Abstract: Provided is an electronic apparatus including a memory; a sensor; a projection part configured to output an image onto a projection surface, and at least one processor configured to: obtain a first image including a content, obtain inclination information of the electronic apparatus using the sensor, identify a first area in which the first image is displayed and a second area in which the first image is not displayed based on the inclination information, change a size of the first image based on the size of the first area, control the projection part to output the first image having the changed size onto the first area, and control the projection part to output, onto the second area, a second image including additional information based on the inclination information and a size of the second area.

Abstract: A hybrid coder, for performing interframe video encoding which combines the advantages of both the interfield and the interframe codings for low bit-rate video transmission; the pel elements of a differential block from a subtracter is rearranged; the complexity of a present input block and the horizontal motion vector thereof are estimated; and, then, one of the differential block and the rearranged block is subjected to a two-dimensional transform according to the complexity and the horizontal motion vector.

Abstract: An interframe video encoder of the type known as a hybrid coder, combines the advantages of both the interfield and the interframe codings for low bit-rate video transmission. The pel elements of differential block from subtracter are rearranged and the correlation of the rearranged block is estimated. The correlation of the differential block is also provided. And then, one of the differential block and the rearranged block is subjected to two-dimensional transform according to the comparsion of the correlations.
