Help for find Camera Datasheet or interface to st32f103
I'm not saying that you will NOT find this data sheet.  Do keep trying.  But in general, data sheets for SOC's, cameras etc. that are used in the handset market are generally only released on NDA and are not generally available.

You can see this on sites like Spark fun that sell the modules but can't supply the data sheets.

However, there are a couple things you can do.  These devices typically are on MIPI interfaces and also conform to standard I2C or I2S interface's with semi-similar register mappings.  the electrical interfaces will be standardized, it's the register mappings and uses that might be hard to determine.  However, a lot of these cameras are supported under Android which is open source, there will be generic camera register mappings in that source code.  Some of the cameras driver modules are proprietary, but people have published them anyways.

Look around for these forums for guidance.
