  • Moving picture encoding device and method of operating the same
    Patent number: 11683497
    Abstract: A video image encoding device includes: an image encoding unit that performs predictive encoding by obtaining a difference between a divided image included in a frame as a target of predictive encoding and a prediction image; local decode generation unit that decodes an encoding result of the divided image by the image encoding unit to generate a reference image; a first buffer that stores pixel data generated by the local decode generation unit; a compression unit that refers to the first buffer to compress the reference image and generates compressed data; an allowable data amount setting unit that presets an allowable data amount to be stored in the memory for each predetermined area of the frame as the target of the predictive encoding; and a reference image storage determination unit that determines whether the compressed data is store in the memory based on the allowable data amount, and stores the compressed data in the memory based on a determination result of storing the compressed data in the memory
