摘要： PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus for carrying out field reading by using a CCD provided with color filters adopting the color difference line sequential system, displaying a whole image on the basis of signals of odd number fields and signals of even number fields, and suppressing production of a stripe pattern when the levels of luminance signals differ between the odd number fields and the even number fields.
SOLUTION: The electronic endoscope apparatus extracts part components of a luminance signal by applying blur processing to a luminance signal of odd number fields O1 to generate a blur processed luminance signal, adds the blur processed luminance signal to a luminance signal of even number fields E1, produces a whole image signal by using color difference signals and the luminance signal of the even number fields resulting from summating the luminance signal of the odd number fields O1, the color difference signals, and the blur processed luminance signal, and displays a whole image of a subject on the basis of the whole image signal.

摘要： PROBLEM TO BE SOLVED: To perform fine hue adjustment matched with the purpose of an examination to images acquired by an electronic endoscope. SOLUTION: The hue of the image is adjusted by replacing the value of the color of each pixel which forms the image by using a replacement table (LUT) (S502). In the replacement table, the correspondence of the colors is defined so that a hue in a range of the color which is necessary for diagnosis is wider than a hue in a range of the color which is not necessary for diagnosis. The replacement table is prepared for each purpose of the examination and is used properly. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To output a highly diagnostic image at a monitor by adjusting sharpness by an endoscope image apparatus. SOLUTION: A luminance distribution image representing the luminance distribution of an image is produced. The luminance distribution image is produced by generating a luminance image composed of the luminance components of the image and then blurring it for instance (S401-403). Then, an enhancement amount of sharpness is determined for each pixel based on the value of each pixel of the luminance distribution image (S404). Further, the enhancement amount for each color is determined based on the determined enhancement amount of the sharpness (S405), and a brightness adjustment value and a saturation adjustment value corresponding to the portion are added to the pixel value of the original image (S406).
