The sensor size doesn't change anything. A camera with a larger sensor would have the same image projected on the sensor but it would also capture more around it - basically, you could get the same image by cropping that part out of the larger image. However, a larger sensor probably would have larger pixels, which would help with lighting and noise reduction.
