Title: Phase noise type wide spectral band width optical low-pass anti-aliasing filter
Inventor: HIRSH JEFFREY I
IPC: H04N9/07
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To restrain aliasing artifact at low cost over a wide spectral range by providing material for forming a transparent substrate and plural transparent spots and satisfying a specified condition. SOLUTION: The spots are irregularly arranged on the substrate for making a phase difference between a light wave front transmitted through the spot and a part other than the spot of the substrate, and the phase difference satisfies the condition ϕO=π. In such a case, ϕO is the phase difference caused by the spot in specified wavelength λO satisfying λB<=λO<=λR, and it is given by an expression I and has feature shown by an expression II. In the expression, nO means a refractive index in the specified wavelength λO of the material forming the spot, nO' means the refractive index in the specified wavelength λO of a medium surrounding the spot, and (t) means the physical thickness of the spot. Thus, the filter is suitable for the use in a solid-state camera performing discrete image sampling.

Abstract: PROBLEM TO BE SOLVED: To improve cleanliness of exhaust gas and fuel efficiency by calculating valve timing control amount based on advance angle amount and target advance angle amount both calculated via calculation means and thus controlling to reduce valve-overlapped amount if a combustion state immediately after an engine started is unstable. SOLUTION: When an internal combustion engine 1 is in operation, a present advance angle amount which is a phase difference between a cam angle sensor 15 and crank angle sensor 13 is calculated by an ECU 25.

A target advance angle amount is calculated, until the elapsed time after the engine started reaches a prescribed value, by means of the second map in which a region with small target advance angle amount settings is large, rather than by means of the first map used for calculating a target advance angle amount in a normal condition.  The valve timing control amount is calculated based on the present advance angle amount and target advance angle amount calculated thereby, enabling reducing valve-overlapped amount if a combustion state immediately after the engine started is unstable.
