STM32F4 with DCMI

Hello, we have device with very old TFT display which is dying. New one is unable to obtain. It has similar interface as DCMI: vsync, hsync, pixclk, D0-D8.

I have connected these clock/data lines to DCMI port, but interrupts was not triggered.

Here are my clock lines (from top: vsync, hsync, pix):

I suspect that timing of clock signals is not correct - compared with image I have found:

clock signal is continuous, hsync/vsync falling at the same time... Can somebody confirm this, or can somebody point me to document with detailed dcmi clock format/timing?

Thank you.
mm
