Hello,
I'm very interested in building a device with an image sensor that is able to do OCR (Optical Character Recognition). What image sensors do you recommend me for this task. I'm hoping to spend no more than 30-40 dollars on the image sensor.
I want to interface the image sensor to a microcontroller and do one of the following:
- process stream of images directly
- send stream of images to PC/smartphone for processing
Basically, I want to point the image sensor at a book for example and recognize the characters. Also, it needs to be small.
I'm from Europe and I'm having a hard time trying to locate good online shops that have these kind of parts.
Any suggestions, help on the image sensor and lens required would be appreciated.

ThanksI'm trying to build a device for blind people. The mini-camera will be mounted on some glasses. Earplugs are attached to the glasses so that the person may hear what the device "sees" using OCR. After that, text to speech must take care of the audio part.
This is the reason I'm trying to build my own camera module, so it has to be small, because I want to integrate it somehow into glasses, maybe behind one of the lenses, or right between the lenses, so that I can integrate other circuits behind the lenses.
