camera mobile phones


A camera phone is a mobile phone which is able to capture either still photographs or motion video. Today more than half The camera phone, like many complex systems, is the result of converging and enabling technologies.

There are dozens of relevant patents dating back as far as the 1960s. Compared to digital cameras of the 90s, a consumer-viable camera in a mobile phone would require far less power and a higher level of camera electronics integration to permit the miniaturization. The CMOS active pixel image sensor "camera-on-a-chip" developed by Dr. Eric Fossum and his team in the early 1990s achieved the first step of realizing the modern camera phone as described in a March 1995 Business Week article. While the first camera phones, as successfully marketed by J-Phone in Japan, used CCD sensors and not CMOS sensors, more than 90% of camera phones of all mobile phones in use are camera phones.

The BlackBerry is a wireless handheld device introduced in 1999 as a two-way pager. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services. It is an example of a convergent device. Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies. BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect software. The original BlackBerry device had a monochrome display, but all current models have color displays.
While including PDA applications (address book, calendar, to-do lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is primarily known for its ability to send and receive e-mail wherever it can access a wireless network of certain cellular phone carriers. It has a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type. System navigation is primarily accomplished by a scroll ball in the middle of the device (older devices used a track wheel on the side). Some models (currently, those manufactured for use with iDEN networks such as Nextel and Mike) also incorporate a Push-to-Talk (PTT) feature, similar to a two-way radio.
Modern BlackBerry handhelds incorporate an ARM 7 or 9 processor, while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The latest GSM BlackBerry models (8100, 8300 and 8700 series) have an Intel PXA901 312 MHz processor, 64 MB flash memory and 16 MB SDRAM.[2] CDMA BlackBerry smartphones are based on Qualcomm MSM6x00 chipsets which also include the ARM 9-based processor and GSM 900/1800 roaming (as the case with the 8830).[3][4] The devices are very popular with some businesses, where they are primarily used to provide e-mail access to roaming employees. To fully integrate the BlackBerry into a company's systems, the installation of BlackBerry Enterprise Server (BES) is required

Treo 650


The Palm Treo 650 is a combination hybrid PDA/cellphone officially announced on October 24, 2004 as the successor to the company's Treo 600. It began shipping in November 2004, but is not shipped anymore. The CDMA version has been superseded by newer models such as the Treo 700p, Treo 755p, Treo 700w, and the Treo 700wx, while the GSM version has been superseded by the Treo 680 and Treo 750v.

TOUCH SCREEN MOBILES,PDAs






Many original PDAs, such as the Apple Newton and Palm Pilot, featured touch screens for user interaction, having only a few buttons usually reserved for shortcuts to often used programs. Touch screen PDAs, including Windows Pocket PC devices, usually have a detachable stylus that can be used on the touch screen. Interaction is then done by tapping the screen to activate buttons or menu choices, and dragging the stylus to, for example, highlight. Text input is usually done in one of four ways:
Using a virtual keyboard, where a keyboard is shown on the touch screen. Input is done by tapping letters on the screen.
Using external keyboard or corded keyboard connected by USB, IR or Bluetooth.
Using letter or word recognition, where letters or words are written on the touch screen, and then "translated" to letters in the currently activated text field. Despite rigorous research and development projects, end-users experience mixed results with this input method, with some finding it frustrating and inaccurate, while others are satisfied with the quality.[1] Recognition and computation of handwritten horizontal and vertical formulas such as "1 + 2 =" was also under development.
Stroke recognition (termed Graffiti by Palm). In this system a predefined set of strokes represents the various characters needed. The user learns to draw these strokes on the screen or in an input area. The strokes are often simplified character shapes to make them easier to remember.
PDAs for business use, including the BlackBerry and Treo, have full keyboards and scroll wheels or thumb wheels to facilitate data entry and navigation, in addition to supporting touch-screen input. There are also full-size foldable keyboards available that plug directly, or use wireless technology to interface with the PDA and allow for normal typing. BlackBerry has additional functionality, such as push-based email and applications.
Newer PDAs, such as the Apple iPhone and iPod touch include new user interfaces using other means of input. The iPhone and iPod touch uses a technology called Multi-touch.

palmtop computers


FEATURES

a palmtop computer is the same as the PDA.

Currently, a typical PALMTOP COMPUTER has a touch screen for entering data, a memory card slot for data storage and at least one of the following for connectivity: IrDA, Bluetooth and/or WiFi. However, many PALMTOP COMPUTERS(typically those used primarily as telephones) may not have a touch screen, using softkeys, a directional pad and either the numeric keypad or a thumb keyboard for input.
Software typically required to be a PALMTOP COMPUTERS include an appointment calendar, a to-do list, an address book for contacts and some sort of note program. Connected PALMTOP COMPUTERS also typically include E-mail and Web support.

personal digital assisstant(PDA)


A personal digital assistant (PDA) is a handheld computer also known as palmtop computers. Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones, (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.
The first PDA is considered to be the CASIO PF-3000 released in May 1983. GO Corp. was also pioneering in the field. The term was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. In 1996 Nokia introduced the first mobile phone with full PDA functionality, the 9000 Communicator, which has since grown to become the world's best-selling PDA and which spawned a category of phones called the smartphone. Today the vast majority of all PDAs are smartphones, selling over 150 million units while non-phone ("stand-alone") PDAs sell only about 3 million units per year. The RIM Blackberry, the Apple iPhone and the Nokia N-Series are typical smartphones.
