    摘要： The present invention discloses a color rolling detection method and detection device for an input image, which can detect a phenomenon of color rolling in the image rapidly, efficiently and at a low cost. The detection method includes the steps of: an extracting step for extracting parameter values indicative of the color or brightness of the image in a detection time period T3; a preprocessing step for performing a preprocess to the extracted parameter values so as to obtain characteristic values of the image; an initial value setting step for obtaining a first initial value from the characteristic values in an initialization time period of the detection time period T3; an average value calculating step for calculating, with respect to each detection cycle T2 in the detection time period T3, an average value on the time axis of the characteristic values in the detection cycle T2 based on the obtained first initial value; and a detecting step for detecting whether there exists in the detection time period T3 such a detection cycle T2 that the characteristic values in the detection cycle T2 always maintain a deviation in a specific direction relative to the average value thereof, wherein if so, then occurrence of the color rolling is judged; otherwise, no occurrence of the color rolling is judged.

    摘要： An imaging device that includes a control unit is provided. The control unit switches between a day mode and a night mode. In the day mode, image capture is performed while an infrared cut filter is placed on an optical path, and in the night mode, image capture is performed while the infrared cut filter is removed from the optical path. Immediately after shifting from the day mode to the night mode, in the night mode, as the amount of incident light decreases, the control unit increases an irradiation intensity of an infrared irradiation portion from zero while a gain is maintained at a first gain value. When the amount of the incident light further decreases after the irradiation intensity reaches a maximum, the control portion increases the gain from the first gain value.
