Moving Object Noise Elimination Processing Device and Moving Object Noise Elimination Processing Program

A moving object noise elimination processing device comprising:

• a fixed imaging device that shoots an object to be imaged with a moving object in front thereof as an image frame;
• a memory that stores a plurality of the shot image frames in correlation with time series of the shooting;
• and
• a processing means that processes the shot image frames;
• and
• an output means that outputs an image frame processed based on a predetermined update criterion,
• the processing means comprising:
• a means that reads a plurality of image frames from the memory,
• a means that generates a luminance value frequency distribution for each of corresponding pixels for a plurality of the read image frames,
• a noise elimination complementing means that eliminates pixel data having luminance values other than the luminance value of the highest frequency in the luminance value frequency distribution for each of the pixels for which the luminance frequency distributions are generated and that uses pixel data having the luminance value of the highest frequency to complement the pixel having the pixel data eliminated.

A moving object noise elimination processing device comprising:

• two fixed imaging devices that shoot an object to be imaged with a moving object in front thereof as image frames, the two fixed imaging devices being arranged with a separation distance from each other such that the positions of the object to be imaged in the respective shot image frames are mismatched within arbitrarily predefined pixels in the image frames;
• a memory that stores the two respective image frames shot by the fixed imaging devices;
• and
• a processing means that processes the shot image frames;
• and
• an output means that outputs an image frame processed based on a predetermined update criterion,
• the processing means comprising:
• a means that reads two image frames shot at the same time by the fixed imaging devices from the memory,
• a means that compares luminance values of corresponding pixels of two image frames between the two read image frames,
• a noise elimination complementing means that eliminates pixel data having a higher luminance value as a noise for each of pixels of the two image frames compared in terms of the luminance values and that uses pixel data having a lower luminance value to complement the pixel having the pixel data eliminated.

A program outputting an image frame processed based on a predetermined update criterion after executing a moving object noise elimination process by shooting an object to be imaged with a moving object in front thereof as an image frame with a fixed imaging device and by processing the shot image frame on a computer, the program operable to drive the computer to execute:

• a processing step of reading an image frame shot at a time before the current time from a memory that stores an image frame shot by the fixed imaging device in correlation with time of the shooting;
• a processing step of comparing luminance values of corresponding pixels of two image frames between one read image frame and one image frame shot at the current time;
• and
• a noise elimination complementing step of eliminating pixel data having a higher luminance value as a noise for each of pixels of the two image frames compared in terms of the luminance values and using pixel data having a lower luminance value to complement the pixel having the pixel data eliminated.
