摘要： A color image forming method and an apparatus to be used for executing the method are provided which are capable of effecting more faithful color reproduction with respect to a target color, and also, a color correction factor determining method to be used in the above method and apparatus. The color image forming apparatus to which the color image forming method is applied is arranged to subject three primary color luminance signals (R, G, B) to linear matrix calculation by a luminance matrix device for conversion into second luminance signals (R', G', B') to correct deviation of wavelength of the spectral absorbing characteristic of the ink, and to subject each color of the second luminance signals (R', G', B') to complementary color conversion into three primary color density signals (D.sub.R, D.sub.G, D.sub.B) by a complementary color converting device, and further, to subject the three primary color density signals (D.sub.R, D.sub.G, D.sub.B) to color correcting calculation by a color correcting device for conversion into ink density signals (C, M, Y), so as to correct color turbidity due to the unnecessary component of the ink. Additionally, the correction factor determining method determines the luminance matrix factor used for the luminance matrix calculation and the color correction factor used for the color correcting calculation by minimizing conditions of a color difference to be perceived by man.

摘要： In an image processing method for correcting a target pixel using emphasizing and smoothing components, a microcomputer stores the input image signal into an image memory, and generates the enhancement coefficient k data in the enhancement coefficient table memory using a function with an input/output characteristic whereby the output is a simple increasing value when the input is approximately zero. Using a first difference, which is the difference of the target pixel signal minus the signal of the reference pixel positioned on a first direction, the enhancement coefficient k is obtained by referencing the enhancement coefficient table, and the target pixel is enhanced proportionally to the enhancement coefficient k and the first difference. The target pixel is also gradated or smoothed in proportion to the enhancement coefficient k and the second difference, which is the target pixel signal minus the average of the signals of the second and third reference pixels, which are the reference pixels in the directions perpendicular to the first direction and on opposite sides of the target pixel. The target pixel signal is corrected by repeating this process for each of the reference pixels positioned on the four directions surrounding the target pixel, and the corrected image signal is stored to the image memory. The enhanced image signal is obtained by repeating this process for all input image signals.

摘要： In the three-dimensional imaging device (three-dimensional image processing device), the depth acquisition unit acquires L depth information and R depth information from a three-dimensional image. The image correction unit adjusts disparities of edge portion areas of a subject based on the L depth information and the R depth information such that the normal positions of the edge portion areas of the subject are farther away. Accordingly, when a three-dimensional image acquired by the three-dimensional imaging device is three-dimensionally displayed, the edge areas of the subject are displayed having a sense of roundness. As a result, a three-dimensional image that has been subjected to processing by this three-dimensional image processing device is a high-quality three-dimensional image that can appropriately reproduce the three-dimensional appearance and sense of thickness of the subject and has little of the cardboard effect.
