摘要:
An authentication apparatus and authentication method which can improve the authentication accuracy are provided. The authentication apparatus consecutively picks up a biological authentication object of a predetermined biological part from different directions in series, and maps a plurality of images which are obtained as the consecutive image pickup result in series to a body of a figuration corresponding to the biological part with a point on the biological authentication object in the images being the criteria, and registers the respective images mapped to the body in a storage medium as information for collation with an image to be collated which is obtained by picking up an image from an arbitrary direction.

An image processing apparatus enables a user to widely select a desired transfer method, in relation to methods of transferring image data to be output to a transfer destination. To accomplish this, the image processing apparatus allows the user to set instruction information for instructing a transfer method of image data, and decides on a transfer method based on the set instruction information if the image data is color data. This transfer method includes a first transfer method of transferring color image data, a second transfer method of converting color image data to monochrome image data and transferring the monochrome image data, and a third transfer method of storing color image data in a storage unit and transmitting a report showing that image data has been received to a transfer destination printer.

An image processing apparatus performs a first edge determination to determine whether each pixel is an edge of a black character or a thin black line based on a pixel signal of a predetermined color in each pixel included in multi-valued image data. The image processing apparatus determines whether to achromatize a pixel signal of each pixel included in the multi-valued image data based on a result of the first edge determination, and achromatizes a pixel determined to be achromatized. The image processing apparatus performs a second edge determination for determining whether each pixel is an edge based on a pixel signal of a color different from the predetermined color in each pixel included in the multi-valued image data. The image processing apparatus corrects the multi-valued image data based on a result of the second edge determination after completing achromatization of the pixel determined to be achromatized.
