Title: Method for scanning photographic film picture using selectively determined system responding gain calibration
Inventor: BRYANT STEVEN M
IPC: H04N1/19
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To improve system response characteristic during picture scanning by preparing the composite gain profile of each pixel from the selected combination of an open gate and a minimum density (Dmin) gain profile. SOLUTION: The gain value for each pixel with respect to prescribed line scanning can be obtained mainly from open gate scanning. By obtaining a composite gain profile from properly selected combination of the open gate and the Dmin gain profile, a more precise Dmin gain is used in a pixel area maximizing the difference between the open gate and the Dmin in order to optimally adjust the failure of a narrow illumination source. Then, an open gate gain is used everywhere in scanning in order to minimize the fear of local incompleteness such as dust and flaws at the Dmin part of a film where the Dmin gain can be obtained.

Title: Sheet material feeder and image forming device
Inventor: SATO AKIHIRO
IPC: B65H3/46
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To find the time to change a sheet material feeder means more accurately than before. SOLUTION: The rotation speed v1 of a paper feeder roller and the rotation speed v2 of a separation roller detected by encoders are compared (Step 1 to 3), a count index number is added to a count area when v1≈v2 (Step 4). When the speeds v1 and the speed v2 are different (Step 5), the count area is updated by adding a count index number multiplied by a speed coefficient reflecting the difference (Step 6, Step 7). A CPU checks whether a count value reaches a prescribed value when the value is updated (Step 8, Step 9). If the count value reaches the prescribed value, the CPU determines that the time limit for changing a pick up roller, a paper feeder roller and a separation roller is reached and indicates that effect (Step 10).
