts a captured image signal into a Mobile Industry Processor Interface (MIPI) image signal, and transmits the image signal through a cable; A handle module for processing and transmitting the MIPI video signal transmitted through the cable from the tip module; And a video output module for receiving, processing, and outputting image data transmitted from the handle module.
In the present invention, the tip module may include an illumination unit for illuminating the body; lens; And an image sensor which photographs the body through the lens in the illuminated state through the illumination unit, converts the photographed image signal into a MIPI signal, and transmits the MIPI signal to the tip module through the cable.
In the present invention, the handle module may include an image signal processor for performing an image correction process on the MIPI image signal transmitted from the tip module.
In the present invention, the handle module may further include a transmitter for transmitting the signal processed by the video signal processor to the video output module.
In the present invention, the video output module may include: a receiver for receiving image data transmitted from the handle module; A display server for processing and analyzing image data received at the receiver; And a display device for displaying an image transmitted from the display server.
The present invention makes it possible to transmit a high resolution image transmitted between a tip module and a handle module using low noise and low power by using the MIPI scheme.
The present invention reduces the size of the image sensor so that the size of the endoscope tip module can be reduced.
