  • Patent number: 6765692
    Abstract: An image can be outputted with a high sharpness without deteriorating a resolution. In order to output an image of a high picture quality while suppressing the occurrence of a moire, an exposure amount is modulated in accordance with pixel density information of the image divided into pixels of a predetermined size by an exposure amount modulating unit in a light scanning unit, thereby expressing an image dark/light state. In this case, in a highlight density region in which a pixel density is equal to or less than ⅓ of the maximum image density, the density data of two adjoining pixels is modulated by one pixel and the other pixel is not recorded. In a density region in which the image density lies within a range from ⅓ to ½ of the maximum image density, a part of the density data of one of the two adjoining pixels is transposed to the other pixel.

  • Publication number: 20030135387
    Abstract: A transmitter-receiver 11 accepts delinquency information indicating a delinquent situation of a repairing reserve to be paid by a comparted owner of an apartment house from a financial institution terminal 3. On the basis of the delinquency information, a delinquency rate forecasting unit 21 forecasts an average delinquency rate and its standard deviation. A marginal stress searching unit 20 calculates a cumulative reserve and calculates a marginal stress under a constraint that a cumulative reserve is not below an expenditure. A less marginal probability calculating unit 21 calculates a probability of the marginal stress or less. A permissible risk checking unit 18 checks whether or not its probability is within a tolerance range, and a revised amount calculating unit 17 revises a repairing reserve amount if the probability is beyond the tolerance range.

  • Patent number: 6538683
    Abstract: An object of the present invention is to solve a problem in which in an image forming apparatus which performs pulse width modulation, when the maximum pulse width is changed to change the maximum density, the exposure amount in patch formation also changes to make it difficult to accurately control the patch and maintain gradation characteristics. To achieve this object, the maximum pulse width of pulse width modulation can be changed. It is determined whether a patch is to be formed. For normal image formation, the maximum pulse width is set to a changed value. For patch formation, the maximum pulse width is set at a predetermined value, and an image is formed.

  • Patent number: 6535302
    Abstract: When pixels in a two-dimensional matrix are divided into lines A and B in the column (or row) direction (sub-scanning direction) and two neighboring pixels in the row (or column) direction are subjected to gradation correction respectively using characteristic curves for lines A and B, the characteristic curve for line B unpreferably has a stepwise characteristic portion having a step when it is stored in an LUT, due to quantization errors unique to digital values. Hence, the characteristic curve for line A is set to be decreased by the amount corresponding to the step.
