| description | PROBLEM TO BE SOLVED: To provide an image display device capable of reducing deterioration of picture quality in a case of performing compression processing and decompression processing of an image signal.SOLUTION: An image display device (projector 1) configured as an image display device for performing display based on an image signal includes: an image input part (image signal input part 30) to which the image signal is input; a first filter part 41 for performing filter processing for smoothing the image signal; a compression part 42 for compressing the smoothed image signal to generate compressed data; a storage part (frame buffer 43) for storing the compressed data; a decompression part 44 for reading and decompressing the compressed data stored in the storage part; a second filter part 45 for performing inverse filter processing of smoothing to the image signal decompressed by the decompression part 44; and a display part (image projection part 10) for performing display on the basis of the image signal subjected to the inverse filter processing by the second filter part.
【課題】画像信号の圧縮処理、解凍処理を行った場合に、画質の劣化を低減することが可能な画像表示装置を提供する。【解決手段】画像表示装置（プロジェクター１）は、画像信号に基づいた表示を行う画像表示装置であって、画像信号が入力される画像入力部（画像信号入力部３０）と、画像信号の平滑化を行うためのフィルター処理を行う第１フィルター部４１と、平滑化された画像信号を圧縮して圧縮データを生成する圧縮部４２と、圧縮データを記憶する記憶部（フレームバッファー４３）と、記憶部に記憶された圧縮データを読み出して解凍する解凍部４４と、解凍部４４によって解凍された画像信号に、平滑化の逆フィルター処理を行う第２フィルター部４５と、第２フィルター部により逆フィルター処理がなされた画像信号に基づいて表示を行う表示部（画像投写部１０）と、を備える。【選択図】図２ |
