The disclosure of the present invention relates to an image encoding device and method by which it is possible to improve encoding speed while maintaining image quality. A statistical information calculation unit supplies calculated statistical information to a table selection unit. The table selection unit is additionally supplied with a picture type of an image from an image reordering buffer, and a quantization parameter Qp from a rate control unit. The table selection unit determines which of a plurality of mode tables stored in a table memory unit to use on the basis of the statistical information and the picture type. For example, the table selection unit selects the mode table depending on factors such as whether the statistical information is greater or less than a prescribed threshold value. This disclosure can be applied to an image processing device that performs encoding, for example. |
