Abstract
An image encoding device and an image encoding method to be used therein can reduce generated code amount for permitting assignment of large coding amount to a portion where the most significant variation is caused, and whereby improvement of image quality is realized. The device performs image encoding by determining a motion vector amount of an image. The device makes judgment whether a motion vector amount calculated by using a preliminarily set difference threshold value can be replaced with a motion vector amount one preceding macro block.
Claims15
An image encoding device for performing image encoding by determining a motion vector amount of an image comprising:
- judgment processing means for processing judgment whether a motion vector amount calculated by using a preliminarily set difference threshold value can be replaced with a motion vector amount one preceding macro block.
An image encoding method for performing encoding of an image for determining a motion vector amount of said image comprising a step of:
- processing judgment whether a motion vector amount calculated by using a preliminarily set difference threshold value can be replaced with a motion vector amount one preceding macro block.
A storage medium storing a program for making a computer to execute an image encoding process for encoding of an image for determining a motion vector amount of said image comprising a step of:
- processing judgment whether a motion vector amount calculated by using a preliminarily set difference threshold value can be replaced with a motion vector amount one preceding macro block.
