When capturing images of a subject with an imaging device that uses a CMOS image sensor, a white band-shaped artifact appears in the imaging signal due to the influence of a rolling shutter operation performed when an external flash has been emitted. Manipulating or removing images in which such an artifact appears requires specifying the frames in which the artifact appears. A line averaging unit (11) calculates the average luminance level of each line in the imaging signal, the average luminance levels are temporarily stored by a storage unit (12), and thereafter a frame difference calculation unit (13) calculates the difference between the line average luminance levels and the line average luminance levels of the next frame. These frame difference values are compared with a reference value, and it is determined that the influence of an external flash is present if a portion of interest with high values is continuous for one frame period.

Provided are a method and apparatus for compensating for the degradation of a print image due to a malfunctioning nozzle that irregularly ejects ink. The method includes detecting a malfunctioning nozzle among nozzles installed in an inkjet image forming apparatus and increasing a dithering threshold of an adjacent position to a compensation position printed by the detected malfunctioning nozzle. The method adjusts a dithering threshold of a print position of the malfunctioning nozzle or a dithering threshold of an adjacent print position, and thus performs a halftoning transaction and prints an image. Accordingly, the degradation of print quality such as a visible white band can be prevented and the lifetime of the printhead can be lengthened.

A method of designing a roller bearing is disclosed upon clarifying mechanisms of damage patterns in respect of two kinds of brinelling, involved in the bearing, wherein white-banded flaking (brittle flaking) is a plastic instability phenomenon appearing under high-speed deformation accompanied by adiabatic shear deformation status with the resultant occurrence of adiabatic shear band (also called white band) inside material of the bearing. This enables all of the damage patterns to be determined upon making comparison between shear strain and shear strain rate, occurring inside the bearing, and discriminated values.

A pattern measurement method and a pattern measurement apparatus which use a scanning electron microscope are provided. SEM images of a measurement target pattern are respectively acquired at least two predetermined acceleration voltages. White band widths of the measurement target pattern are detected from the acquired SEM images.
