Disclosed herein is an image processing apparatus including: a detection section configured to detect a motion area in a screen based on images taken, and output detection information; an accumulation section configured to accumulate the detection information for the past as outputted from the detection section; an area division section configured to divide the screen into an area where motions regularly occur and a motion-free area, based on the detection information for the past as accumulated in the accumulation section, and output area information; and an alarm management section configured to perform particular control based on the area information from the area division section and the detection information from the detection section.

Image processing apparatus, image apparatus, image processing method, and program for analyzing an input image of a camera

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 T; 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 T; an average value calculating step for calculating, with respect to each detection cycle Tin the detection time period T, an average value on the time axis of the characteristic values in the detection cycle Tbased on the obtained first initial value; and a detecting step for detecting whether there exists in the detection time period Tsuch a detection cycle Tthat the characteristic values in the detection cycle Talways 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.
