Abstract
A picture encoding method employed in a system for encoding video signals of a motion picture for storage on a picture recording medium or in a system employed for transmitting video signals of a moving picture over a transmission channel. The encoding method includes a first step of generating the information on picture characteristics at least including the luminance information of the input video signals in terms of a pre-set time interval as a unit, a second step of calculating the information on the amount of generated bits of the information on picture characteristics in terms of a pre-set time interval as a unit, a third step of determining an encoding bit rate, based upon the information on picture characteristics, the information on the amount of the generated bits and the information on the total amount of data usable during transmission of encoded data, in terms of the pre-set time interval as a unit, and a fourth step of encoding the input video signals in accordance with the encoding bit rate in terms of the pre-set time as a unit for generating the encoded data.
