Latest Patents

Kinumura's latest patents include an image processing system, image processing apparatus, image processing method, and storage medium thereof. This invention achieves a construction at low cost, which reduces the loss of gradation in dark portions of an image subjected to gamma correction according to the characteristics of a display. In his image reading apparatus, he enables finer reproduction of gradation in dark areas by reducing the number of gradations expressed by a signal obtained from a CCD. This is accomplished through non-linear gamma correction using a gamma coefficient below one, with the resulting signal transferred to a host computer. The computer then applies gamma correction using an inverse gamma coefficient, effectively canceling out the influence of the initial gamma correction.

Another notable patent involves a signal processing method, signal processing apparatus, and image reading apparatus. This invention processes visible light and infrared image signals obtained by illuminating a transparent document with light beams from both a visible light lamp and an infrared lamp. A histogram is generated based on the infrared image signal, and a threshold value is calculated. Infrared image signal components equal to or smaller than this threshold are extracted, and corresponding visible light image signal components are interpolated using surrounding visible light image signal components.
