Abstract: An image projection apparatus (100) displays includes a lens attachable portion (170) to which a plurality of projection lenses (160a, 160b, 160c) having different optical characteristics are interchangeably attached, a drive signal producer (130) configured to produce, for each color light beam, a drive signal used to drive the light modulation element based on an input image signal, and an information acquirer (132) configured to acquire information on an optical characteristic of the projection lens attached to the lens attachable portion. The information on the optical characteristic of the projection lens contains information on a chromatic aberration of the projection lens. The drive signal producer reduces influence of a shift below the modulation pixel caused by the chromatic aberration of the projection lens by using the information on the optical characteristic.

Abstract: The present invention provides an imaging system of a photo-curing 3D printing device. The imaging system comprises a light source, a liquid crystal panel, a first polarized light filter, a second polarized light filter, a focusing lens array, a projection lens, and a controller. The imaging system is characterized in that the focusing lens array is disposed on a light incoming side of the liquid crystal panel; each focusing lens of the focusing lens array is corresponding to each pixel of the liquid crystal panel; each focusing lens can gather light beams irradiating to the corresponding pixels, so that the light beams penetrate a light transmission region of the pixels as much as possible. A deflection lens is arranged on a light outgoing side of the liquid crystal panel; the deflection lens can deflect around at least one rotation axis perpendicular to an optical axis of the imaging system, so as to finely tune positions of images of the light beams projected to the surface of a light-sensitive material. The controller commands the light source to expose for multiple times and commands the deflecting lens to deflect in exposure each time, so as to project the images of the light beams exposed each time to different positions of the surface of the light-sensitive material.

Abstract: A printing machine includes a movable lens, which may be placed in position at the time of printing and held at a stand-by position spaced apart from a film during other operations. In this way, maintenance and adjustment of the lens become easy. A sample print monitor comprising a CCD camera, a line sensor, etc., is provided for measuring deviation of the center of exposure to automatically register correction values. A desired exposure angle is obtained by rotating a negative mask portion, a lens portion, an exposure table, etc., at the same angle. In addition to a rotary mechanism, the lens portion is slid finely so as to constitute a printing machine of a three-dimensional photograph having higher accuracy. Moving means are provided to an enlarging lens and to the exposure table so as to effect printing by trimming. An edge shaver is caused to act in a rectangular direction to the travelling direction of printing paper so as to cut off dust within the range of the end surface of the tip of printing paper cut by a cutter, and the dust is sucked by a dust suction mechanism and is sent to a dust box.
