And a left-eye image acquisition unit 102 that acquires an image.
- the right eye image acquisition unit 101, or the right eye image acquisition unit 101 and the left eye image acquisition unit 102 performs enhancement processing on a predetermined band of the input image.
- the difference (enhancement difference) is more than the detection limit.
- the input image may be a still image or a moving image.
- the emphasis process is performed on one of the left and right images with an emphasis amount different from that of the other emphasis process, thereby causing a visual field conflict, improving the contrast, and improving the image quality.
- the band enhancement processing may be performed only by the right eye image acquisition unit 101, or the band enhancement processing is performed by both the right eye image acquisition unit 101 and the left eye image processing unit 102, and the enhancement amount in the band enhancement processing is performed. May be different.
- the difference between the enhancement amounts of the right eye image and the left eye image is 0.1 or more and the enhancement amount is ⁇ 0.1 to 10 respectively.
- the enhancement amount of the band enhancement process may be changed according to time. Further, as will be described later, monochrome inversion processing or color inversion processing may be performed on either the right eye image processing unit or the left eye image processing unit instead of the band enhancement processing.
- band enhancement processing black-and-white reversal, or color reversal processing may be performed only on the attention area specified in the input image.

Specifically, enhancement processing is performed using a value of the enhancement amount k different from that of the right-eye band enhancement unit 4, and a left-eye band enhancement image having a different enhancement amount from the right-eye band enhancement image is generated. This improves the contrast and improves the image quality.
- Y (x, y) represents the luminance value at the coordinate (x, y) point in one frame of the original image.
- K in the formula (1) is an enhancement amount, and sharpness increases as it increases from 0, and sharpness decreases as it decreases from 0.
- the BPF is a band-pass filter that filters band components sensitive to visual sharpness.

However, when the sharpness is increased in a normal use situation, it is desirable that there is a difference of 0.1 or more as the value of the enhancement amount k experimentally in order to perceive the difference in sharpness. When the difference in enhancement amount k (enhancement difference) is smaller than 0.1, it becomes difficult to distinguish the difference in sharpness. The limit point where the difference in sharpness can be discriminated by perception is called the detection limit. Sharpness increases as k increases, but when a certain level is exceeded, black and white bordering occurs near the edge due to excessive enhancement, resulting in a picture-like image rather than a real image.
- FIG. 3 is an explanatory diagram showing the relationship between the enhancement amount k and the sharpness.
- the sharpness characteristic curve 201 indicates that the sharpness increases in proportion to the enhancement amount up to a certain amount, but if the enhancement is excessive, the sharpness can no longer be sensed and decreases.

In order to make humans perceive a reduction in sharpness experimentally, it is desirable that the enhancement amount be ⁇ 0.1 or less.
- the lower limit of k when reducing sharpness is -1.0, that is, when all band components are subtracted. If k is set to a value smaller than ⁇ 1.0, an unpredictable image effect will occur. That is, when one enhancement amount is set to 0 and the other sharpness is reduced, the enhancement amount is preferably ⁇ 1.0 ⁇ k ⁇ ⁇ 0.1.

Specifically, a process of translating each pixel in accordance with the depth of each pixel of the image is performed. For example, for an object in the distance, the movement amount is set to 0, and an image obtained by moving the region pixel of the nearby object X by d in the horizontal direction and a right eye band emphasized image are displayed on both eyes. By doing this, the object X can appear to be raised.

次に、発明の第2の実施の形態について説明する。本実施の形態は、視野闘争を生じさせるための補正処理として帯域強調処理を施す例である。ここでは先ず、本実施の形態にかかる画像処理装置において、質感が変化して画質が向上する原理について説明する。大山、今井、和気編、"感覚・知覚心理学ハンドブック"、誠信書房、pp.744-751(非特許文献1)によると、左右の目に異なる画像を提示すると、脳内ではこれらの画像が合成されて知覚される。その知覚状態は安定ではなく、どちらかの画像が支配的に見えたり、両眼の画像が交互に見えたりする。この現象は視覚心理学において視野闘争とよばれる。
次に、本発明の第3の実施の形態について図面を参照して詳細に説明する。本実施の形態は、第1の実施の形態の帯域強調処理において、強調量を時系列に変動させる例である。図14は、本発明の第3の実施の形態にかかる画像処理装置を示すブロック図である。図14に示すように、第3の実施の形態にかかる画像処理装置120は、多眼画像表示部11と、右眼帯域強調部13と、左眼帯域強調部14と、右眼強調量時系列変動部15と、左眼強調量時系列変動部16と、注目領域指定部12と、視差生成部19とを有する。多眼画像表示部11は、右眼画像表示部17と、左眼画像表示部18とを有する。
