    • A solid imaging apparatus and the analog-to-digital converting method and photographing apparatus of the solid imaging apparatus are provided to implement faster analog-to-digital conversion without being limited by the working speed of a counter unit. A comparison unit converts the size of a pixel signal into information of a time-axis direction by comparing a reference signal and an analog pixel signal for converting into digital data. A counter unit performs counting according a predetermined clock from the start point of time of the comparison process to the end point of time of the comparison process in the comparison unit. A multi-phase clock generation unit generates a multi-phase clock having a fixed phase difference according to the predetermined clock. A latch unit latches the logic state of the multi-phase clock when the comparison process at the comparison unit was completed. A decode unit decodes the latch data of the latch unit and obtains a value lower than a count value by the counting.
    • 提供固体成像装置和固体成像装置的模数转换方法和拍摄装置,以实现更快的模数转换,而不受计数器单元的工作速度的限制。 比较单元通过比较参考信号和用于转换为数字数据的模拟像素信号,将像素信号的尺寸转换为时间轴方向的信息。 计数器单元从比较处理的开始时刻到比较处理的结束时刻,按照规定的时钟进行计数。 多相时钟产生单元根据预定时钟产生具有固定相位差的多相时钟。 当比较单元的比较处理完成时,锁存单元锁存多相时钟的逻辑状态。 解码单元解码锁存单元的锁存数据,并通过计数获得低于计数值的值。
