Abstract: In certain embodiments, an input device includes a housing, a processor disposed in the housing, and an image sensor to track a movement of the input device with respect to an underlying surface. The image sensor includes a pixel array and operates in two modes of operation including a first mode of operation where the processor causes the image sensor to utilize a first plurality of pixels in the pixel array when tracking the movement of the input device or a second mode of operation where the processor causes the image sensor to utilize a second plurality of pixels in the pixel array when tracking the movement of the input device, where the second plurality of pixels has fewer pixels than the first plurality of pixels.

Abstract: Methods and systems for determining a displacement of a peripheral device are provided. In one example, a peripheral device comprises: an image sensor, and a hardware processor configured to: control the image sensor to capture a first image of a surface when the peripheral device is at a first location on the surface, the first image comprising a feature of the first location of the surface; execute a trained machine learning model using data derived from the first image to estimate a displacement of the feature between the first image and a reference image captured at a second location of the surface; and determine a displacement of the peripheral device based on the estimated displacement of the feature.

Abstract: A method of operating a computer mouse includes receiving electromagnetic (EM) radiation emitted from a source external to the computer mouse, the received EM radiation induces noise within one or more bands of noise frequencies and an image sensor circuit of the computer mouse generates erroneous movement detection signals in response to an operating frequency of the image sensor circuit being within the one or more bands of noise frequencies. The method further includes determining the operating frequency of the image sensor circuit, comparing the operating frequency to a target frequency, wherein the target frequency is outside of the one or more bands of noise frequencies, and tuning the operating frequency of the image sensor circuit towards the target frequency.
