Logic on an already existing ASIC is going to be cheaper than a capacitor.

This is counter-intuitive enough to warrant further explanation.

If you are designing an ASIC for the camera, you can include all the required logic gates to control the LED for a cost that is close to zero. It wouldn't impact the production cost of the ASIC, whereas a capacitor is an additional item in the BOM (and to be charged it requires current, more than the LED, so the driver in the IC must be bigger).
