Abstract: An image processing circuit performs super-resolution (SR) operations. The image processing circuit includes memory to store multiple parameter sets of multiple artificial intelligent (AI) models. The image processing circuit further includes an image guidance module, a parameter decision module, and an SR engine. The image guidance module operates to detect a representative feature in an image sequence including a current frame and past frames within a time window. The parameter decision module operates to adjust parameters of one or more AI models based on a measurement of the representative feature. The SR engine operates to process the current frame using the one or more AI models with the adjusted parameters to thereby generate a high-resolution image for display.

Abstract: An image processing apparatus includes a super-resolution (SR) circuit and a resizer circuit. The SR circuit performs an SR operation upon a first image to generate a second image, wherein a resolution of the second image is not lower than a resolution of the first image, and the SR operation is based, at least in part, on one or more artificial intelligence (AI) models. The resizer circuit performs a resize operation upon the second image to generate a third image, wherein a resolution of the third image is not lower than the resolution of the second image, and no AI model is involved in the resize operation.

Abstract: A high accuracy satellite signal receiving controller and associated method is provided. The high accuracy satellite signal receiving controller includes a frequency synthesizer, and an analog-to-digital converter (ADC), a Global Positioning System (GPS) receiving module and a control unit. The frequency synthesizer, coupled to an external non-temperature-compensated crystal oscillator (non-TXCO), generates an oscillating frequency signal to the GPS receiving module. The ADC converts an analog temperature signal into a digital temperature signal. The control unit, coupled to the ADC, adaptively updates temperature/frequency offset data.
