The method performs prediction of the pixel value of the encoding target and obtains the predicted value; computes data of a probability distribution which indicates what value an original pixel value has for the obtained predicted value, by shifting, in accordance with the predicted value, difference distribution data of a difference between the original pixel value and the predicted value in predictive encoding, where the difference distribution data is stored in advance; clips the obtained data of the probability distribution so as to contain the data in a range from a lower limit to an upper limit for possible values of the original pixel value; and encodes the pixel value of the encoding target by using the clipped data of the probability distribution of the original pixel value from the lower limit to the upper limit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video encoding method and decoding method, apparatuses therefor, programs therefor, and storage media which store the programs","description":"An image encoding method for encoding a pixel value of an encoding target by using a predicted value generated by spatial or temporal prediction using a previously-decoded image.
