摘要： A signal SG41 that has color signals thereof time-sequentially arranged in a color array corresponding to the color array in an image sensor 3 and that has not undergone resolution conversion is subjected to resolution conversion at a conversion rate (for example, ⅓) specified by a phase retention resolution conversion section 42. A de-mosaicing processing section 44 converts a signal SG42, which represents the order of the color array in the image sensor, into RGB signals SG44. A thin-line retention resolution conversion section 45 converts the signals SG44 into signals SG45 at a specified conversion rate (for example, ½). The signals SG45 are compressed by an encoder. In a recording medium 9, YC signals SG48 representing (640×480) pixels, the color signals SG42, a signal SG51 representing (640×480) pixels in the order of a color array and serving as thumbnail image data DT, and imaging information are recorded.
