An acoustic air impingement drying system is provided for drying a material. The output from the CCD is input, through an AD converter and the like, to an AE processor circuit for performing an auto-exposure control processing and an AF processor circuit for obtaining an evaluation value for auto-focusing through a gate circuit. Also, the method includes receiving a request to send the representation of the television program to a handheld device. The user can adjust just the chroma of the desired color.
