    Abstract: A representative-value calculator calculates a representative value of signal values of pixels included in each of divided regions of a neighboring region of a pixel of interest. The divided regions are obtained by dividing the neighboring region into the predetermined number of divisions. The number of divisions is determined based on a frequency band in an input image signal. A difference-absolute-value calculator calculates a difference absolute value between a signal value of the pixel of interest and each of the representative values of the respective divided regions. A weight calculator calculates a weight for each of the representative values of the respective divided regions according to the difference absolute value. A normalization processor normalizes the sum of products of the representative values of the respective divided regions and the weights for the representative values of the respective divided region.

    Abstract: An image processing device includes an image correction unit which receives a synthesized image and pseudo color pixel information indicating a pseudo color pixel position included in the synthesized image and executes pixel value correction. The image correction unit selects non-pseudo color pixels as reference pixels from a reference region set in a surrounding region of the pixel to be corrected, sets a similarity weight coefficient in which a large weight is set as a pixel value of the reference pixel that is close to a pixel value of the pixel to be corrected and a pixel position weight coefficient in which a large weight is set as the pixel value of the reference pixel that is near a pixel position of the pixel to be corrected, with respect to the reference pixels, and determines a correction pixel value of the pixel to be corrected by a weighted summation process.

    Abstract: A workpiece conveying apparatus for conveying a workpiece disposed in a through hole in a conveying table allows the workpiece to be reliably dismounted from the through hole using compressed gas, suppresses the workpiece from unintentionally jumping out because of residual pressure of the compressed air, and increases the conveying efficiency. In an electronic-component conveying apparatus, a conveying table is arranged to face a conveying surface of a conveying stage, with an electronic component disposed in a through hole in the conveying table. When the conveying table is rotated, the electronic component is conveyed. The conveying surface has an exhaust hole at a position where the electronic component is to be dismounted. The total area of the opening of the exhaust hole in the conveying table is larger than the area of the surface of the electronic component facing the conveying surface of the conveying stage.
