IMAGING APPARATUS IN WHICH REDUCED RESOLUTION IMAGE DATA IS GENERATED, AND WHEN SUPPLIED OVER AN IMAGE DATA BUS, THE RESOLUTION IS INCREASED AND OUTPUTTED

摘要

IN AN IMAGING APPARATUS, AN IMAGE IS TO BE DISPLAYED IN REAL-TIME ON A FINDER. IN THE FINDER MODE,A CCD INTERFACE (21A) THINS OUT HORIZONTAL COMPONENTS OF IMAGE DATA SUPPLIED FROM AN IMAGE GENERATING UNIT (10) TO ONE-THIRD AND ALSO EFFECTS GAMMA CORRECTION ETC TO SEND THE RESULTING IMAGE DATA A CAMERA DSP (21C). THE CAMERA DSP (21C) EFFECTS DATA CONVERSION AND RESOLUTION CONVERSION ON THE IMAGE DATA RESULTING FROM THE THINNING TO CONVERT THE DATA INTO Y, CB AND IMAGE DATA WHICH IS ROUTED TO A MEMORY CINTROLLER (22). THE MEMORY CONTROLLER (22) WRITES THE IMAGE DATA IN THE IMAGE MEMORY (32) AND READS OUT THE DATA FROM THE MEMORY CONTROLLER 22 TO ROUTE THE READ-OUT DATA OVER AN IMAGE DATA BUS (33) TO AN NTSC/PAL ENCODER (23) CONVERTS THE IMAGE DATA IN RESOLUTION AND FURTHER CONVERTS THE IMAGE DATA INTO DATA OF THE NTSC OR PAL SYSTEM TO ROUTE THE RESULTING DATA TO A FINDER.FIGURE 3
