Abstract: An apparatus and method for performing variable length coding (VLC) within an adaptive entropy image coding process are presented. VLC is performed using a progressive coding technique, such as progressive Golomb coding (PGC) whose operation is based on a set of parameters. Grouping is performed within image distribution contexts, such as number of quantized bit planes (qn), previous residual, predictor type, and color, so that each group having similar contexts is associated with a set of progressive coding parameters. The grouping can be performed on-line or off-line. In operation, the progressive coding parameters then change in response to changing image distribution contexts toward optimizing image coding, such as increasing peak signal-to-noise ratio (PSNR).

The artifacts represent a thing to be learned by the animal and from which the animal can interpret the thing that is to be learned. Artifacts are received from the animal through a device. The received artifacts represent whether the animal has learned the thing. The artifacts are interpreted to infer an extent to which the animal has learned the thing. The animal is rewarded through a device based on the extent to which animal has learned the thing.

Abstract: An image sensor may include phase detection pixels that receive and convert incident light into pixel signals. Processing circuitry may use pixel signals from the phase detection pixels to determine an amount by which image sensor optics should be adjusted during automatic focusing operations. Phase detection pixels may include photodiodes with asymmetric angular responses. For example, the center of a photodiode in a phase detection pixel may be offset from the optical center of the microlens that covers that photodiode. A group of two, three, four, or more than four phase detection pixels may be clustered together and covered by a single microlens. Groups of these clusters may be arranged consecutively in a line. Phase data may be gathered using all of the phase detection pixels in the array, and image processing circuitry may determine which phase data to use after the data has been gathered.
