A printing system (100) comprising a projecting device (200) configured to project a digital content. The device (200) includes a memory (102) for storing instructions, a processor (104) coupled to the memory (102), an input unit (106) configured to receive at least one input corresponding to the digital content from a user, a digital content processing unit (110) configured to process the digital content, a sensing unit (112) configured to monitor an ambient environment conditions, and a projecting unit (114) configured to project the processed digital content; and a printable substrate (202) configured to receive and imprint the projected digital content from the projecting device (200).

A method for determining adjustment to a patterning process. The method includes obtaining a probability density function of a parameter related to a feature of a substrate subject to the patterning process based on measurements of the parameter, determining an asymmetry of the probability density function, and determining an adjustment to the patterning process based on the asymmetry of the probability density function of the parameter so as to reduce a probability of the feature having a parameter value that falls outside a range between threshold values of the parameter.

An exposure apparatus that projects a pattern of an original onto a substrate via a projection optical system and exposes the substrate is provided. The apparatus comprises an aberration correction member arranged on an optical path of exposure light between the original and the substrate, and a driver which drives the aberration correction member. The aberration correction member includes a first optical element including a first surface having a three-fold rotational symmetric aspherical shape with respect to an optical axis of the exposure light, and a second optical element spaced apart from the first optical element along the optical axis and including a second surface facing the first surface and having an aspherical shape that complementarily corrects an aberration generated by the first optical element.

A system is disclosed for the automated correction of optical and digital aberrations in a digital imaging system. The system includes several main parts, including (a) digital filters, (b) hardware modifications, (c) digital system corrections, (d) digital system dynamics and (e) network aspects. The system solves numerous problems in still and video photography that are presented in the digital imaging environment.

A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head and is used for detecting a transport speed of an instant film. The light exposure head sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit corrects an amount of light emission of the light exposure head depending on the transport speed of the instant film.

A light source module of a photo printer includes a first micro light source, a second micro light source, a rod lens array and a microlens. The first micro light source emits a first light beam. The second micro light source emits a second light beam. The rod lens array is arranged between the first micro light source, the second micro light source and a film paper. The microlens is arranged between the first micro light source, the second micro light source and the rod lens array. The microlens is used for converging the projection angles of the first light beams and the second light beam. The microlens has an optical axis. The second micro light source is arranged along the optical axis. The first micro light source is arranged beside a first side of the optical axis.

In a case that accommodates an instant film, an exposure opening portion, a discharge port, and a claw opening portion are provided. The exposure opening portion is light-shielded by a film cover that is disposed to overlap the instant film. The film cover includes a notched portion connected to the claw opening portion. In a case where the film cover is not removed in use, a claw inserted through the claw opening portion is moved within a range of the notched portion. In a case where the film cover is removed in use, the claw is moved within a range that exceeds the range of the notched portion.
