Pixels, a charge storage element, a comparison signal generator that generates comparison signals, and a first analog-to-digital converter circuit that performs analog-to-digital conversion are included. The comparison signal generator generates the comparison signals such that a waveform having a voltage value that ranges from an upper limit to a lower limit and that has linearity and continuity is formed by connecting waveforms of the comparison signals to each other.

Solid-state imaging device with high resolution A/D conversion

There is provided a solid-state imaging apparatus including a driving device that reads image data from an imaging unit. When reading the image data from the imaging unit, the driving device renders the image data composed of image data having V rows and H columns and blanking data having V' rows and H&#x2032; columns, and renders the amount of the image data changeable for at least every one frame.

Solid-state imaging apparatus

A self-synchronous FIFO memory device () has a structure in which n self-synchronous data transmission lines (-) are arrayed in parallel. An input control section () selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a first transfer request signal, a first acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a preceding-stage section. Further, an output control section () selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a second transfer request signal, a second acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a succeeding-stage section.
