摘要： A white balance coefficient setting unit 51 sets a white balance coefficient for an image signal; a white balance correction coefficient determination unit 52 determines two white balance correction coefficients to be applied to a luminance signal of the image signal in accordance with the white balance coefficient; a luminance signal operation unit 59 obtains two output signals by multiplying the luminance signal by each of the two white balance correction coefficients; a first adder 57 adds one of the two output signals and a first color difference signal of the image signal together; a second adder 58 adds the other output signal and a second color difference signal of the image signal together. Adding results of the first and the second adders 58 and 59 will be output as a white balance correction value to be applied to the two color difference signals.

摘要： 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.

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： 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.
