Abstract:
An image coded data re-encoding apparatus which receives a first image coded data and which generates a second image coded data by performing a digital signal processing on said first image coded data, said first image coded data generated by a coding processor including a transformer, a quantizer, and a variable length coder for coding the digital input image signal, said image coded data re-encoding apparatus comprising:an image coded data analyzer for generating coded data after signal processing by performing a first digital signal processing on said first image coded data which partially decodes said first image coded data; and an image coded data synthesizer for generating said second image coded data by performing a second digital signal processing on said coded data after signal processing which re-encodes said coded data after signal processing based on multiple signals associated with said first image coded data by using said coded data after signal processing output from said image coded data analyzer and said multiple signals.
