A method for automatic keystone correction in a projection system is provided that includes rectifying a first image to be projected using current keystone correction parameters to generate a first rectified image, projecting, by a projector in the projection system, the first rectified image on a projection surface, determining whether or not current keystone correction parameters are providing sufficient keystone correction after the first rectified image is projected, rectifying a second image to be projected using the current keystone correction parameters to generate a second rectified image if the current keystone correction parameters are providing sufficient keystone correction, computing new keystone correction parameters if the current keystone correction parameters are not providing sufficient keystone correction and rectifying the second image to be projected using the new keystone correction parameters to generate the second rectified image, and projecting, by the projector, the second rectified image on the projection surface.

A lighting apparatus with an image-projecting function that is convenient for a user is provided. It includes: an illuminating unit that emits illumination light; a projection-type image display unit that emits image-projecting emission light for projecting an image; and a sensor that emits operation-detecting light for operation detection and that is capable of detecting an operation by an operation object in a range including an image projection area of the projection-type image display unit, and is configured so that the image-projecting light, and the operation-detecting emission light have respective different wavelength distribution characteristics, and regarding a light amount in the wavelength range of light used by the sensor for the operation detection, a light amount of the operation-detecting light is the largest among those of the illumination light, the image-projecting emission light, and the operation-detecting light.

Certain configurations are described herein of a fluid handling apparatus that comprises a projector configured to provide an image of labware onto a support. The provided image can be used to assist a user in proper placement of the labware onto the support. The system can be configured to determine if the labware has been properly placed prior to beginning any fluid handling operations.

A projection control device includes: a communication unit connected to communicate with an image capturing device configured to capture an image of a target object positioned around a projected object; a derivation unit configured to derive a projection position of a content image based on designation of a parameter related to the content image to be projected onto the projected object and an image of the projected object including the target object; a projection image generation unit configured to generate a projection image including the content image disposed at the derived projection position; and a control unit configured to transmit a projection instruction of the projection image to a projection device via the communication unit.

A projection image automatic correction method and system based on binocular vision. The method includes: acquiring a depth map of a projection image on a projection plane; calculating a first transformation relationship between a source image and the projection image; acquiring a distortion image according to the depth map; acquiring a correction image after correcting the distortion image; calculating a second transformation relationship between the distortion image and the correction image; acquiring a correction relationship between the source image and the correction image according to the first transformation relationship and the second transformation relationship; and correcting the projection image according to the correction relationship. This disclosure is configured to realize the efficient automatic correction of the projection image without being limited by the projection area, and the correction flexibility is high.

To provide a display control system in which a terminal device and a display device operate in tandem. The display control system comprises a terminal device 10 having an image-capture unit, a display device 50 for displaying video, and a control device 20 for controlling the display device 50. The terminal device 10 or the control device 20 identifies a capture range in video displayed by the display device 50 on the basis of an image captured by the image-capture unit. The control device 50 controls the display state of the video displayed by the display device 50 on the basis of the identified capture range. This configuration allows for interactive special effects such as making an object in the capture range of the terminal device 10 disappear from the video or making objects in the capture range of the terminal device 10 appear in the video.

Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.

A projection display device and a projection display equipment are provided. The projection display device includes a display screen body, a photosensitive device, and a control module. The control module is electrically connected to the display screen body, the photosensitive device outputs a photosensitive signal when sensing a projection light beam, and the control module is electrically connected to the photosensitive device to receive the photosensitive signal and to control a section on the display screen body corresponding to a projection position of the projection light beam to be converted from a transparent state to an opaque state according to the photosensitive signal.

An image projection device includes: a calculation processor which executes a video mute operation on the basis of a video mute manipulation signal for requesting the video mute operation, determines whether or not a screensaver of video output equipment has been activated on the basis of a first signal input from the video output equipment, determines the presence or absence of a second signal to be input from the video output equipment, and determines whether or not information indicating the activation of the screensaver of the video output equipment has been stored. The calculation processor determines to continue the video mute operation when the video mute operation has been requested, when it is determined that there is no second signal, and when it is determined that the information indicating the activation of the screensaver of the video output equipment has been stored.

Content data representing content that includes at least one or more components is acquired. Projection area data representing a projection area is acquired. A deteriorated part, which is a part where a projection condition is deteriorated in the projection area, is identified based on the projection area data. A priority of the component included in the content is identified. Display deterioration of the content, which is caused by the deteriorated part, is suppressed based on a position of the identified deteriorated part in the projection area, the content data displayed on the projection area, a threshold according to the identified priority, and a degree of deterioration indicative of a level of deterioration of the component.
