A monitoring system that monitors periphery of a shovel moving on ground and reports a tumble risk of the periphery of the shovel to an operator includes: a risk determination unit configured to determine a tumble risk in a case of movement of the shovel to the periphery based on distance information measured by a first sensor that is mounted on the shovel and measures a distance to a ground object including the ground in the periphery of the shovel and slope information measured by a second sensor measuring a slope of the shovel; and a display video generation unit configured to generate and output an image indicating the tumble risk determined by the risk determination unit.

Monitoring system monitoring periphery of mobile object, method of controlling monitoring system, and storage medium

The present invention relates to an image transfer system that transmits an image generated by an information processing apparatus to an image displaying apparatus. Upon detecting an instruction for starting the display of information relating to a network group that is formed via a network and includes the image displaying apparatus, the information processing apparatus that is connected to the image displaying apparatus via the network transmits an instruction for causing a group information image including information relating to the network group to be displayed to the image displaying apparatus via the network.

Information processing apparatus for transmitting an image to a display apparatus and method of controlling the same

An image signal in which a predetermined calibration pattern is synthesized in an input image is output. Based on the output image signal, transmittance or reflectance of a liquid crystal panel is controlled, and an image is formed. The image is projected by irradiating the liquid crystal panel with light, and the projected image is captured. A calibration pattern is extracted from the captured image. A correction parameter is generated depending on a condition of the extracted calibration pattern. Image capturing timing is controlled so that an image before or after update of transmittance or reflectance of the liquid crystal panel is not mixed in the image captured by an image capturing sensor based on timing at which the transmittance or the reflectance of the liquid crystal panel is updated by a liquid crystal control unit.

Projection apparatus, method for controlling the same, and projection system

An image projection apparatus comprises a projection unit configured to project an image onto a projection plane, a correction unit configured to correct a range of the image projected by the projection unit, a deformation unit configured to deform the projected range of the image according to a designated correction point, and a control unit configured to optically change the projected range of the image projected by the projection unit according to a designation of an outside of a predetermined range as the correction point.

Image projection apparatus and control method thereof

A projection apparatus includes a communication unit, an obtaining unit, a projection unit, a generator, and a controller. The communication unit communicates with an other projection apparatus. The obtaining unit obtains image data and the projection unit projects an image based on the image data obtained by the obtaining unit. The generator generates an on-screen-display (OSD) image. The controller controls the projection unit to project a projection image by superimposing the OSD image onto an image, based on the image data obtained by the obtaining unit, in a stack projection mode in which a projection image of the projection unit and a projection image of the other projection apparatus are projected to be superimposed with each other, and to transmit, to the other projection apparatus, information concerning a position at which the OSD image is superimposed.

Projection system

A projection apparatus for projecting an input image onto the projection surface includes a correction unit configured to correct distortion of an image to be displayed on the projection surface, a projection unit configured to project an image corrected by the correction unit, a communication unit configured to communicate with an external imaging apparatus, and a control unit configured to control the correction unit, wherein the control unit transmits distortion information concerning distortion of an image to be displayed on the projection surface to the imaging apparatus via the communication unit.

Display system

A projection apparatus which projects an image onto a projection plane based on an input image signal, the apparatus comprises: a division unit configured to divide an image represented by the input image signal into a plurality of regions; a deformation unit configured to deform various types of shapes of the images divided by the division unit; a combination unit configured to combine the images deformed by the deformation unit; and a projection unit configured to project the image combined by the combination unit onto the projection plane.
