Inventor: TERASHITA TAKAAKI
IPC: G03B27/80
Filed: 1989-07-20
Abstract: PURPOSE:To decide accurate exposure by performing normalization in accordance with a transformation condition decided based on accumulated data and selecting the photometric data of three colors for deciding the exposure. CONSTITUTION:The photometric data of three colors which is measured by a photometer 28 is fetched and mean mask density stored in a memory 34 is used to arithmetically operate the photometric data of the low density part of three colors, which is stored in the memory 34. Then, a value which is larger than the mean mask density by a specified value alpha is compared with the density value which is the lowest in the photometric data of three colors or the mean value of the photometric data of three colors. When the former>the latter, the density value which is the lowest in the photometric data of three colors or the mean value of the photometric data of three colors in set as the photometric data of the low density part. Meanwhile, when the former<the latter, the vale which is larger than the mean mask density by the specified value alpha is set as the photometric data of the low density part. Thus, the exposure is accurately controlled.

Title: Voice understanding device
Inventor: NOGUCHI ATSUSHI
IPC: G10L15/18
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To obtain a voice understanding device, which obtains a correct key word even though a necessary key word exists not only in one recognition result candidate but also exists in plural recognition result candidates. SOLUTION: A voice recognition section 101 outputs plural recognition result candidate sentences obtained as a recognition result and scores of each word included in each candidate sentence. A meaning extracting section 104 discriminates whether the key word exists in the plural recognition result candidate sentences outputted from the section 101 or not based on the stored contents of a conversation control section 106 and a meaning expression storage section 107 and outputs the key words existent in these sentences to a meaning output section 105. The section 104 selects a best score outputted by the section 101 for each key word when plural key words, which should not simultaneously exist in one uttering, exist.

Abstract: PURPOSE: To improve operation feeling by computing operation characteristic at the time of accelerator operation, on the basis of a detection signal for an accelerator operation variable, and using a calculation result for learning and correcting target opening characteristic for throttle opening, depending on the accelerator operation variable. CONSTITUTION: When acceleration status is identified at a step 16, an actual accelerator operation speed dsAim from a first acceleration operation variable SAim to an 'i'-th accelerator operation variable SAim is computed at a step 17. and a mean operation variable SAim for an accelerator operation variable SA during acceleration is computed at a step 18. Then, an operation speed dSA at the mean operation variable SAim is read out from an operation speed characteristic map at a step 19. Thereafter, a reference operation speed dSA and an actual accelerator operation speed dSAim are compared to give a speed ratio dSAy at a step 20. Then, the ratio dSAy is weight averaged for the previous learning correction value KLim-1, and a learning correction value KLim is obtained for updating the previous value and saved at a step 21.  Thereafter, the value KLim is used to correct a target opening of throttle opening as opening corresponding to accelerator operation tendency.
