Is there any way to connect my old phone camera with an arduino? I have an esp8266 wifi module, arduino uno and an old mobile. I was wondering if there is any way by which i could remove the camera from the mobile and connect it with my arduino in order to view video captured by the camera. 
Is this possible by the hardware which i currently have? Or i will have to buy more hardware?
Please let me know if more information is required also give the link of helpful articles.

Yes, but it may be a huge amount of work requiring expensive equipment and skills that take decades to acquire.

See Mike's Electric - Interfacing a cheap phone camera module to a PIC32 microcontroller. which is a great video and will give you an idea of what is involved. Note that he's using a 32-bit microcontroller with relatively large RAM on the chip. You might need to use a 32-bit Arduino (Due etc) not one of the 8-bit Arduinos (Uno etc).

Mike is the kind of person who could reverse-engineer a random camera module from an old phone but this isn't a project for a typical Arduino user like you or I.

Since these camera modules cost about $1, it is probably best to look for a camera breakout for Arduino that comes with documentation and software libraries.
