Description

本発明は、照明装置、及びプログラムに関する。 The present invention relates to a lighting device and a program .

本発明は、上記問題を解決すべくなされたもので、その目的は、照明対象を照明する照明光の照度や配光を可変にしつつ、装置を小型にすることができる照明装置、及びプログラムを提供することにある。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an illumination device and program capable of reducing the size of the device while changing the illuminance and light distribution of illumination light that illuminates the illumination target It is to provide.

本発明の一実施形態は、光量分布が設定された照明光を第１の方向で照明する照明部と、前記第１の方向から前記照明光を照明対象に照明する場合、前記照明対象の明暗分布が前記第１の方向とは異なる第２の方向から照明されたような明暗分布となる前記照明光の光量分布を示す第２光量分布情報と前記第２の方向とが関連付けて記憶されている記憶部と、前記第２の方向に関連付いた前記第２光量分布情報に基づいて前記照明部が照明する前記照明光の光量分布を設定する設定部とを備えることを特徴とする照明装置である。
また、本発明の一実施形態は、コンピュータに、光量分布が設定された照明光を第１の方向で照明する処理と、前記第１の方向から前記照明光を照明対象に照明する場合、前記照明対象の表面の明暗分布が前記第１の方向とは異なる第２の方向から照明されたような明暗分布となる、前記照明光の光量分布を示す光量分布情報に基づいて、前記照明光の光量分布を設定する処理とを実行させるためのプログラムである。
One embodiment of the invention, an illumination unit for illuminating the illumination light quantity distribution is set in a first direction, is illuminated from the first direction the illumination light to the illumination target, brightness of the illumination target Second light amount distribution information indicating the light amount distribution of the illumination light that is a light-dark distribution as if the distribution is illuminated from a second direction different from the first direction is stored in association with the second direction. a storage unit are, the lighting apparatus wherein the illumination unit based on the second light intensity distribution information had associate the second direction, characterized in that it comprises a setting unit for setting the light amount distribution of the illumination light that illuminates It is.
Further, according to an embodiment of the present invention, when the computer illuminates the illumination light with the light amount distribution set in the first direction, and illuminates the illumination light from the first direction on the illumination target, Based on the light amount distribution information indicating the light amount distribution of the illumination light, the light / dark distribution of the surface of the illumination target is a light / dark distribution as if illuminated from a second direction different from the first direction. This is a program for executing processing for setting a light amount distribution.
