This is definitely true. The resolution you need is a function of range, target geometry, angle of incidence, camera field of view, the frequency and type of non-target objects that pass the threshold, and required precision. 640x480 has been overkill for all vision challenges to date.
640x480x30 fps is a convenient benchmark, though, as it is achievable with largely unoptimized code by many forms of coprocessors.
