ABSTRACT:
In a digital camera that captures object light through a CCD and creates an image signal, a CPU and a bias controller set an overflow drain voltage when smear is read by a vertical drive section to an overflow drain voltage lower than an overflow drain voltage when a still picture is read. With the above arrangement, there are provided a read controller for an image pick-up device, which can read out a sufficiently large amount of saturated charges from the image pick-up device by suppressing a decrease in an amount of saturated charges even if a voltage fluctuation occurs due to smear read-out, and an image pick-up apparatus that can obtain an image of excellent quality.
