Inventor: HORIGUCHI MASASHI
IPC: G03D15/00
Filed: 1985-10-18
Abstract: PURPOSE:To immediately print a picture after the front or rear face of a film is discriminated, by measuring an infrared absorption spectrum to discriminate the front or rear face of the photographic film. CONSTITUTION:The infrared absorption spectrum is different between total reflection of infrared rays on the boundary face between a prism 16 and a base layer and that between the prism 16 and a gelatin layer. This difference is checked to discriminate the front or rear face of the photographic film. That is, the infrared absorption spectrum is different between a base layer 18a and a gelatin layer 18b as shown in a graph where the infrared absorption spectrum of the base layer 18a is indicated by a solid line and that of the gelatin layer 18b is indicated by a dotted line. A reversal film whose front and rear faces are known is used to check preliminarily these two kinds of infrared absorption spectrum, and the infrared absorption spectrum coinciding with a measured that is selected to discriminate the front or rear face of a reversal film 18.

Title: Read-only memory
Inventor: SUMI SHINJI
IPC: G11C16/06
Filed: 1990-09-03
Abstract: PURPOSE:To speed up an operation time from the input of an address signal at the time of rising a word line selection signal (WL signal) to a sense amplifier output by providing a pull-down transistor between a data bus or a bit line and a low potential side power source. CONSTITUTION:A pull-down transistor N6 for connecting the data bus to a low potential side power source 2 is provided. Since a current always flows through a P channel transistor P1 by this pull-down transistor N6, at the time of rising the WL signal, the amount of the current flowing through the P1 is the sum of the amount of the current flowing through a memory cell N4 and the amount of the current flowing through the pull-down transistor N6. Therefore, the current flowing through the P1 increases by only the current flowing through a registor, and a current difference between the current flowing through the P1 and the half current (I REF) becomes larger, so the operation time of the sense amplifier becomes faster accordingly. Thus, an access time can be shortened.

Title: Motion vector prediction method for moving image
Inventor: KIM HYUN MUN
IPC: H04N19/139
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To selectively use the bilinear interpolations for calculation of motion vectors and to improve the computational complexity by not selecting only the motion vector of a current macro block as an initial motion vector and applying selectively the motion vectors which are obtained by applying the bilinear interpolations to the motion vector of a current block and also the motion vectors of the peripheral blocks of the current one. SOLUTION: An encoding estimation mode is decided after the motion vector of a current macro block is calculated for each integer (302S). Then a general search method is detected for an MPEG4 video VM, and the decoded precedent VOP is searched (303S). When (8×8) modes are selected, the motion search that is accordant with the characteristic of the macro block is performed more effectively than the VM via the calculation of the motion vector that is carried out by a simple bilinear interpolation. Furthermore, the blocking phenomena are significantly decreased since the local search is performed by the decoded precedent VOP which is actually used for compensation of the final motion.
