I'm sorry for my English, I'm from Russia. I need yours help. Please tell me, it is possible and if yes, please explain how. I need next features for my Power Shot A480:

2. When camera in photo mode, I need for picture that on LCD display translated on Video output (AV connector)
3. To disconnect the function of auto power off function in photo mode.

A480 has no iris. It has an ND filter.
For operating without lens, maybe http://chdk.setepontos.com/index.php?topic=3409.0 will help you

CHDK should allow this, "disable LCD off" -  "Always"
Don't forget what the H stands for.

If you remove the lens, you still need a tiny mechanical shutter to block the light while the sensor is being read.

If you do not have a shutter, the image will consist of bright and dark lines.
