Provided is a moving image coding device capable of executing coding processing including stable rate control processing at high speed without greatly increasing computation amount. A moving image coding device 10 is provided with: a quantization unit 11 that quantizes image data constituting an image to be coded using a plurality of quantization parameters on a quantization-parameter-by-quantization-parameter basis; a storage unit 12 that stores a plurality of pieces of quantized image data in association with the quantization parameters used at the time of quantization; an extraction unit 13 that extracts, from the storage unit 12, predetermined quantized image data using a predetermined quantization parameter; a coding unit 14 that codes the extracted predetermined quantized image data; and a determination unit 15 that on the basis of the result of coding by the coding unit 14, determines a predetermined quantization parameter used when the extraction unit 13 next extracts predetermined quantized image data. |
