摘要： In image processing according to the prior art, the important part of photographic image data (referred to herein as the object) could not be determined and therefore required human participation. A computer 21 which is the core of image processing calculates an edginess which is an image variation from a differential value of data for adjacent picture elements in a step SA110, and determines object picture elements by selecting only images with a large variation in steps SA120, SA130. As optimum parameters for contrast correction and lightness compensation are calculated from image data for object picture elements in steps SA310-SA330, image processing indicators based on object picture elements are determined, and optimum image processing can be performed automatically. After summing a luminance distribution for each area of the image, which is a feature amount, while uniformly selecting picture elements in a step SB110, a reevaluation is performed by a weighting determined for each area in a step SB120, and a luminance distribution strongly influenced by the luminance distribution of the photographed object is thus obtained with uniform sampling. After determining the intensity of this luminance distribution insteps SB130-SB150, the image data is converted in a step SB160, and image processing can therefore be performed with optimum intensity while reducing the processing amount.

摘要： In a color correction apparatus for correcting the color image data, a color adjustment amount for canceling a difference between the optimum value (Rt, Gt, Bt) predetermined for the fixed-color pixel and the result of the summing-up is obtained. Therefore, the color adjustment amount is corrected on the basis of the fixed elemental color elements of the pixel, and the color image data is color-corrected on the basis of the corrected color adjustment amount. Since a computing equation for adjustment operation is simple, the processing time can be shortened. Further, since the color adjustment amount is corrected on the basis of the fixed memory color element of each pixel, it is possible to suppress color jumping.

摘要： Traditionally, the operator must determine the type of an image displayed on a screen and manually select one of various kinds of effect processing for the type of the image. As is generally known, however, such operations have a lack of accuracy and are difficult for an untrained user to carry out. In addition, the image is not correctly compensated for color slippages over the entire gradation range. Furthermore, in the case of image data including an abnormal element other than just a color slippage, the image can not be corrected with a high degree of efficiency. At a step S102, a sample-count distribution of image data is found for each color component by applying a thinning technique on samples. At a step S116, a judgment as to whether or not analogy exists among the sample-count distributions of the color components is formed. A low degree of analogy is regarded as an indicator which suggests that characteristics recognized from the sample-count distributions shall naturally be made uniform among the color components. In this case, the characteristics are compensated for a color slippage included therein by correcting an offset, putting an emphasis on the contrast and correcting the brightness at steps S204 to S216 in order to produce a well pitched and good image from the image data with poor color reproducibility. In addition, since the compensation and correction work is automated, even an untrained user is capable of correcting the balance of color with ease. Furthermore, at a step S205, an offset quantity reflecting a degree of analogy is calculated for use in the compensation of the characteristics for a color slippage.

摘要： When a memory card is inserted into a slot, the control circuit of a color printer obtains image output control information from a memory card and analyzes it. When auto light source is not set as the light source, the CPU references the reference values and coefficients for the characteristics parameters except for color balance and performs correction, and then adjusts the image data image quality to reflect the post-correction characteristics parameters. As a result, it is possible to automatically adjust the image quality of image data without losing the selectively set output conditions.

摘要： A CPU divides an image into plural regions and for each of the regions, generates a histogram and calculates an average brightness Y ave. The CPU determines a focus location on the image by using focus location information, sets a region at the determined location as an emphasis region, and sets the average brightness Y ave of the emphasis region as a brightness criterion Y std. The CPU uses the brightness criterion Y std to determine non-usable regions. By using the regions not excluded as non-usable regions, the CPU calculates an image quality adjustment average brightness Y′ ave, i.e. the average brightness of the entire image, with a weighting W in accordance with the locations of the regions reflected thereto, and executes a bright value correction by using the calculated image quality adjustment average brightness Y′ ave.

摘要： Image processing apparatus 10 analyzes image data to acquire picture quality characteristic values, and uses shooting information SI and image processing control information GI associated with the image data to define a scene correction condition and an arbitrary correction condition. The image processing apparatus 10 preferentially uses information from the image processing control information GI, while using [information] from the shooting information SI where this information is not present in the image processing control information GI, with the aim of effective mutual utilization of image processing control information GI and shooting information SI. The image processing apparatus 10 defines an automatic correction level AP on the basis of the acquired picture quality characteristic values, scene correction condition and arbitrary correction condition, and defines a manual correction level MP on the basis of a manual correction condition in the image processing control information GI. Utilizing the automatic correction level AP and manual correction level MP, the image processing apparatus 10 executes a picture quality adjustment process to correct the image data.

摘要： In case where photo information PI (Exif IFD) is included in image data GF, a CPU calculates a modified contrast correction amount tCurve_cont and a modified brightness value correction amount tCurve_Y, in consideration of an exposure correction amount (a light exposure) EV. The CPU applies the obtained modified contrast correction amount tCurve_cont and the modified brightness value correction amount tCurve_Y to a tone curve, and executes an adjustment of image quality including contrast and brightness value. In other words, the CPU modifies characteristics of the tone curve by using the modified contrast correction amount tCurve_cont and the modified brightness value correction amount tCurve_Y, and adjusts the image quality of the image data by applying the modified tone curve to the image data GD.

摘要： Electronic data output from CCD is separated into a brightness component Y and color difference components Cb and Cr and an edge is extracted for each of the components. The edge amounts are calculated from the extracted edges and the component having the maximum edge amount is selected. Edge information (for example, edge gradient direction) is calculated based on the selected component having the maximum edge amount, a filter is selected based on the calculated edge information about the component having the maximum edge amount, and smoothing processing is performed for the electronic data output from the CCD based on the filter. The electronic data subjected to the smoothing processing is written into flash memory.
