This type of CCD sensor uses two sections: a light-sensitivepixel area(Image Section) and a shaded area (shaded parallel register) to store the acquired charge(Store Section). During exposure, photons in the pixels release a charge that is immediately transferred to the parallel shaded section of the sensor. Here, a "slow" readout of the acquired charge takes place, whereas a new exposure can take place again in the pixel section. The acquisition speed (in ms) is higher than that of a full-frame CCD, and the acquisition can take place in parallel with the readout. The disadvantages are smearing (blurring) occurring when moving the charge between two parts of the sensor and the larger size of the chip.
