Provided is an image processing device that removes noise caused by disturbance during image capture from a captured image by image processing, the image processing device includes an image input unit to which a plurality of temporally continuous captured images are input, an image feature extraction unit that extracts features related to the disturbance in the captured images, and an image sharpening unit that performs image processing based on the features related to the disturbance to thereby remove noise in the captured images. Further, the image processing device may further include mode switching means for switching between a monitoring mode for performing image processing based on the features related to the disturbance and a normal mode for preventing the image processing based on the features related to the disturbance from being performed.

Image processing device, monitoring system provided with same, and image processing method

To increase the processing speed when median processing in the time direction is performed on color images, pixel values of each channel (R, G and B values) are extracted from multiple temporally consecutive frame images; subsequently, identifiers (index numbers) corresponding to frame images from which the pixel values are extracted are assigned to the pixel values; subsequently, a sorting process is performed on a set of pixel values of one channel (G values) to obtain an identifier assigned to a median value thereof; subsequently, a pixel value to which an identifier identical with that assigned to the median value is assigned is selected as a median value of each channel; and subsequently, a median image is generated on the basis of the median value of each channel obtained for each pixel.

Image processing device and image processing method

A surveillance recorder () comprises: a picture input unit () for inputting a surveillance picture; a moving object detection unit () for detecting a moving object from a surveillance picture inputted by the picture input unit (); a face image detection unit () for detecting, from an object detected by the moving object detection unit (), a part having an elliptical outline as a face image; an identity judgment unit () for judging whether a face image newly detected by the face image detection unit () is of a same person as a face image detected last time or not based on positions of each face image; a storage image choice unit () for, when a newly detected face image has been judged to be of a same person by the identity judgment unit (), choosing one face image from a face image of the same person stored in a recording medium () and the newly detected face image; and an image storage unit () for, when a newly detected face image has been chosen by the storage image choice unit (), storing in the recording medium () both the newly detected face image and information for searching for the face image together. This allows an image suitable for storage to be detected from a surveillance picture.
