A method and device for an object detectable and background removal and storage media for storing program thereof enable automatic detection of an object to be executed minutely and high precisely for outline. A sectional image statistic calculation measure calculates a mean value and standard deviation of characteristic value of brightness and so forth of the sectional image with input image being subjected to division processing into sectional image. A background sectional image selection measure causes a sectional image whose standard deviation is the smallest value in the sectional images to be taken as the sectional image with high probability of including only the background. A background statistic estimation measure investigates the sectional image including only the background and another sectional image under the relationship between the mean value and the standard deviation. This investigation is implemented in terms of whole sectional images, a threshold generation object detectable and background removal measure discriminates the background and the detected target object based on predetermined calculation procedure. For instance, a second threshold is in use, which is obtained in such a way that the standard deviation multiplied by constant number given beforehand from the mean value is added thereto.
