FRAME RATE CONTROL METHOD, FRAME RATE CONTROL DEVICE, AND FRAME RATE CONTROL PROGRAM

摘要

An object is to suppress an instantaneous increase in the computational complexity of an encoder and an information amount of an encoding result without increasing a delay even when input timing of input video is not constant and fluctuates. A frame rate control method for adjusting a frame rate of input video to a frame rate at which an encoder is able to perform encoding includes: a step of determining whether the number of pictures input in the past within a predetermined time from a time when a determination target picture of dropping is input exceeds a predetermined threshold value; and a step of discarding the determination target picture if the number of pictures exceeds the threshold value and designating the determination target picture as an encoding target if the number of pictures does not exceed the threshold value.
