Latest Patents
Ueyama's latest patents include an innovative image acquisition apparatus. This apparatus features an optical system designed with distortion aberration characteristics that expand the central region while compressing the peripheral region. The imaging element within the apparatus converts the subject image into image data. A first memory stores filter factors used to interrupt spatial frequencies exceeding the Nyquist frequency of the image data. Additionally, a second memory defines the outer edge of a Nyquist image region. The filter factor setting circuit assesses each pixel position of the image data to determine its inclusion in the Nyquist image region, subsequently reading the appropriate filter factors. The filter circuit then processes the image data according to these factors, while a distortion correcting circuit addresses the distortion aberration characteristics.
Another significant patent involves a variable resistance circuit and its applications. This circuit is capable of offsetting variances in the manufacturing of integrated circuits and the influence of ambient temperatures. It includes a control circuit with multiple constant-current output terminals, where the constant current ratio is adjustable via signals applied to a control terminal. The design incorporates an operational amplifier, a resistor, and several MOS transistors, ensuring precise control and functionality.
