1. A data processing method for use in a display apparatus for storing input video data and outputting display data based on the stored video data to display means, comprising the steps of:
- changing a relationship between the video data and the display data in response to a driving condition set by setting means for setting the driving condition for said display means, wherein the video data is data with a frame consisting of a plurality of field;
thinning the video data in units of fields and converting into the display data for said display means driven at a frame frequency lower than that of the video data, and reading out, and subjecting the video data to at least one of a pseudo halftone processing or γ
-correction per frame.

Abstract
A data processing system that allows satisfactory display even when the driving condition changes. The data processing system includes a display device, a video data memory which stores video data in which one frame consists of a plurality of fields, and a display data memory which stores display data to be displayed on the display device. A setting unit sets the driving condition for the display device, and thins the video data in units of fields.
