Description

PD having a camera {PDA having a camera}

The present invention relates to a personal digital assistant (PDA), and more particularly, to an iris / fingerprint recognition function for recognizing a user's iris or fingerprint to a PDA capable of capturing an image through a photographing device, thereby preventing leakage of user information. In addition, the present invention relates to a PDA having a camera function that stores a captured image on a separate memory stick and easily connects to a peripheral device.

In general, PDAs are personal handheld devices that combine information collection, storage, creation, retrieval, and communication functions, and their use is increasing. Looking more closely at such PDAs, PDAs can be called personal digital assistants (PDAs), which are much smaller than laptops, but with more power than electronic notebooks. Personal information management programs such as schedule management, address book, and notepad are basically provided, and data can be exchanged freely through PC connection, and new programs can be installed and used in addition to the built-in programs.

Meanwhile, PDAs have recently been pioneering new wireless Internet fields. For example, by default, PDAs improve the inefficient method of personal management through the built-in programs and additional applications, and also provide personal information management programs for PCs that correspond to personal information management programs of PDAs. By connecting PDA and PC, it supports modification, addition, and backup of inputted information, showing new personal information management plan. In addition, the wireless Internet is connected to a mobile phone, web page search, e-mail transmission, PC communication, stock trading, etc., the main functions of the Internet that can be performed on a PC is also possible in the PDA. Applications include management automation (data collection, data exchange, activity monitoring, work assignments, order entry, billing and customer database access), transportation and inventory management (product inventory, work placement, process placement, etc.), convenience It is applied to various fields of facilities and public safety (accident reporting, parking control, emergency services and repairs, meter reading, maintenance and auditing functions, etc.), and the financial industry (sales agents of insurance and mutual fund companies, collection of customer-related information, etc.). .

Recently, products having added various functions to such a conventional PDA have been developed, and thus the present applicant has come to develop a more convenient product by adding a new function to the conventional PDA.

Accordingly, an object of the present invention is to add an iris / fingerprint recognition function for recognizing the iris or fingerprint through the image pickup device to prevent leakage of user information to the PDA that can take an image through the image pickup device, the image taken It is to provide a PDA having a camera function further equipped with a separate memory stick so that it can be connected to the storage and peripheral devices.

According to an aspect of the present invention, a data storage unit, a central processing unit, a key input unit, a display unit, and an image pickup device for inputting an image and a camera control unit for processing the same are provided. A user's iris / fingerprint recognition unit for controlling the operation of the central processing unit through a user identification function for recognizing the iris or a fingerprint by contrasting the recognized iris or fingerprint with a user's iris or fingerprint previously input to the data storage unit; A memory stick for storing the image data input through the image pickup device, which can be easily detached and used on the main body of the PDA, is further provided.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a control block diagram of a PDA having a camera function according to the present invention, Figure 2 is an external perspective view of a PDA having a camera function according to the present invention.

As shown, the present invention includes a key input unit 10 for inputting a user's command through a key; An imaging device 30 for inputting an image; A camera controller 20 for processing an image input to the imaging device 30; A central processing unit (40) for controlling the input and processing operations of the key input unit (10) and the camera control unit (20), and storing the input and processed image data in the data storage unit (60); A removable memory stick (70) for storing the image data by the central processing unit (40); A display unit 50 for displaying an operation state and a result according to the control of the central processing unit 40; A charging battery 80 for supplying power to the respective parts; A charging terminal 81 connecting the charging battery 80 to an external charger; Recognizes the iris or fingerprint by close-up photography of the imaging device, recognizes the iris or fingerprint by close-up photography of the imaging device, contrasts the recognized iris or fingerprint with the user's iris or fingerprint previously input to the data storage unit It consists of a user iris / fingerprint recognition unit that controls the operation of the central processing unit through the user identification function.

Referring to the operation of the present invention configured as described above, the user first captures a desired image through the image pickup device 30 and the key input unit 10, the image is input to the camera controller 20 is processed.

Thereafter, the central processing unit 40 controls the input and processing operations of the key input unit 10 and the camera control unit 20, and stores the input and processed image data in the data storage unit 60 or is provided separately. If the user needs to be selectively stored in the stick 70, the memory stick 70 can be detached and connected to a peripheral device, thereby making it very convenient to use the editing or output.

In addition, the central processing unit 40 may store the image data in the removable memory stick 70, which typically has a storage capacity of 4 to 8 Mbytes.

In this case, the iris / fingerprint recognition unit recognizes the iris or fingerprint of the user photographed in close proximity through the image pickup device 30, and compares the iris or fingerprint of the user photographed in close proximity to the iris or fingerprint of the user inputted previously. Alternatively, if the fingerprint is the same, the use of the PDA is allowed, and if the iris or the fingerprint is different, the operation of the PDA is blocked. That is, the imaging device 30 has the iris or fingerprint recognition function 30. It is possible to recognize the iris or fingerprint by selecting and attaching to the PDA, the iris / fingerprint recognition unit recognized iris or fingerprint compared to the user's iris or fingerprint input to the data storage unit 60 to determine the operation of the central processing unit To control.

On the other hand, the display unit 50 displays the operation state and results under the control of the central processing unit 40, the operating power of each unit is supplied by the rechargeable battery 80.

The rechargeable battery 80 is connected and charged to an external charger by the charging terminal 81 at the bottom thereof.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

As described above, according to the present invention, the iris or fingerprint of the user photographed in close proximity to the photographing device is recognized, and the contrast with the previously inputted iris or fingerprint of the user permits the use of the PDA in the same case and the PDA of the PDA in different cases. An iris / fingerprint recognition unit is further provided to block the use of the iris, and further includes a separate memoristic to store the image input through the photographing device, thereby preventing the leakage of user's personal information stored in the PDA. In addition, by storing the captured image in a separate memory stick, it is possible to expand the data storage unit for storing the image and to easily connect the peripheral device.
