Question about Olympus Camedia C-3040 Zoom Digital Camera
How exactly does a ISO 100, 200, 400 rating work on digital camera. When it is in auto mode what the camera use to decide what ISO to use?
Posted by Anonymous on
Basicly the charge in each pixel on the CCD chip is sent to another chip that converts it to a number. The charge can be amplified before conversion to get larger numbers. The more the charge is amplified the higher the ISO rating, the problem is that noise is also amplified. Just like if you turn up the volume on a weak AM radio station the static is also louder. I'm not sure how the cameras decide on what ISO to use in auto mode, each one is probably programed a little different.

The iso works on the available light the less light the higher the iso will be

The ISO in the camera on Auto mode is selected based upon light levels and on the focal length of the lens. This is adjusted slightly depending upon wich mode you are in. For instance, if you zoom in close to something and lighting is not too good, it'll bump the iso up to 400 or 800 depending upon the camera. Judging from ISO levels in my camera on auto mode, it appears that olympus has developed an program that sets ISO just high enough to offset camera shake based on focal length.

see many a times the drivers files are corrupted after a particular period of time due to loading of some other softwares or programs getting crosslinked with few necessary files.i would suggest you to uninstall the driver completely first then install it fresh again.its a common problem and will get solved after reloading fresh drivers again.thanks.

Thank you for using FixYa for your problem
Always check the batteries first but if is it still giving the same fault, your camera is faulty. "Zoom error" is repairable
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.
