摘要： A scanning circuit operates at a driving speed approximately twice the conventional speed when clock signals having the same frequency as those in the prior art are supplied. By alternately driving the switches in even-numbered and odd-numbered transfer stages T1 to Tn, the input side and the output side of each transfer stage are simultaneously made high in order of T1, T2, . . . and Tn. Logical AND circuits are connected to the even- and odd-numbered stages to output pulse signals for scanning at intervals shorter than the clock period.

摘要： In a solid-state image-sensing device, when an image sensing operation is performed in each pixel, a MOS transistor T1 is turned on and a MOS transistor T4 is turned off to make a MOS transistor T2 operate in a subthreshold region. When a reset operation is performed in each pixel, the MOS transistor T1 is turned off and the MOS transistor T4 is turned on to feed a constant voltage to the gate and drain of the MOS transistor T2. Then, the MOS transistor T4 is turned off, then the voltage at the node “a” is reset, and then a pulse signal φV is fed to a MOS transistor T5 to obtain an output. By using the thus obtained output as compensation data, variations in sensitivity among individual pixels are reduced.

摘要： In a solid-state image-sensing device, first a switch Swa is turned on to sample and hold an image signal in a capacitor Ca, and then the switch Swa is turned off. Next, a switch SWb is turned on to sample and hold a noise signal in a capacitor Cb, and then the switch SWb is turned off. Next, switches SW1a and SW2a are turned on simultaneously so that the image signal in the capacitor Ca is fed through a buffer 6 to a capacitor Cc, and then the switches Sw1a and Sw2a are turned off. Then, a switch SW3 is turned on to reset the input side of the buffer 6. Next, switches SW1b and SW2b are turned on simultaneously so that the noise signal in the capacitor Cb is fed through the buffer to a capacitor Cd, and then the switches SW1b and SW2b are turned off. Then, the switch SW3 is turned on to reset the input side of the buffer 6 again.

摘要： A comparison section includes an analog signal to be subjected to AD conversion to a reference signal that increases or decreases with the passage of time, and terminates a comparison process at a timing at which the reference signal has satisfied a predetermined condition for the analog signal. A first count section counts a clock signal of a predetermined frequency as a count clock and outputs a count value. A latch section latches the count value output from the first count section. A latch control section enables the latch section at a first timing related to an end of the comparison process and causes the latch section to execute a latch operation at a second timing delayed by a predetermined time from the first timing.
