Image signal recording apparatus capable of recording compressed image data together with audio data

An image and audio signal recording apparatus in which image data of an image signal produced by imaging means is recorded in a recording medium together with audio data of an audio signal collected by audio collecting means comprising:

• blocking means for dividing the image data and the audio data into blocks;
• common orthogonal transform means for achieving an orthogonal transform on the image data and the audio data respectively blocked by said blocking means;
• and
• single coding means for compressing and for coding the orthogonally transformed image data and the audio data, respectively;
• recording code generator means for producing recording codes associated with amounts of the image data and the audio data to be recorded in the recording medium;
• data input/output control means for writing the image data in a first area of said recording medium and for writing the audio data in a second area of said recording medium and for controlling write and read operations of the recording codes produced by said recording code generator means in said recording medium;
• and
• recording medium remainder display means for displaying a remaining amount of the first area and the second area in said recording medium available for a recording operation;
• said data input/output control means reading out the recording codes stored in said recording medium so as to cause said recording medium remaining display means to display the remaining amount of the first area and the second area available for a recording operation.
