Abstract: [Problem] To provide a color conversion method, a gray scale value correction apparatus, a computer program and a display apparatus that can reproduce fine gray scale variations between grid points and further can suppress the deterioration of accuracy caused by interpolations. [Solution] One of the input or output gray scale of a gray scale characteristic, which indicates an input/output gray scale characteristic to be reproduced at a second conversion unit, is sectioned into gray scale sections each having a given gray scale interval. Each gray scale value of the other gray scale of the gray scale characteristic is corrected for a respective gray scale section such that the intervals of the other gray scale that are of the gray scale sections as sectioned become intervals each corresponding to the given gray scale interval. A first conversion unit uses the corrected gray scale values to convert the gray scale values of an image.

Abstract: Provided are a method for measuring display light intensity, a computer program, and a measurement system whereby color expression can be generically measured without regard to the specifications of the display device. A measurement device (1) connected to an optical sensor (2) is capable of communicating with a display device (information terminal device (3)) that is the object of measurement, and transmits content including a color patch to the display device to cause the content to be displayed, and performs measurement using the optical sensor (2) during display. In order to perform measurements using numerous color patches, the measurement device (1) repeats a process whereby, when the measurement performed during display of one color patch is completed, content including another color patch is transmitted to and displayed on the display device, and measurement is performed during display.
