In the method for improving the drawing in colour image reproduction by partial electronic retouching, the trichromatic sampling of a colour component of the colour image provides the trichromatic components which are subjected to an analog/digital conversion and stored in the memory (1). With a coordinate probe (50, 51, 52), a retoucher will proceed in the same way as with a retouching brush. By means of the probe, the coordinates of a moving area on the image (surface of the brush) of a trichromatic component to be retouched as well as the number of correction steps by image point will be searched. For the marked correction area the corrections will be calculated point by point. The trichromatic components of the coloured image or of a coloured printing will be read in the memory (1) and modified to obtain the retouching effect under the control of a monitor (2). The individual values of the corrections for each correction step may be freely selected. By previously determining the modifications ...

IMAGE EXTRACTION MASK

Image processing to remove red-eye features

A method of processing a digital image to detect and remove red-eye features includes identifying highlight regions (2) of the image having pixels with higher saturation and/or lightness values than pixels in the regions therearound, associating red-eye features (3) with at least some of the highlight regions, and performing red-eye reduction on at least some of said red-eye features. Further selection criteria may be applied to red-eye features before red-eye reduction is carried out. The invention identifies the highlight regions which may be associated with red-eye and then analyses regions surrounding the identified regions to determine whether they are associated with a red-eye feature. Highlight regions preferably have a sharp change in pixel saturation and/or lightness between the highlight region and adjacent regions.

System And Method For Applying A Reflectance Modifying Agent To Improve The Visual Attractiveness Of Human Skin

A computer-controlled system determines attributes of a frexel, an area of human skin, and applies a modifying agent (RMA) at the pixel level, typically to make the skin appear more youthful and so more attractive. The system scans the frexel, identifies unattractive attributes, and applies the RMA, typically with an inkjet printer. The identified attributes relate to reflectance and may refer to features such as irregular-looking light and dark spots, age-spots, scars, and bruises. Identified attributes may also relate to the surface topology of the skin, for more precisely enhancing surface irregularities such as bumps and wrinkles. Feature mapping may be used, for example to make cheeks appear pinker and cheekbones more prominent. The RMA can be applied in agreement with identified patterns, such as adding red to a red frexel, or in opposition, such as adding green or blue to a red frexel, according to idealized models of attractiveness.

An original image is read as an aggregate of a plurality of pixels in which adjacent pixels have different colors (R, G, and B) in a main scanning direction and in a sub-scanning direction, and the read pixels of the respective colors are stored in a line memory in association with information on relative positions of the pixels with respect to another pixel. Then, the stored pixels are sorted so that pixels having the same color are adjacent to each other, and an abnormal pixel (dust) not present in the original image is detected based on the state of the sorted pixels.
