Abstract
An image coder includes an input unit for inputting an image signal, a coding unit for coding the image signal by adaptively switching a first coding mode for performing intraframe coding and a second coding mode for performing interframe coding, and a command unit for outputting a command to the coding unit to forcibly execute the first coding mode. The command unit outputs a command at intervals controlled in accordance with the quantity of coded data generated when the image signal is coded. Alternatively, the image coder includes an input unit for inputting an image signal, a detection unit for detecting the activity of the image signal input by the input unit, a coding unit for coding the image signal by adaptively switching a first coding mode for performing intraframe coding and a second coding mode for performing interframe coding, and a command unit for outputting a command to the coding unit to forcibly execute the first coding mode. The command unit outputs a command at intervals controlled in accordance with an output from the detection unit.
