Latest Patents

Katayama's latest patents include an image processor, imaging device, and image processing system. The image processor features a multiplier that receives image data from a pixel section containing pixels of various colors. It multiplies the image data by an adjustment parameter that modifies the color level in each pixel. Additionally, an adjuster calculates the ratio of respective colors in each pixel and adjusts the value of the adjustment parameter based on this ratio. Furthermore, a binarization processor extracts a target image of a specific color based on the adjusted image data.

Another significant patent involves an arithmetic device and sensor designed to track the movement of objects between frames. This device reduces the scale of an arithmetic processing unit that performs calculations between frames in a sensor. A frame memory stores pixel data of a frame that transitions over time. The inter-frame arithmetic processing unit implements a predetermined arithmetic process in a column-parallel manner on the pixel data of the current and past frames, updating the past frame's pixel data based on the results of the arithmetic.
