Claim Text:
1. A bioinstrumentation apparatus comprising: a light irradiation unit irradiating a measurement region of a subject with light; a light detection unit detecting diffused light from the measurement region; and a computing unit computing a light absorption coefficient distribution inside the measurement region on the basis of an output signal from the light detection unit to generate a reconstructed image for the interior of the measurement region, wherein the computing unit calculates J coefficients w (where k is an integer from 1 to N, N is the number of times for carrying out iterative computation, x j (k) is a pixel value of the jth pixel on the kth iterative computation, and d j (k) is an update amount of the jth pixel on the kth iterative computation), thereby generating the reconstructed image.
