摘要:
A geometrical correcting method allowing geometrical correction to be performed simply, accurately and in short a time, even in a multi-projection system including a screen of complex shape and projectors complexly arranged, for significantly improving the maintenance efficiency. Test pattern images having feature points are projected by respective projectors, and captured and displayed on a monitor, approximate positions of the feature points are designated and input while referring to the displayed test pattern captured image, and the accurate positions of the feature points in the test pattern images are detected according to the approximate position information. An image correction data for aligning the images projected by the projectors is calculated from the detected positions based on the feature points, the coordinate information of the feature points in a predetermined test pattern image, and the coordinate position relationship between a separately predetermined contents image and the test pattern captured image.

The object of the present invention is to provide a multi-primary color display method and device, which can achieve miniaturization and perform multi-primary color display with high definition and finer gradation without decreasing the time resolution. When displaying an image by four or more primary colors, a first image is formed by light of two or more primary colors, and the image consisting of four or more primary colors is displayed by spatially modulating the first image with a second image consisting of two or more primary colors having spectroscopic characteristics different from spectroscopic characteristics of the light of primary colors forming the first image.

A correction data acquisition method for an image display device, which is used to display a predetermined image using a plurality of primary colors. An offset image at a black level is displayed at an image display section of the image display device. A multiband offset captured data is acquired by capturing the offset image through filters corresponding to primary colors. Primary color images at predetermined signal levels of the corresponding primary colors are displayed sequentially. A multiband primary color captured data is acquired by capturing the primary color images through the filters for the corresponding primary colors. Primary color scale images are displayed by varying input signal levels of the corresponding primary colors sequentially. Primary color scale captured data is acquired by capturing the primary color scale images sequentially. Calculation is made of the offset correction data on the multiband offset captured data, the multiband primary color captured data and the primary color scale captured data, so as to acquire correction data relating to color shading in the image display device.

An image capturing apparatus includes a first image sensor unit, a second image sensor unit, and a spatial frequency reduction unit. The first image sensor unit is capable of subjecting an object image formed by an imaging lens to a photoelectric conversion to output a first image signal having a first resolution and constituted by a first number of colors. The second image sensor unit is capable of subjecting the object image formed by the imaging lens to a photoelectric conversion to output a second image signal having a second resolution that is lower than the first resolution and constituted by a second number of colors that is larger than the first number of colors. The spatial frequency reduction unit reduces a spatial frequency of the object image formed on a light receiving surface of the second image sensor unit by the imaging lens.
