An image coding apparatus and method capable of suppressing a decrease in coding efficiency. The image coding apparatus includes: a coding unit that codes image data configured by plural layers; an interlayer prediction-related information generating unit that generates information relating to an interlayer prediction of the current slice in a case a layer of the current slice is an enhancement layer, and a slice type of current slice is a P slice or a B slice; and a transmission unit that transmits coded data of the image data generated by the coding unit and the information relating to the interlayer prediction generated by the interlayer prediction-related information generating unit. The apparatus and method, for example, may be applied to an image coding apparatus that scalably codes image data or an image decoding apparatus that decodes coded data acquired by performing scalable coding of the image data. |
