The present study was aimed to develop analysis method of relationship between instantaneous heart rate (IHR) and amount of movements in newly hatched chicks in order to investigate the origin of heart rate fluctuation. The measured image was separated into the three primary colors (R, G, B), and then the image of the green component which is the most noiseless was used for calculation of the amount of movements. The difference of the pixel values between two adjacent frames was quantified sequentially. After adequate threshold level was determined, the image was binarized to divide into black and white pixels. The number of the white pixels was quantified as the amount of body movements. In addition, we attempted to apply this analysis method to the images under some light conditions. As a result, the amount of movements could be calculated from the color image and the only one threshold level could be determined in the case of having some changes in light conditions. In the further study, the relationship between IHR and the amount of movements in long term measurement will be possible to examine in detail by the present analysis system.
