IPC: G01M11/00
Filed: 2003-01-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a response characteristics measuring instrument that can accurately measure the response characteristics of an object to be measured by using a light source, such as the superhigh-pressure mercury lamp etc., by solving the problem that the measurement of response time becomes difficult due to the ripple component contained in the light emitted from the light source.  <P>SOLUTION: The light emitted from the light source 1 is converged to a liquid crystal panel 4 through a condensing optical system 3 and transmitted through the panel 4. Then the converged light transmitted through the panel 4 and having a changed angle of rotation is again transmitted through an analyzer 11 and converged to a photodetector 13 through another condensing optical system 12. The photodetector 13 outputs a voltage signal to an electronic circuit 8 in accordance with the intensity of the detected light and the voltage signal is measured as time series data together with another voltage signal based on the detection of reflected light produced by a half mirror 5. Then this measuring instrument measures the accurate response characteristics of a liquid crystal element by removing the ripple component contained in the light emitted from the light source by dividing the voltage signal supplied from the photodetector 13 by the voltage signal supplied from another photodetector 7.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Image expansion device and electronic camera
Inventor: KUROIWA TOSHIHISA
IPC: H04N19/423
Filed: 2003-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To easily reproduce a thumbnail image of a file recorded by another camera.  <P>SOLUTION: This image expansion device has an expansion part for expanding compressed image data, a detection part, a calculation part, a replacement part and a transfer instruction part. The detection part detects an address of a start code indicating a staring position of an expanding operation of the image data in a memory. The calculation part calculates an address of a starting point of DMA transfer before the address of the start code. The replacement part replaces data between the start code and the starting point of DMA transfer in the memory with data for replacement. The transfer instruction part performs the DMA transfer of the data for replacement and the image data from the memory to the expansion part. Since reading of the data for replacement is skipped by the expansion part, it becomes equivalent to a fact that the leading address of SOI of the thumbnail image is transferred as the starting point of DMA transfer. Consequently, the thumbnail image of the file recorded by other camera can also be easily expanded.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
