Abstract
An image detecting apparatus is used to detect an image of a pattern of lines on a palm. The image detecting apparatus has an optical transparent block which has a refractive index greater than that of a surrounding medium. The optical transparent block also has a convex curved surface on which the palm is placed. The image detecting apparatus further includes a light source for emitting light towards the convex curved surface through the optical transparent block, and an image sensor is provided for detecting at least the light reflected from the convex curved surface.
