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.

An interpolation apparatus for preventing image deterioration caused by correlation detection errors. The apparatus comprises a calculation means for obtaining the arithmetic mean of pixels on the scan lines above and below the line being interpolated, a correlation value detection means for obtaining the correlation value of the pixels, a setting means for outputting the reference value of correlation, a comparison means for outputting a binary signal set, a determination means for determining the interpolation line, and a selection means for selecting and passing the output of the calculation means.

Interpolation method and apparatus for interpolating pixels using levels of pixels surrounding a pixel to be interpolated is disclosed whereina level difference between two pixels on an interpolation line is calculated for all interpolation lines, likelihoods of correlation are calculated from the level differences obtained using a membership function,an interpolation direction is determined based on the likelihoods of correlation and directions of the interpolation lines and an interpolation value for the pixel to be interpolated is calculated based on levels of two pixels on the interpolation line having the interpolation direction determined.

An apparatus for printing video images is disclosed. First the percentage of backlighting or people in the image is detected. That is, the probability of the presence of backlighting or people is detected. Then, the density gradation table is modified based on the detection result, and the presence of backlighting or the presence of people in the image is evaluated based on optical information, to select the best density gradation table from among plural density gradation tables, or to synthesize the best density gradation table. A luminance table is generated using the optimized density gradation table, and gradation correction of the image is then accomplished using that luminance table.

When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. If multi-screen print is carried out on a printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

In order to avoid a load change which occurs when seam O passes by the heads affect image information, a dyeing layer transfer head and recording heads are located in equal intervals having length P, which is obtained by equally dividing an entire circumference K of a recording intermediate belt by n (n is integer), and, given that the position of the seam of the recording Intermediate belt, which does not have an end obtained by coupling two ends of a belt body of a band shape, is origin O, images are formed in portions except for portions at origin O, or at a distance of 1×P, 2×P, . . . (n−1)×P from origin O. In this way, it is possible to prevent deterioration in the image quality, such as a stripe line in an image formed by an image forming apparatus.

In interpolation lines having plural angles passing through an attentional pixel on a scanning line in one field to be interpolated having pixels on an upper scanning line placed over the attentional pixel and pixels on a lower scanning line placed under the attentional pixel, a horizontal spatial frequency is detected in the vicinity of the attentional pixel to be interpolated, interpolation directions are derived by plural interpolation direction decision steps on the basis of obtained spatial frequency information, and the scanning line is interpolated by selecting one direction of the plural interpolation directions.

In an image data including tone information, a level of an attentional picture element in an image and a level of an adjacent picture element located adjacent to the attentional picture element are smoothed to create a first substitution level, and by internally dividing the level of the attentional picture element and the first substitution level with a predetermined internal division ratio to obtain a second substitution level which finally substitutes the level of the attentional picture element.
