摘要： Disclosed is a horizontal transfer line in which first horizontal transfer pulses are applied to transfer electrodes via a commonly connected electrode line, second horizontal transfer pulses are applied to transfer electrodes via a commonly connected electrode line, and final horizontal transfer pulses are applied to a final transfer electrode via an electrode line independent of the above-mentioned electrode lines. Since the independent electrode line is independent of the other electrode lines, amount of capacitance produced in equivalent terms is reduced. The final transfer pulses exhibit a steep characteristic, thereby improving transfer efficiency. The input/output characteristic of the horizontal transfer line is improved as a result.

The pixel cell according to embodiments of the invention includes a photo-conversion device and a floating diffusion region switchably coupled to the photo-conversion device. The pixel cell includes a reset transistor, which has a first terminal electrically connected to the floating diffusion region and a second terminal switchably coupled to first and second voltage sources. The first voltage source is higher than the second voltage source. The pixel cell operates by returning a potential on the photo-conversion device to a value approximately equal to a value of a potential barrier between the photo-conversion device and the floating diffusion region prior to generating charge in the photo-conversion device.

摘要： A digital camera feeds information input on an operation panel to a system controller. The system controller generates a control signal in accordance with optical sensitivity selected and feeds it to a timing signal generator. The timing signal generator includes a signal generator, which generates a timing signal whose frequency matches with the control signal. While a solid-image image sensor is driven by the timing signal, the frequency of a horizontal transfer signal is made lower than the usual frequency in accordance with the sensitivity selected. This prevents the number of electrons from noticeably decreasing during horizontal transfer to thereby enhance transfer efficiency for a single stage of transfer.
