Abstract:
A photograph printing device comprising:a light modulation element, provided with a plurality of pixels, for controlling supply of light to a photosensitive material through each pixel in accordance with image data;a light source for irradiating light to said light modulation element; andlight irradiation control means for generating more than one beam of light, each having a different optic axis, from incident light through a particular pixel in said light modulation element, and for irradiating each of generated beams of light to said photosensitive material;wherein said light irradiation control means generates, from the incident light through said particular pixel in said light modulation element, a beam of light having an optic axis different from an optic axis of the incident light, and irradiates said generated beam of light to said photosensitive material at different irradiation positions; andwherein said light irradiation control means includes a refracting member that is rotateable about the optic axis of the incident light or an axis parallel to the optic axis for refracting light incident thereon; and said refracting member is allowed to rotate so as to irradiate refracted light to said photosensitive material at different irradiation positions.
