Abstract: PURPOSE:To miniaturize a picture reader and to attain sure shading correction by using a white plate to correct the variance of reading sensitivity when a sensor is set at an initial position, and a light shielding plate to cut off the external light to a light source. CONSTITUTION:A white plate, i.e., a shading correction plate 1 is set opposite to a line sensor 6 which is set at its initial position and corrects the variance of the reading sensitivity, i.e., the shading. Thus, it is just required that an end part 1p of the plate 1 is set at a position where a focus range   which covers least and necessarily the focus position O of a multi-lens array 5, for example, therefore, the length of the plate 1 can be reduced.

Title: Probability integration system
Inventor: NINOMIYA SHOICHI
IPC: G06F19/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of the memory while maintaining necessary calculation accuracy and also to perform fast probability integration by inhibiting production of an endpoint node when the attainment probability of a node is smaller than a prescribed constant. SOLUTION: Probability integration in the process of probability which uses a n-ary tree to be reconnected is performed. A block 510 stores a constant C in a storage device of a system. A block 520 produces a node and calculates the attainment probability of the node with the system. When the node is an endpoint node and also the attainment probability is smaller than the constant C, a block 530 inhibits node production. When the inhibited endpoint node is an upper end node, the block 530 adds the attainment probability of the inhibited endpoint node to the attainment probability of a node that is lower by one than the inhibited endpoint node. When the inhibited endpoint node is a lower end node, it adds the attainment probability of the inhibited endpoint node to a node that is upper by one than the inhibited endpoint node.
