Embedded Image Processing System that sends photos to Smartphone via Bluetooth
This question is more of a hardware setup. Books like Gonzalez will be more relevant when you have images as pixels and process them to transform to more desirable images. 

Here are the few tips: 


Setup a hardware like Raspberry PI - a small general purpose computer
Add hardware I/O interface like Camera Module 
You can use standard USB Dongles and make it work on your pi. 
Write your application which will now collect pics and send across to the app on your smart phone! 


Thats' it, really!
