That is a pretty bad image. I wouldn't advise camera's of this quality to be used for any serious application where the image may be relied on. Although in my experience with two different versions of this camera, they well exceeded my expectations and perform very well. I have tested them in a range of lighting situations but have not experienced image quality as poor as what you have shown, even using the default camera parameters. Did you try changing the settings from the default at all to work with the lighting conditions?
