信号处理单元、固态摄像单元、电子装置、信号处理方法和记录媒介
摘要：
本发明公开了信号处理单元、固态摄像单元、电子装置、信号处理方法和记录媒介。所述信号处理单元包括：提取部，其被构造用来提取多个采样值之间的变化量，所述多个采样值是通过对在第一状态和第二状态的一者或两者中的信号电平的多个采样操作而获得的，所述第一状态是浮动扩散部被复位的状态，所述浮动扩散部临时累积从进行光电转换的光电二极管传输来的电荷，且所述第二状态是所述光电二极管中生成的电荷累积在所述浮动扩散部中的状态；和比较部，其被构造用来将所述提取部提取的所述变化量与预定的基准值进行比较，并且被构造用来根据比较的结果切换将被输出至后级的处理部的信号。根据本发明，能够获取更加适于降噪处理的信号。
摘要（英）：

The present invention discloses a signal processing unit, a solid-state image pickup unit, an electronic apparatus, a signal processing method, and a recording medium. The signal processing unit includes: an extraction section configured to extract variation between a plurality of sampling values obtained through a plurality of sampling operations of signal levels in one or both of a first state and a second state, the first state being a state where floating diffusion is reset, the floating diffusion temporarily accumulating charges transferred from a photodiode performing photoelectric conversion, and the second state being a state where charges generated in the photodiode are accumulated in the floating diffusion; and a comparison section configured to compare the variation extracted by the extraction section and a predetermined reference value, and to switch, based on a result of the comparison, a signal to be output to a processing section in a subsequent stage. According to the signal processing unit, a signal more suitable for noise reducing processing is obtained.
