Description

[DESCRIPTION]
[invention Title]
HIGH-MAGNIFICATION IMAGING DEVICE FOR MOBILE PHONE
[Technical Field] The present invention relates to a high-magnification imaging device for a mobile phone, which is configured such that a lens unit, having a high-magnification function, is detachably attached to the mobile phone and, more particularly, to a high-magnification imaging device for a mobile phone, which is configured such that a lens unit, which is located in front of and in line with the camera (Charge Coupled Device type or Complementary-Metal Oxide Silicon type) of the mobile phone and implements a high- magnification microscope function is detachably attached, and can be used for medical treatment, education and study, agriculture, industry, etc.
That is, the present invention relates to a high- magnification imaging device for a mobile phone, which provides a microscope function to the mobile phone, so that it can be used as a medical treatment device capable of providing scientific and reasonable medical functions by capturing an overall magnified image of a diseased part of a patient (of, for example, dentistry, otorhinolaryngology, enterology and proctology, or dermatology) and performing precise diagnosis and prescription, as an education or study device capable of being used for education or study by capturing and magnifying images of plants, insects or the like, as an agricultural device capable of examining and preventing damage from disease and harmful insects by capturing and magnifying images of crops, and as an industrial device for analyzing the print quality of the halftone dots of printed material, the adhesive states of the adhesive portions of the printed material, the state of foam of rubber products, such as natural or synthetic rubber, for capturing and examining images of home ticks, and for examining the surfaces of products . Furthermore, the present invention relates to a high-magnification imaging device for a mobile phone, which can transmit and use captured and magnified images of subjects using a remote system based on mobile communication technology, which enables measurement, diagnosis and examination by capturing and magnifying images for the above-described uses regardless of time and place, and which is convenient to carry.
[Background Art] Recently, with the development of electronic and communication technology, portable telephones or cellular telephones (hereinafter referred to as "mobile phones") are gradually becoming compact and having diverse functions .
Currently, as mobile phones develop into modern conveniences, most people use them as mobile communication devices, and the number of users thereof is rapidly increasing. Generally, mobile phones are classified into a bar type, a flip type, and a folder type, and each mobile phone is provided with an earphone, a microphone, a Liquid Crystal Display (LCD) panel, a keypad, and a battery in the main body thereof. Generally, a connecting slot for receiving a plug-in connector to electrically connect to the outside is provided in the center portion of the lower end of the mobile phone in the length direction thereof.
The connecting slot is connected with a hands-free device, a charger, or a computer, or is used to connect one of several types of terminals, that is, a communication terminal, a power terminal, and other special function terminals, for example, to charge the battery.
Representative additional functions of the mobile phone include various functions such as an alarm function, a speech recognition function, a quick dial function, a text message transmission and reception function, a bell sound change function and a gaming function. Recently, products having an advanced communication function capable of immediately transmitting and receiving captured still images and moving images using a mobile phone with which a small-sized camera is equipped, as well as an Internet connection function, such as text message transmission and electronic (e) -mail transmission, have also been commercialized.
Meanwhile, although small-sized cameras mounted in existing mobile phones and configured in the form of cameras having lenses having a zoom function have been commercialized, the existing cameras cannot capture images at high magnification because the magnification of the lenses thereof is low.
That is, existing cameras have limited ability to capture images at high magnification and to detect the state of the skin of the human body, such as pores, pigment deposition, keratin, and atopy, the state of the hair, or information about patients' diseased body parts in the fields of dentistry, otorhinolaryngology, enterology and proctology, or dermatology. Furthermore, the existing cameras are limitedly able to detect plants or insects, damage to crops due to disease and harmful insects, the printed states of the halftone dots of printed material, the adhesive states of the adhesive portions of printed material, the state of foam of rubber products, such as natural or synthetic rubber, home ticks, and whether faults exist on the surface of processed metal or the surfaces of products .
In consideration of the problems, there have been attempts to combine a close-up lens (a lens for increasing the function of a lens to high-magnification) with a lens having a magnifying power of 1 (hereinafter referred to as an "object lens") and increase the magnification of the lens to high magnification, but problems occurs in that the specifications of the lenses of mobile phones are different for each manufacturing company and are different for each model of mobile phone even within the same manufacturing company, and the casing structures of the mobile phones and the installation locations and structures of cameras are also different, so that a different close-up lens unit to be combined with the object lens of the mobile phone must be constructed for each mobile phone manufacturing company or for each model . Furthermore, when production of the mobile phone is discontinued, a problem occurs in that the production of the close-up lens must be discontinued.
For the above-described example, a technology in which a unit detachably couples a close-up lens in front of the camera of a mobile phone was proposed in Japanese Unexamined Pat . No . 2003-315905 (hereinafter referred to as a "cited reference") .
That is, the cited reference proposed a construction in which the unit is detachably coupled by first and second members 2 in front of the camera of the mobile phone, and the unit is provided with a magnifying lens, a light source and a battery therein.
However, the cited reference is configured such that power for the light source is supplied by a battery within the unit, so that a large amount of light cannot be emitted using only the power of the battery and the light is not very bright, therefore, high-magnification image capture is impossible. Furthermore, the life span of the battery is short, so the battery must be frequently changed, therefore inconvenience results and a high cost is incurred.
Furthermore, in order to acquire a high- magnification image, the lamp, the lens, and the camera must be stably formed in a line . However, the cited reference is configured such that the light source is formed on the outer circumference of the magnifying lens, and the unit is detachably attached to the mobile phone by the first and second members formed in an irregularly (tH]β) structured unit, so that the irregular (IHlfi) structure becomes loose when the unit is detached or attached several times, therefore, the structure of the optical system, which must be accurate, is unstable.
In this case, the accuracy of the optical system structure is unstable, so that high-magnification images cannot be acquired.
Furthermore, in the case where the unit is detached from or attached to the mobile phone using the irregular (HU) structure of the first and second members, the irregularities must exactly fit, so that it is inconvenient to couple the unit, and a long time is required to couple the unit, therefore the structure of the optical system cannot be easily and rapidly assembled.
Furthermore, in order to detach or attach the unit to/from the mobile phone, a first member must be separately and fixedly installed in front of the camera of the mobile phone and a second member must be fixedly installed in the unit . This is also inconvenient, and the cameras of mobile phones that have already been commercialized differ with respect to location, structure, and/or size, so that there are limitations in applying the unit to general mobile phones and detachably attaching it to general mobile phones using only the first and second members . Furthermore, the close-up lens is attached to the front of the object lens (lens having a magnifying power of
1) , which is formed in the mobile phone, to change the lens function to one of high magnification. In such a technology, a compatibility problem occurs in that the specifications and details of objective lenses formed in the mobile phones are different among respective companies manufacturing the mobile phones or among models, so that close-up lenses and units that are suitable for respective models must be manufactured.
That is, the cameras in existing commercialized mobile phone are of a Video Graphic Array (hereinafter referred to as "VGA") class of camera cells or a MEGA class of camera cells, depending on the number of pixels . Accordingly, the lens (object lens) that is installed in a VGA class or MEGA class camera phone is respectively suitable for the VGA class or the MEGA class .
In the case where a close-up lens is attached to the front of the lens (object lens) of the camera phone lens as in the cited reference, the close-up lens also must be close-up lens suitable for the VGA class or the MEGA class according to a lens camera cell .
Assuming that a camera cell in the cited reference belongs to the VGA class, a close-up lens suitable for the VGA class must be manufactured, and then attached using a unit in order to be used.
However, it is impossible to detach a unit in which a VGA class close-up lens is formed, attach it to a MEGA class commercialized camera phone, and use the camera.
The reason is because the ray resolution differs between a close-up lens suitable for the VGA class and the object lens of the MEGA class camera cell . Furthermore, in the case where the close-up lens is manufactured to be suitable for the MEGA class and is attached to a VGA class camera phone, it is impossible to use the camera phone for the same reason described above.
Accordingly, the technology of attaching a separate close-up lens as in the cited reference requires that a lens suitable for each model of camera phone be manufactured. In this case, the close-up lens must be manufactured in consideration of the material for the close-up lens, the process method thereof, the design data, the number of lenses, and the like, so that the manufacture thereof is very difficult and a high manufacturing cost is incurred, therefore competitiveness is lowered. In particularly, it is known that a close-up lens suitable for the MEGA class has not been manufactured to date, and it has not been possible to realize it in industry.
