Image recording device
An image recording device that compresses and records image data is provided wherein noise reduction is recursively performed on the non-compressed image signals and the feedback gain or the filtering characteristic of a recursive noise reduction circuit are controlled according to the compressibility of the image data in order to reduce the compressibility of the non-compressed image signals without deterioration or to improve the compressibility efficiency thereof and to reduce the digital value of the compressed image data with the frame noises in restraint.
