    摘要： A halftone display method utilizes an activation sequence, having a plurality of luminance blocks predefined in each frame or field to display an image and having redundancy, that enables one gray-scale level to be expressed by any one of a plurality of combinations of subframes (luminance blocks). When determining luminance blocks for use to display gray scale of an arbitrary first pixel, the luminance blocks to be used for the first pixel are selected in accordance with a predetermined rule, based on how the luminance blocks are used for a second pixel located in close proximity to the first pixel. In this way, by actively utilizing the redundancy of the activation sequence, the occurrence of moving-image false contours (false color contours) in video can be minimized, and also a motion compensation equalizing pulse method can be effectively applied to further improve the image display quality.

In addition, tracing is done to trace extract image data in the frame image data by using a simple motion vector detected for the frame image data of the motion picture data, a higher layer motion vector detector detects a motion vector of the frame image data by using the simple motion vector in common, and a compression encoder extracts the extract image data based on the results of tracing and compression-encodes it by using the motion vector.

    摘要： The present invention relates to an image processing apparatus and a method and a program that enable an amount of code to be suppressed below a desired value with more reliability. An emergency mode determining section 142 determines that the amount of code of a next picture is likely to exceed an upper limit if a target bit calculated by a rate controlling section 118 exceeds a predetermined upper limit. If it is determined that the amount of code of the next picture is likely to exceed the upper limit, the code amount controlling section 142 controls an orthogonal transducing section 114 to replace a transform coefficient of a predetermined frequency component with zero, controls an intra predicting section 125 to restrict intra prediction modes to be applied, and controls a mode determining section 127 to restrict inter prediction modes to be applied. The prevent invention can be applied to an encoding apparatus.
