Thermal compensation in image projection
Apparatus for controlling a spatial light modulator (106) of an image projector (100), the image projector further comprising an illumination source (102) arranged to illuminate the spatial light modulator (106), the apparatus comprising an input (126) for receiving image data, an output for outputting image data and a controller (110) in communication with the input and the output, the controller (110) being configured to: determine an estimated thermal state of the projector; use at least the estimated thermal state of the projector to obtain an expected illumination pattern of light incident on the spatial light modulator (106) when illuminated by the illumination source (102); use the expected illumination pattern to adjust the received image data so as to compensate for thermal changes in one or more components of the image projector; and output the adjusted image data to the spatial light modulator (106).
Instant film pack and device using the same
The film cover constituting the instant film pack includes a cover member, a pair of accompanying prevention ribs, a pair of outer light shielding ribs, and a pair of inner light shielding ribs. The accompanying prevention ribs are arranged in parallel with a discharge direction from a distal end of the film cover in the discharge direction. Similarly to the accompanying prevention ribs, since the outer light shielding ribs are formed on a front surface of the cover member, the outer light shielding ribs together with the accompanying prevention ribs can prevent the film unit from accompanying. A tilt surface of which a protruding height gradually decreases toward a distal end from a proximal end of the cover member is formed on the accompanying prevention rib.

Overlay control with non-zero offset prediction
A process control system may include a controller configured to receive after-development inspection (ADI) data after a lithography step for the current layer from an ADI tool, receive after etch inspection (AEI) overlay data after an exposure step of the current layer from an AEI tool, train a non-zero offset predictor with ADI data and AEI overlay data to predict a non-zero offset from input ADI data, generate values of the control parameters of the lithography tool using ADI data and non-zero offsets generated by the non-zero offset predictor, and provide the values of the control parameters to the lithography tool for fabricating the current layer on the at least one production sample.
Automatic detection of panoramic gestures
Aspects of the disclosure relate to capturing panoramic images using a computing device. For example, the computing device may record a set of video frames and tracking features each including one or more features that appear in two or more video frames of the set of video frames within the set of video frames may be determined. A set of frame-based features based on the displacement of the tracking features between two or more video frames of the set of video frames may be determined by the computing device. A set of historical feature values based on the set of frame-based features may also be determined by the computing device. The computing device may determine then whether a user is attempting to capture a panoramic image based on the set of historical feature values. In response, the computing device may capture a panoramic image.

Image forming device
An image forming device includes: element arrays each including light emitting elements arranged in main scanning direction, the arrays being arranged in sub scanning direction; a photoreceptor whose surface moves relative to the light emitting elements in the sub scanning direction; a controller outputting control voltage instructing light emission amount for each light emitting element; and drivers each supplying drive current to a corresponding light emitting element according to the control voltage, thus causing the light emitting element to emit light to expose the moving surface of the photoreceptor. Intervals L between the arrays satisfy (D/2)(V/F)((V/F)0.1)L(D/2)(V/F)+((V/F)0.1) where F expresses frequency of AC noise to be superimposed on the control voltage, V expresses system speed of the surface of the photoreceptor moving relative to the light emitting elements, and D is an odd number.

PRINTER, PRINTER-EQUIPPED IMAGING APPARATUS, AND PRINTING CONTROL METHOD
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.
PRINTER AND DIGITAL CAMERA INCLUDING PRINTER
A digital camera including a printer includes a transport roller pair that transports an instant film, an exposure unit that exposes an image onto the instant film, a spreading roller pair that spreads a developer into a gap of the instant film by crushing a developer pod of the exposed instant film, a spreading control member that is positioned between the transport roller pair and the spreading roller pair, extends in a width direction of the instant film, and controls the developer spread into the gap, and a mechanical switch that is positioned near the spreading control member.
