Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] see figure 1 Shown is the internal structure diagram of the TV set applying the present invention, the method of the present invention can be solidified and integrated into the data processing chip of the TV set through the program, so as to realize the processing of image data, and transmit the processed image data to related chips , to perform subsequent processing steps.

[0026] For plasma TV sets, there are multiple technologies at present, and the method of the present invention can be applied to technologies such as ACPDP, DCPDP or SM-PDP. The following embodiment one takes ACPDP as an example to describe the flow process of the method of the present invention in detail. In the example, 256 linear gray levels are taken as an example for illustration. see figure 2 The flow chart of the illustrated embodiment 1 includ...

Abstract

The invention provides a method and a device for processing image data. The invention comprises the following steps that: the linear gray scale of a current pixel point is obtained, the similarity scale value of the linear gray scale in the preferred linear gray scales is operated, the scale value corresponding to the same position of a screen with the current pixel point is obtained in a masking, the similarity between the similarity scale value and the scale value is operated, one preferred linear gray scale is chosen from the preferred linear gray scales to replace the linear gray scale according to he similarity, the chosen preferred linear gray scale is used for implementing the subsequent encoding processing. The invention chooses little linear gray scale to realize much gray scale display and can satisfy the requirement of the image display when solving the false contour phenomenon.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method and device for image data processing. Background technique [0002] With the development of society, the TV sets used by users are in the transition stage from CRT monitors to plasma monitors. Since the TV sets used by users at first are all CRT monitors. [0003] Although many users have already used plasma displays, in the current image and video transmission signals, in order to make up for the nonlinearity of the electro-optic conversion of CRT displays (that is, the grayscale brightness density displayed by CRT displays and the input grayscale value have a nonlinear relationship) ) and correct the gamma algorithm before the image video signal is transmitted. Therefore, the plasma display needs to perform inverse gamma correction on the image and video signals, so that the gray scale of the image displayed by the plasma display is consistent with the gray sca...
