Patent ID: 7391454

Claim:
An image sensor controller that controls an image sensor having a light receiving section and a transfer section that receives data signals from the light receiving section, the image sensor controller comprising: a drive controller configured to supply a shift/transfer clock to the transfer section, the shift/transfer clock used for shifting the data signals and transferring the data signals; the shift/transfer clock being configured to have a first frequency during a first period in which a first data signal of the data signals is outputted from a dummy pixel of a plurality of pixels included in the light receiving section, wherein the dummy pixel is light-shielded; the shift/transfer clock being configured to have a second frequency during a second period in which a second data signal of the data signals is outputted from a non-reading pixel of the plurality of pixels; the shift/transfer clock being configured to have a third frequency during a third period in which a third data signal of the data signals is outputted from a reading pixel of the plurality of pixels; the first frequency being higher than the second frequency; and the second frequency being higher than the third frequency.
