摘要： An imaging device includes a color filter having a predetermined color array and converts an optical image into image data of an electrical signal. A coordinate transforming unit transforms a first coordinate value of the imaging device into a second coordinate value in a state of the color array according to a color of the color filter corresponding to the first coordinate value. The imaging device reads out a pixel value of a pixel at the second coordinate value as a pixel value of a pixel at the first coordinate value by setting the first coordinate value as a coordinate transform destination and the second coordinate value as a coordinate transform source.

摘要： An image projecting apparatus enables the formation of a projected image faithful to original image information by reducing degradation in the projected image due to decrease in imaging performance of a projection optical system. Image information is processed by an image processing device, which includes a first and a second image processor. A light modulating device modulates a flux of light emitted by an illumination optical system based on the processed image information. The modulated flux of light is projected on a screen by a projection optical system. If the image information processed by the first image processor in a pixel region is not within a representable modulation range of the light modulating device, the image information is processed by the second image processor.
