Abstract: A liquid ejecting apparatus includes an ejection unit that ejects a liquid, a medium support unit that has a support face supporting a medium to which the liquid is ejected, an irradiation unit that irradiates the medium with a first electromagnetic wave from an oblique direction with respect to the support face, and a sensor that detects a second electromagnetic wave which is emitted from an irradiation region of the first electromagnetic wave on the support face, in which the sensor is in a position with respect to the irradiation unit which is the same side as an irradiation direction of the first electromagnetic wave, and is arranged in a position where a regular reflection component of the first electromagnetic wave reflected at a peak spot where irradiation energy of the first electromagnetic wave peaks in the irradiation region is not detected.

Abstract: A method for preparing an article of lenticular imaging. The method comprises receiving a plurality of source images, superimposing at least one deghosting element on the plurality of source images, the deghosting element being formed to reduce an estimated ghosting artifact from the article, interlacing the plurality of processed source images so as to form a spatially multiplexed image, and preparing the article by attaching an optical element to the spatially multiplexed image.
