[dchvs99]

Using a number of exposures equal to 4 results invalid on the TIOVX side. According to the plugin this value is supported:

  num-exposures       : Number of exposures for the incoming raw image.
                        flags: readable, writable, controllable, changeable only in NULL or READY state
                        Integer. Range: 1 - 4 Default: 1
