Title:
ENCODED AUXILIARY INFORMATION GENERATION DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2023114388
Kind Code:
A
Abstract:
To find encoding difficulty with high accuracy.SOLUTION: A coding auxiliary information generating device 1 includes a coding information extracting unit 11 that performs coding processing on an original image and extracts information on a quantization parameter and a motion vector used for coding for each coding block, and an encoding difficulty calculation unit 12 that calculates encoding difficulty for each encoding block position by weighted addition of first encoding difficulty based on the value of the quantization parameter and second encoding difficulty based on a magnitude and variance of the motion vector.SELECTED DRAWING: Figure 1
