Latest Patents

Mitsunami's latest patents include an arithmetic apparatus and a control method utilizing the CORDIC algorithm. This arithmetic apparatus consists of multiple cascade-connected arithmetic units. Each unit features a calculator that operates in either a rotation mode for performing rotation calculations or a vectoring mode for calculating rotation angles. Additionally, a holding unit retains rotational direction information during the vectoring mode. When in rotation mode, the calculator executes rotation calculations based on data from a preceding arithmetic unit, using the held rotational direction information.

Another significant patent involves an information processing apparatus and its control method, particularly for video cameras. This apparatus deduces a homography matrix that represents the geometrical relationship between two images. It achieves this by obtaining a transformation matrix for four feature points in each image based on reference coordinates. The apparatus calculates the area of a triangle formed by three of the four feature points and derives projective parameters for transformation matrices from the area ratios. Ultimately, it computes the homography matrix by multiplying one of the obtained matrices with the inverse of the other.
