A system and a method related for evaluation of sport ball data. The method includes calibrating a first coordinate system of a first camera to a second coordinate system of a baseball field; capturing, with the first camera, one or more images including a first batter; determining biometric characteristics of the first batter based on the one or more images and the calibration of the first camera to the baseball field; mapping the biometric characteristics of the first batter to an upper positional limit and a lower positional limit of a first strike zone for the first batter; and determining positional limits of the first strike zone in the second coordinate system.

A decoding device includes a controller classifying a bitstream as a first bitstream and a second bitstream based on a plurality of blocks defined by a matrix and included in a frame, a first decoder including a first processor performing decoding on the first bitstream and outputting first decoding data and a first memory, a second decoder including a second processor performing decoding on the second bitstream and outputting second decoding data and a second memory, a first buffer transmitting the first decoding data to the second memory, and a second buffer transmitting the second decoding data to the first memory. The first processor controls the second memory to store the first decoding data, and the second processor controls the first memory to store the second decoding data.

A user's eyes and if desired head is tracked as the user's gaze follows a moving object on a display. Motion blur of the moving object is keyed to the eye/head tracking. Motion blur of other objects in the frame also may be keyed to the eye/head tracking.

A method for calibrating a photodetector array supplying a video stream includes: a determination step, wherein an offset table is determined for each current image of the video stream based on at least two corrections from among the following: a first correction from a comparison of the current image to a corresponding predetermined reference table; a second correction from a calculation of a column error of the current image; and a third correction from a high-pass temporal filtering of the video stream; and a calculation step, wherein a current value of an offset table, equal to a sum between a previous value of the offset table and a weighted sum of at least two corrections, is calculated, with each coefficient of the offset table being associated with a respective photodetector of the array.
