    摘要： A natural white balance is achieved in images that are captured while emitting a flash. A WB adjustment portion is provided with a mixture ratio calculation portion that estimates a mixture ratio of an external light component and a flashed light component that are present in an image that is captured with emitting a flash, from the image obtained that is captured while emitting a flash and an image signal that is obtained without emitting a flash, an external light WB coefficient determination portion that determines an WB coefficient for the external light, a flashed light WB coefficient setting portion that sets a WB coefficient for the flashed light, and a WB processing portion that continuously performs WB processing on the image captured while emitting a flash by using the mixture ratio as an interpolation ratio.

    摘要： 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.

    摘要： The gradation correction device includes a luminance signal convertor to generate a luminance signal from the input R, G, B signals, a correction coefficient calculator which calculates the ratio to the luminance signal of the luminance signal after gamma correction to the predetermined gradation characteristics, and a multipliers to multiply the output from the correction coefficient calculator by each of the R, G, and B input signals. When the gradation correction is applied, effective brightness adjustment can be applied with no change in hue and saturation and without exceeding the dynamic range of a device.

    摘要： In the disclosed thermal gradation printing apparatus, heat elements in a line-type thermal head are divided into a plurality of groups, and an accumulated heat amount in the substrate of the thermal head for each group is estimated based on the pulse width data applied to each heat element considering the influences by heat accumulations in the main-scanning direction and in the sub-scanning direction. Based on the group division estimated accumulated heat amounts and the temperature of the body portion of the thermal head, a correction value for the pulse width data to be applied to each heat element. Moreover, the correction value is applied to the pulse width data for each heat element, so as to output the corrected pulse width data to the thermal head.
