Title:
Video coding equipment, its control method, and an imaging device
Document Type and Number:
Japanese Patent JP6239838
Kind Code:
B2
Abstract:
There is provided a moving image encoding apparatus configured to perform encoding using motion compensation and quantization. A first dividing unit divides a coding target image into a plurality of first block images. A second dividing unit divides the first block image into a plurality of second block images. A characteristic amount calculating unit calculates, for each of the plurality of second block images, a characteristic amount. A selecting unit, if a degree of variation in the characteristic amounts of the plurality of second block images is greater than or equal to a threshold value, selects the plurality of second block images, and if not, selects the first block image. An encoding unit encodes the plurality of second block images or the first block image in accordance with the selection performed by the selecting unit.
