Abstract: The present disclosure relates to an image encoding apparatus that makes it possible to improve the encoding speed while maintaining the image quality. A statistical information calculation unit supplies calculated statistical information to a table selection unit. Further, a picture type of an image from a screen rearrangement buffer and a quantization parameter Qp from a rate control unit are supplied to the table selection unit. The table selection unit determines a mode table to be used from a plurality of mode tables stored in a table storage unit on the basis of the statistical information and the picture type. For example, the table selection unit selects the mode table according to whether the statistical information is larger or smaller than a predetermined threshold. The present disclosure can be applied to, for example, an image processing apparatus that performs encoding.
