An information processing device includes an assistance image display and an assistance-image changing unit. The assistance image display causes a display section of a portable terminal provided with the display section and an image capturing section to display an assistance image for assisting with an operation of a target object be operated by an operator. The assistance-image changing unit changes the assistance image displayed on the display section by the assistance image display to a mode for not assisting with the operation of the target object in a case where a captured image result obtained by the image capturing section of the portable terminal satisfies a predetermined condition.

Systems, devices, media, and methods are described for capturing a series of video clips, together with position, orientation, and motion data collected from an inertial measurement unit during filming. The methods in some examples include calculating camera orientations based on the data collected, computing a stabilized output path based on the camera orientations, and then combining the video segments in accordance with said stabilized output path to produce a video composition that is stable, short, and easy to share. The video clips are filmed in accordance with a set of conditions called a capture profile. In some implementations, the capture profile conditions are reactive, adjusting in real time, during filming, in response to sensor data gathered in real time from a sensor array.

An image processing apparatus comprising a light emission control unit configured to control a mode of a light emitting unit configured to emit light, wherein the light emission control unit causes the light emitting unit to emit light in a color corresponding to a first mode when the image processing apparatus operates in the first mode upon receiving an instruction from a specific application.

An apparatus having a plurality of operation modes including at least a normal power mode and a power-saving mode in which power consumption is lower than that in the normal power mode comprises: a human sensor configured to detect a person who exists within a predetermined range of the apparatus; a communication unit configured to wirelessly communicate with external equipment that is held above the apparatus; a first guidance display unit configured to indicate a position where the external equipment is held above by lighting; and a control unit configured to control, in the case where the human sensor detects a person in the power-saving mode, the communication unit to enter a state where communication with the external equipment can be performed and the first guidance display unit to turn the light on.

An optical device such as a telescope may be connected to a camera through the use of a camera that acts as a lens cap for the optical system. The optical device may have an eyepiece and a housing within which a lens is retained. The adapter may have a cover portion, a housing attachment feature, an eyepiece attachment feature, and one or more camera attachment features. The cover portion may cover an end of the housing, and may have an imaging aperture. The housing attachment feature may be positioned at a periphery of the cover portion, and may attach the cover portion to the housing. The eyepiece attachment feature may be positioned proximate the imaging aperture to attach the cover portion to the eyepiece. The camera attachment features may facilitate attachment of a camera to the cover portion in alignment with the imaging aperture.

An image forming apparatus forms an image by optical scanning. The image forming apparatus includes: a light source; an image processing unit that processes image data; a modulation signal generation unit that generates a light source modulation signal; a light source drive unit that drives the light source based on the light source modulation signal; and a correction value identifying unit that identifies a correction value for correcting a registration error of an image to be formed. The image processing unit performs first image processing of image data with first resolution based on a correction value identified by the correction value identifying unit, the first image processing including deformation processing and gradation processing of the image data. The modulation signal generation unit converts image data processed in the image processing unit into image data with resolution higher than the first resolution and performs second image processing.

An image reading device includes a transport section that transports a recording medium along a transport path, an image reading section that is provided on one side of the transport path and reads an image formed on the recording medium transported through the transport path, a rotary body that is rotatably provided and is provided on a side opposite to an installation side of the image reading section across the transport path, and a protruding portion that is provided at least at one end portion out of one end portion and the other end portion of the rotary body in an axial direction and protrudes from the rotary body toward the image reading section side.

Disclosed is an image forming apparatus including: a colorimeter; a reader that reads an image formed on a recording medium; and a hardware processor that determines, in accordance with an operation state of the image forming apparatus or a type of a color measurement execution instruction, whether to execute color measurement by the colorimeter or to execute color measurement using the reader.
