A moving image processing device (200) includes a face detector (3) (specific target detector), a compression ratio controller (4), and a quantizer (9) (video compressor). The face detector (3) detects a person's face included in an input image and extracts a face region. The compression ratio controller (4) generates and outputs a compression control instruction for reducing the compression ratio of the face region extracted by the face detector (3) so that a degree of reduction in the compression ratio of the face region is small in the case where the ratio of the area of the face region to the entire area of the input image is relatively large and so that the degree of reduction in the compression ratio of the face region large in the case where the ratio of the area of the face region to the entire area of the input image is relatively small. The quantizer (9) performs a quantization processing of the face region according to the compression control instruction given from the compression ratio controller (4).
