Is it possible to take a picture from a paper with infrared image sensor without lighting?
CCD sensors are inherently more sensitive to IR than CMOS...part of the advantage of CMOS sensors for "normal" cameras is that they don't have as much inherent "IR preference," so less IR filtering is required to take "visible spectrum" photographs.
Usually, any image sensor that comes with its own IR LEDs will be producing FAR MORE IR illumination than you need for reading a sheet of paper right in front of the imager...you'll probably have to add series resistors to the LEDs to reduce their output and keep them from "washing out" your images.
IMHO, you should **not* use a "camera" to scan something on a flat surface; a line scan sensor/linear CCD is the more appropriate tool for the job (similar to a camera, but only 1 row of pixels on the sensor, and easier to focus on a closer "target"). Here's One for an example of a device that should work better.
If you use a CMOS image (rather than linear) chip, then you'll need to look at finding a "wide-angle macro" type lens to enable the imager to "see" the whole sheet of paper, and also focus, at any reasonably close range.
