Afaik:

Think of it like this, supposed the APS-C sized sensor only recorded light in a middle rectangle which has 1/2 the length of the sensor. If it was only taking information from there, the crop factor would be different (think of a 4/3rds sensor or compact sensor, they have higher crop factors so the image recorded will be more 'zoomed in) so you would get a different image.

So the sensor must use ALL the pixels and downsize the image.
