Abstract: In an apparatus such as an optical mouse, a lens (14) images a surface (12) illuminated by a light source (10) onto an image sensor (16). The output of the image sensor (16) is read out and converted to digital format (18) and the digitised signal is processed (20) to derive motion information by correlation of successive frames. The input to the image processing (20) is passed through a high-pass filter (22).

Abstract: An orientation sensor (10) for use with an image sensor is provided, which comprises at least two polarisers (12, 14) with different orientations and associated photodetectors and signal processing means (20). The orientation sensor (10) can be incorporated in a digital camera. When the camera is exposed to daylight, which is polarised, the relative outputs from the differently oriented polarisers (12, 14) can be compared in order to record the orientation of the camera. This orientation can be stored with the image data so that a user does not have to manually change the orientation of an image on an image display device.

Abstract: An image plane consists of a number of pixels, two of which are shown. Each pixel comprises a photodiode and two transistors (M1, M2). Each pixel is connected by a signal bus (10) to a respective storage node located off the image plane. Each storage node comprises two capacitors (Csn_1, Csn_2) and associated switches (S2_1, S2_2). The transistor M2 applies a reset pulse to the pixel, and the transistor M1 connects the pixel to a given conductor of the signal bus (10) and thence to the storage node. The pixel transistors can be operated simultaneously, and the sensed values subsequently transferred from the storage nodes sequentially.

Abstract: An image sensor comprises an array of digital pixels and a first frame store for storing reference data and a second frame store for storing image data. The reference and image data are combinable to cancel the off-set of the pixels in the array. A re-set and a calibration phase are performed while a shutter is closed to obtain reference data during a calibration phase a comparator measures an off-set time to gather information on the pixels off-set. During or after an exposure phase a conversion time is measured representative of the illumination on the pixel. During the calibration phase only the off-set is measured. This digital technique requires a much smaller voltage swing on the pixel and known techniques and can therefore be performed in a shorter time which increases the overall frame rate of the image sensor as the time taken for the reset and calibration phases is less than the time take for the exposure phase.
