NewSoftSerial library is not recognized by arduino

Hello!!
I am trying to connect arduino to a camera, purchased from-

and also downloaded the sample code provided on same page. While compiling i got an error

In file included from LinkSprite_cam_IR.ino:3:
C:\Users\trutech\Documents\Arduino\libraries\NewSoftSerial/NewSoftSerial.h:33:2: error: #error NewSoftSerial has been moved into the Arduino core as of version 1.0. Use SoftwareSerial instead.

this is code snippet as a reference

#include <NewSoftSerial.h>
byte incomingbyte;
NewSoftSerial mySerial(4,5);                     //Configure pin 4 and 5 as soft serial port
int a=0x0000,j=0,k=0,count=0;                    //Read Starting address       
uint8_t MH,ML;
boolean EndFlag=0;

please suggest,how do i resolve this error.

NewSoftSerial is called SoftwareSerial in IDE versions 1.0 and above. So the include looks like this:

#include <SoftwareSerial.h>
SoftwareSerial mySerial(4,5);

Hello!!
I am stuck in a new problem, after running the code i got a stream of Hex value at Serial monitor(may be image raw data). Can any body suggest how do i get a proper image.
i m using this camera on arduino uno.
complete code is available at sparkfun's link LinkSprite JPEG Color Camera TTL Interface - Infrared - SEN-11610 - SparkFun Electronics

That code is sending the received image as ASCII in hexadecimal notation to the connected PC. You do get a proper image you just have to decode the hexadecimal data back into binary on the PC and save it. Another possibility is to send the binary data directly but then you might have the problem to detect the end of the transfer.

What do you want to achieve? What should the Arduino do for you?

I am trying to implement gesture using arduino and camera. I read some previous queries(questions) related to camera and found that arduino is not capable to process captured image.
Is there any way using which I can implement gesture.??

Using what? Just an Arduino and a camera? Perhaps you missed something here:

I read some previous queries(questions) related to camera and found that arduino is not capable to process captured image.

So, let me paraphrase that for you. No.

i found some solution like , ultrasonic range finder sensor + arduino or using accelerometer and arduino.
which one is better to go with?

What kind of gestures do you want to recognize?

Why did you choose an Arduino and not a more powerful platform (like a standard PC or one of the ARMs available in a variety of form factors)?

With an ultrasonic range finder you won't be able to do anything which is worth getting the name gesture recognition. So if your choices are limited to these two, choose the later one but only if that limitation is given and you have no other option.
