Abstract
According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for binocularly displaying visual content as a first image directed towards a first eye of a user and as a second image directed towards a second eye of the user. The first image comprises a first area in which a blue spectral component of the visual content is reduced as compared to a corresponding first area of the second image. The second image comprises a second, different area in which a blue spectral component of the visual content is reduced as compared to a corresponding second area of the first image.
Claims20
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- binocularly display visual content as a first image directed towards a first eye of a user and as a second image directed towards a second eye of the user;
- wherein the first image comprises a first area in which a blue spectral component of the visual content is reduced as compared to a corresponding first area of the second image;
- wherein the second image comprises a second area in which a blue spectral component of the visual content is reduced as compared to a corresponding second area of the first image;
- and
- wherein the first area and the second area are determined based on mirror-image filters applied to the first image and the second image.
A method comprising:
- binocularly displaying visual content as a first image directed towards a first eye of a user and as a second image directed towards a second eye of the user,
- wherein the first image comprises a first area in which a blue spectral component of the visual content is reduced as compared to a corresponding first area of the second image,
- wherein the second image comprises a second area in which a blue spectral component of the visual content is reduced as compared to a corresponding second area of the first image;
- and
- wherein the first area and the second area are determined based on mirror-image filters applied to the first image and the second image.
A non-transitory computer readable medium comprising program instructions stored thereon for causing an apparatus to perform at least the following:
- binocularly display visual content as a first image directed towards a first eye of a user and as a second image directed towards a second eye of the user,
- wherein the first image comprises a first area in which a blue spectral component of the visual content is reduced as compared to a corresponding first area of the second image,
- wherein the second image comprises a second area in which a blue spectral component of the visual content is reduced as compared to a corresponding second area of the first image;
- and
- wherein the first area and the second area are determined based on mirror-image filters applied to the first image and the second image.
