Summary:PROBLEM TO BE SOLVED: To make it possible to increase the speed of processing to determine the type of image data and accurately determine the type of the image data.SOLUTION: A terminal device supplies image data to a projector, and comprises: a terminal communication part that transmits the image data to the projector; an image data creation part 204 that creates comparison result image data indicating a result of comparison between the image data before update and the image data after update; and a determination part 205 that determines the type of the comparison result image data. The determination part 205 divides the comparison result image data into a plurality of areas, performs determination on part of pixels for each of the areas obtained through the division, and makes the positions of the pixels in the first area used for determination in the first area different from the positions of the pixels in the second area used for determination in the second area.SELECTED DRAWING: Figure 2 【課題】画像データの種類の判定の処理速度を向上し、正確に画像データの種類を判定できるようにすることを目的とする。【解決手段】プロジェクターへ画像データを供給する端末装置であって、プロジェクターへ画像データを送信する端末通信部と、更新前画像データ、及び、更新後画像データを比較した結果を表す比較結果画像データを生成する画像データ生成部204と、比較結果画像データの種類を判定する判定部205と、を備え、判定部205は、比較結果画像データを複数の領域に分割し、分割した領域ごとに一部の画素について判定を行い、第1の領域において判定に用いられる第1の領域における画素の位置と、第2の領域において判定に用いられる第2の領域における画素の位置と、を異ならせる。【選択図】図2
