<p>The H.264/AVC standard has better coding efficiency comparing with former video coding standards. However, it still includes temporal artifacts, known as intra flicker.</p><p>In this paper, we propose intra flicker reduction method, which characteristic is to compensate average signal level of I picture in terms of macro block depending on the difference of average signal level of macro block between I picture and that of previous P picture. In detail, we propose 2 approaches to realize our idea. The first one is to implement our idea as post filter of decoder, which complies with the H.264/AVC standard. The second approach is to implement it in in-loop filter of both encoder and decoder, which requires a little change from the H.264/AVC standard. As our evaluation result, we confirmed that both approaches have efficiency to reduce intra flicker, 14.1[%] with the first approach, and 16.8[%] with the second approach, both as the maximum effect.</p>
