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.

The invention belongs to the field of LED display, and in particular relates to an LED screen cover with transparent round holes formed by multi-layer periodically changing black nets.
