摘要： 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.

摘要： An image pickup apparatus generates a display image signal by implementing predetermined dynamic range expansion processing on an image signal obtained by performing underexposed image pickup, and detects an image region in which a pixel within a predetermined gradation range exists as a warning region from the image signal either prior to implementation of the predetermined dynamic range expansion processing or following implementation of the predetermined dynamic range expansion processing. The image pickup apparatus synthesizes the display image signal with a warning pattern corresponding to the warning region and displays the synthesized image as a live view image.

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.
