Abstract

PURPOSE: A PDA(Personal Digital Assistant) with camera functions is provided to enable a user to capture desired images by supplementing PDA with camera functions and to identify the user's identity through iris identification or fingerprint identification by using image sensors. CONSTITUTION: A PDA(Personal Digital Assistant) with camera functions is composed of filming, input, storage, and identification. A user films a desired image through an image sensor(20) and a key input department(10). The filmed image is inputted to a camera controller(20) and processed by it. A CPU(40) controls input and procession operations of the key input department and the camera controller and the inputted and processed visual image is stored in a data storage(60). The CPU can also store the visual data in a detachable memory stick(70) that possesses four or eight M bytes of memory space. An image sensor(30) also executes user identification function through iris identification and fingerprint identification of a close-up filming. A display(50) displays operation status and result in accordance to the CPU's control. The charged battery provides power for an operation(80) and it connects to an external recharger and replenishes electricity through a lower charge terminal(81).

Description

PD having a camera {PDA having a camera}

The present invention relates to PDA (Personal Digital Assistants), and more particularly to a PDA having a camera function for image recognition.

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 a camera function to a conventional PDA so that the user can take a desired image, and also has a camera function to confirm the identity of the user through iris recognition or fingerprint recognition using the imaging device. In providing a PDA.
