According to an embodiment of the disclosure, an electronic apparatus may include: a display configured to display an image; and a processor configured to: adjust, for each of sub areas having a specified size in an image quality degradation anticipation area of an image, a pixel value of at least one adjustment pixel among a plurality of pixels included in each sub area, and change the adjustment pixel into another pixel among the plurality of pixels, while maintaining a representative value of the plurality of pixels included in each sub area.

The invention provides methods and related apparatuses for reducing an edge effect in an image displayed on an electrophoretic display having an array of pixels by displaying an image made up of a plurality of pixels on a first subset of the array of pixels and shifting the value of each image pixel by one position in a first horizontal direction and a first vertical direction such that the image is identical but shifted in position to a second subset of the pixel array. The method also includes shifting the value of each image pixel by one position in a second horizontal direction and a second vertical direction where the second horizontal direction is opposite the first horizontal direction, and the second vertical direction is opposite the first vertical direction, whereby the image displayed is identical but shifted in position back to the first subset of the array of pixels.

In a projection-type display device including a liquid crystal panel where panel pixels are arranged in a first direction and a second direction, the polarity of the image signal supplied to each of all panel pixels is set to the same polarity in the same unit period among a plurality of unit periods, and the polarity of the image signal is reversed upon transition from the current frame period to the next frame period. The polarity of the image signal is reversed when a projection pixel is shifted by a light path shifting element unit in the first direction or in the second direction upon transition of the unit period, and the polarity of the image signal is not reversed when it is shifted along a third direction or a fourth direction that intersects the first direction and the second direction.

An optical device including a holder and a light transmissive plate is provided.
