    摘要: Provided are an information processing apparatus, an information processing method, and a storage medium capable of drawing a fine ridge line with high accuracy. The information processing apparatus includes: an information acquisition unit that acquires sweat gland pore information including position information about a sweat gland pore extracted from an image including a skin marking and directional information about the sweat gland pore for each of the sweat gland pores; and a ridge line drawing unit that draws a quasi ridge line based on the sweat gland pore information.

    摘要: A fingerprint capture system, a fingerprint capture device, an image processing apparatus, a fingerprint capture method, and a storage medium that can acquire a high quality fingerprint image are provided. A disclosed example includes: a capture unit that captures a fingerprint; an image processing unit that processes a transferred fingerprint image captured by the capture unit; a display unit on which the fingerprint image transferred to the image processing unit is displayed; a recording unit where the fingerprint image transferred to the image processing unit is recorded by the image processing unit; and an instruction unit that inputs, in the image processing unit, a record instruction that instructs the image processing unit to record the fingerprint image in the recording unit. The image processing unit records, in the recording unit, the fingerprint image displayed on the display unit at the time the record instruction is input by the instruction unit.

    摘要: Provided are a fingerprint reading device and a fingerprint reading method that can appropriately read a fingerprint even when reading a fingerprint of a relatively soft finger that may be easily subjected to significant elastic deformation. The fingerprint reading device includes: a placement portion on which a finger is placed, provided with a reading face so as to be able to move between first and second positions; a drive unit that causes the reading face to move between the first and second positions; and a reading unit that reads a fingerprint when the reading face is positioned at the first position, the drive unit causes the reading face to move to the second position and further move from the second position to the first position, and the reading unit reads a fingerprint when the reading face has moved from the second position to the first position.
