摘要： In a solid-state imaging device meeting color image pickup, which an AD converter is mounted on the same chip, the circuit scale and the number of transmission signal lines are reduced and a reference signal suitable for color image pickup is fed to an AD conversion comparing portion. DA converter circuits for two pixels of a repeat unit of a separation filter in the horizontal row direction in a unit of readout are prepared as a functional portion to generate a reference signal for AD conversion. The DA converter circuits generate the reference signals having a tilt in accordance with a color property and varying from an initial value based on a non-color property such as a black reference and a circuit offset. Each reference signal independently outputted from the DA converter circuits is basically directly transmitted through common signal lines to a voltage comparing portion which corresponds to color filters having a common color property through independent signal lines.

摘要： In a solid-state imaging device with an AD converter mounted on the same chip, to enable an efficient product-sum operation while reducing the size of the circuit scale and the number of transmission signal lines. A pixel signal during an n-row readout period is compared with a reference signal for digitizing this pixel signal, and a counting operation is performed in one of a down-counting mode and an up-counting mode while the comparison processing is being performed, and then, the count value when the comparison processing is finished is stored. Subsequently, by using the n-row counting result as the initial value, a pixel signal during an (n+1)-row readout period is compared with the reference signal for digitizing this pixel signal, and also, the counting operation is performed in one of the down-counting mode and the up-counting mode, and then, the count value when the comparison processing is finished is stored. If the count mode for the n+1 row is set to be opposite to the count mode for the n row, the count value obtained by the counting operation for the n+1 row is a subtraction result. If the count modes for the n+1 row and the n row are set to be the same, the count value obtained by the counting operation for the n+1 row is an addition result.

摘要： A column analog-to-digital converter having a voltage comparator and a counter is arranged for each a vertical signal line. The voltage comparator compares a pixel signal inputted via the vertical signal line at each row control signal line with a reference voltage, thereby generating a pulse signal having a length in time axis corresponding to the magnitude of a reset component and a signal component. The counter counts a clock to measure the width of the pulse signal until the end of the comparison operation of the comparator, and stores a count at the end of the comparison. A communication and timing controller controls the voltage comparator and the counter so that, in a first process, the voltage comparator performs a comparison operation on a reset component with the counter performing a down-counting operation, and so that, in a second process, the voltage controller performs the comparison operation on a signal component with the counter performing an up-counting operation.
