Title: Process for skipping non-recording portion
Inventor: U JONG-SAM
IPC: G11B27/22
Filed: 1989-09-08
Granted: 1992-10-12
Abstract: A method for skipping the unrecorded area during playback  of a recording medium and playing back the recorded  area  at  normal speed involves electronically detecting the presence or absence of a recording signal, i.e. a sync. signal on the  recording  medium, causing playback of the recording medium to take place at a normal speed when the  sync.  signal  is  detected  by  a  microcomputer. Playback of the recording medium takes place at  high  speed  when the sync. signal is not detected. Accordingly, the  playback  time of the recorded areas is minimised. The power saving is achived by automatically switching power off when the playback is  completed, i.e., the sync. signal is not detected in a predetermined time.

Abstract: irradiation process is composed of, the first binary process, the lightening process, the second binary process, and  the  third binary process. The irradiation process includes  the  scan  of  a manuscript per pixel, conversion to the picture data, and storages a pixel value in a buffer. If the  present  pixel  value  of  said irradiation process is  brighter  than  the  first  inverse  value (Tmax), the first binary process binarizes the present pixel value to 'white'. In the case of the present pixel  value  being  darker than the second inverse value (Tmin),  the  first  binary  process binarizes the present pixel value to  'black'.  When  the  present pixel value is between the first  inverse  value  and  the  second inverse  value,  the  lightening  process  determines  the   local lighting difference  between  the  present  pixel  value  and  the lighting value in the black  window.  The  second  binary  process converts the present pixel value to 'white' if said local lighting difference value is less than the third inverse value.
