Abstract: An image distribution apparatus obtains a plurality of images generated by a plurality of image capture apparatuses capturing images of a predetermined subject from different directions, transmits the plurality of images to the plurality of display apparatuses, receives, from the plurality of display apparatuses, viewed image information regarding an image being displayed/reproduced in the plurality of display apparatuses, calculates a degree of attention for each of the image capture apparatuses capturing the images, based on the viewed image information, and transmits, to each of the image capture apparatuses, notification control information for causing a notification unit of the image capture apparatus, the notification unit being disposed in the same orientation as a lens unit of the image capture apparatus, to give notification based on the degree of attention.

Abstract: An image projection apparatus configured to project an image on the projection surface includes a light modulation unit configured to modulate light from a light source unit, an image processing unit configured to generate an image signal to be input to the light modulation unit, disposed in the image projection apparatus and, a light intensity measuring unit configured to measure an intensity of part of the modulated by the light modulation unit, a light guide optical system configured to guide the part of the light to the light intensity measuring unit and another part of the light to the projection surface, and a correction unit configured to correct brightness of the image projected on the projection surface based on a video signal supplied to the image projection apparatus and a measurement result of the light intensity measuring unit.
