		<summary type="html">&lt;p&gt;DavidCary: another use case for camera as motor/servo controller&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;Interesting suggestions Kimstick! Could you please give us more details what you mean with : &lt;br /&gt;
*Flash mode for rolling shutter&lt;br /&gt;
*Lens distortion hardware correction&lt;br /&gt;
&lt;br /&gt;
-&lt;br /&gt;
*Flash mode for rolling shutter&lt;br /&gt;
The flash should be synchronized with the image sensor.&lt;br /&gt;
Or should an flash occur immediately after the reset of sensor or, if an flash occurred in a random point in time, the sensor has to deliver 2 consecutive frames. &lt;br /&gt;
And knowing the time when an flash of joining them.&lt;br /&gt;
&lt;br /&gt;
''It is possible right now with [[10369]] using [[10369#J15_-_SYNC_.28external.29 | external optoisolated I/O]]. It can produce a pulse to trigger a flash or accept external trigger (in that case there should be sufficient delay between the pulse and a flash - at least equal to a full frame readout/erase time - 1/15sec for the full frame''--[[User:Andrey.filippov|Andrey.filippov]] 09:13, 28 October 2008 (CDT)&lt;br /&gt;

== camera as motor controller ==&lt;br /&gt;
&lt;br /&gt;
Why would you want the camera to be a motor/servo controller?&lt;br /&gt;
Why would you want the camera to be a motor/servo controller?&lt;br /&gt;
&lt;br /&gt;
Why not? is easy. And cam can be funny base for robot.&lt;br /&gt;
&lt;br /&gt;
Because it seems the least silly of these 3 options:&lt;br /&gt;
* Run 2 Ethernet cables up a long pole, one connected to the camera, one connected to a pan-tilt-zoom motor/servo controller&lt;br /&gt;
* Run 1 Ethernet cable up a long pole, connected to a Ethernet hub, with 2 very short Ethernet cables connecting the hub to the camera and the PZT motor/servo controller.&lt;br /&gt;
* Run 1 Ethernet cable up a long pole, connected to the camera, and a short cable for the camera to drive the PZT motors.&lt;/div&gt;</summary>

&lt;div&gt;As user I noticed some things I wanted to have on my camera, I hope anyone that has ideas can add them here. &lt;br /&gt;
What features are you waiting for?&lt;br /&gt;
What software components are still missing that you cannot live without?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

Maybe we should start thinking now about a replacement CPU? Or perhaps, rather than design a new motherboard with a new CPU from scratch, maybe we could consider adapting some other [http://opencircuits.com/Projects#Motherboards_that_Run_Linux open-hardware motherboard that runs Linux]?&lt;br /&gt;
