Image data processing apparatus and method of processing image data

---

Abstract

---

The brightness characteristic detection circuit 1 divides the frame 21 into a plurality of pixel blocks 22, detects average brightness characteristics of respective pixel blocks, and obtains the maximum or minimum brightness value of input image data from the average brightness characteristics of the pixel blocks. Correcting input image data with correction parameters set in accordance with the detected maximum or minimum brightness value generates display data. Even if a noise is incorporated in the image data, the influence of the noise is suppressed and the image data may be processed accurately.
