Memory reduction device of stereoscopic image display for compensating crosstalk

摘要

A memory reduction device of a stereoscopic image display includes a compression unit configured to receive first to fourth input data belonging to Gn and comprised of K1 bit, respectively, align the first to fourth input data in order of a data size to generate first to fourth alignment data, generate first to fourth compression data groups including first and second compression data having K2 bits smaller than K1 bits and third compression data having K3 bits smaller than K2 bits based on the first to fourth alignment data, derive an outlier from the first to fourth input data by using a deviation between the first to fourth alignment data, select any one of the first to fourth compression data groups, as the compressed Gn−1 according to the presence or absence of the outlier and an outlier derivation position.

1. A memory reduction device of a stereoscopic image display for compensating for 3D crosstalk by comparing Gn and Gn−1 to be displayed to be adjacent to each other and modulating Gn into Gn′, the memory reduction device comprising:
a memory; and a compression unit configured to receive first to fourth input data belonging to Gn and comprised of K1 bits, respectively, align the first to fourth input data in order of a data size to generate first to fourth alignment data, generate first to fourth compression data groups including first and second compression data having K2 bits smaller than the K1 bits and third compression data having K3 bits smaller than the K2 bits based on the first to fourth alignment data, derive an outlier from the first to fourth input data by using a deviation between the first to fourth alignment data, select any one of the first to fourth compression data groups, as a compressed Gn−1 according to the presence or absence of the outlier and an outlier derivation position, and store the same in the memory, wherein each of K1, K2 and K3 is a positive integer, and wherein Gn is any one of left eye data and right eye data, indicating frame (or line data) of a 3D image to be displayed in an nth frame (or nth horizontal pixel line), and Gn−1 is the other of the left eye data and the right eye data, indicating frame (or line) data of a 3D image to be displayed in a (n−1)th frame (or (n−1)th horizontal pixel line).
