    • The present invention accurately reproduces an image pattern by referring to neighboring pixels upon determining the threshold value of a target pixel so that a delay in dot generation can be prevented while emphasizing an image transition portion so that both graininess and sharpness are improved in the image. To this end, a neighboring pixel density difference detection part obtains an absolute value of the density difference between a target pixel and its neighboring pixels and selects the density of a neighboring pixel with a large absolute value as a reference pixel density. Further, a threshold value quantity determination part determines a threshold value corresponding to the density selected by the neighboring pixel density difference detection part. Then, a quantization part outputs an output value based on a comparison between the threshold value and a corrected value obtained by adding a pre-calculated error value of neighboring pixels to an input value.
    • 本发明通过在确定目标像素的阈值时参照相邻像素精确地再现图像图案,使得可以在强调图像转换部分的同时,可以防止点生成中的延迟,使得图像中的颗粒度和锐度都提高。 为此,相邻像素密度差检测部分获得目标像素与其相邻像素之间的浓度差的绝对值,并且选择绝对值大的相邻像素的浓度作为参考像素密度。 此外,阈值量确定部确定与由相邻像素密度差检测部选择的浓度对应的阈值。 然后,量化部分基于阈值与通过将相邻像素的预先计算的误差值相加到输入值而获得的校正值之间的比较来输出输出值。

    • An information processing apparatus, which can expand a part of a function by the addition of software, enables the development of additional software that does not depend on the firmware version. The information processing apparatus has a startup routine that switches a startup task in accordance with a state of a specific input terminal of an input/output (I/O) port set in accordance with presence or absence of a problem in a flash ROM. An executable file in a memory incorporated in the information processing apparatus which has a specific name is loaded and executed at startup. After the file has been executed, an operation corresponding to an external event is started. The information processing apparatus may use a Next Fit memory allocation method to reduce memory fragmentation. A reduction in memory fragmentation may be performed before and after a photograph is taken in a camera using a flash memory, or before or after recording or erasing is performed. Also described are a program loader, binding of common data, copying and erasing of files, an abstract input/output port, hook management software, counting programs for power consumption control, a three-layer shutdown process, and detection and display of errors.

    • A direction being across the defective pixel and along which pixels used to calculate a signal level of a defective pixel are located, is determined. A ratio between signal levels of pixels that are adjacent to the defective pixel and that have a different color from the defective pixel, and signal levels of pixels that are adjacent to pixels being located along the determine direction with respect to the defective pixel and having the same color as the defective pixel and that have a different color from the defective pixel, is acquired. A value obtained by multiplying an average value of the signal levels of the pixels used to calculate the signal level of the defective pixel by the calculated ratio is output as the signal level of the defective pixel.
