Abstract: A printing device includes: a substrate feed-out section; a substrate transport section; a storage which stores the width size of the substrate; a skew correction section including a skew sensor which detects the skew of the substrate, and adapted to correct the skew of the substrate with reference to an output of the skew sensor and the substrate width size stored in the storage; an image recording section which performs an image recording operation on the substrate; a first sensor which detects a width size-changed portion of the substrate upstream of the skew correction section with respect to the transport direction; and a controller. Upon the detection of the width size-changed portion, the controller stops the substrate skew correction while continuously transporting the substrate. After the width size-changed portion of the substrate reaches a reference position downstream of the skew correction section, the controller restarts the skew correction.

Abstract: A printing system includes a coating device, a printing device, and a controller. The coating device applies a processing liquid to a base material by bringing a coating roller with the processing liquid adhering thereto into contact with the transported base material. The printing device performs printing on a surface of the base material to which the processing liquid has been applied. The controller includes a contact-start-position identifier, an inappropriate-printing-area setter, and a print controller. The contact-start-position identifier identifies a contact start position of the base material in which the coating roller and the base material start to come in contact with each other. The inappropriate-printing-area setter sets, as the inappropriate printing area, an area of the base material that has a predetermined length in a transport direction from the contact start position. The print controller stops the printing device from performing printing on the inappropriate printing area.

Abstract: An image signal processing device receives image signals from source devices and outputs image signals via a plurality of communication paths. The image signal processing device includes a plurality of compression circuits, a transmission circuit and a path/compression-rate setting circuit. The plurality of compression circuits compress image signals to be transmitted via the plurality of communication paths. The transmission circuit outputs the image signals compressed. The path/compression-rate setting circuit, based on each data amount of the image signals received, determines a communication path for transmitting a part or the whole of each of the image signal, and sets a common compression rate for all of the plurality of compression circuits. The path/compression-rate setting circuit divides an image signal having a relatively large data amount, and assigns a part of the divided image signal to a communication path for transmitting an image signal having a relatively small data amount.

Abstract: A projection type image display apparatus includes an adjusting sub-frame image generator and a shift amount adjuster. The adjusting sub-frame image generator generates a primary adjusting sub-frame image having a design in which a first line having a first color and a width of an N pixel (N being a natural number) is displayed on a background image having a second color, and a secondary adjusting sub-frame image having a design in which a second line having a third color and a width of an M pixel set to N=M+? (M being an integer equal to or greater than 1, ? being an integer equal to or greater than 0) is displayed on a background image having a fourth color. The shift amount adjuster adjusts the shift amount when the display positions of the primary and secondary adjusting sub-frame images on the projection surface are shifted relatively to each other.
