Solid-state imaging device
摘要:
In the case where a subject is captured with a high-luminance light, such as sunlight, for a background, a phenomenon that a portion of the high-luminance subject is detected as a no-signal level is prevented. The solid-state imaging device includes: a photoelectric transducer PD which converts incident light to charges; a voltage level detection circuit 50 in which pixel units 10an1 and 10bn1, each having a voltage conversion amplifying transistor Q13a which outputs a voltage by converting the charges accumulated in the photoelectric transducer PD, are arranged one-dimensionally or two-dimensionally, and which detects a pixel output voltage outputted from each of the pixel units to the common column signal line Ln; and a column signal processing circuit 80 which receives a logic output voltage of the voltage level detection circuit 50 and the pixel output voltage and which outputs a voltage to a horizontal output circuit 90. The column signal processing circuit 80 outputs either a voltage identical to the pixel output voltage or a fixed voltage, depending on the logic output voltage.
