I have directly interfaced the BBB with low cost camera modules using a PRU on the TI AM335x. I have only tried using the parallel digital video port (DVP) type of image sensor interface. I used PRU1 since it has a maximum of 15 input pins available [PRU0 has a maximum of 11 input pins available] and I wanted to support 10-bit DVP which requires a total of 13 input pins (10 data out, a pixel clock, a horizontal reference, and a vertical sync).
My design includes provision for a crystal oscillator to clock the image sensor, but a timer (timer4, timer5, timer6, or timer7) on the AM335x can be used to supply a clock. So it is possible to interface directly (without any glue logic).
