1. Field of the Invention
The present invention relates to an image processing apparatus with enlarging function for electronic enlargement of a designated area within the image field.
2. Related Background Art
FIG. 1 is a block diagram of a conventional image pickup device;
FIGS. 2A to 2D are views illustrating an electronic image enlarging process;
FIG. 3 is a block diagram of an enlargement process circuit in the image pickup device shown in FIG. 1;
Now the present invention will be clarified in detail by preferred embodiments thereof shown in FIGS. 4 to 15.
At first a first embodiment of the present invention will be explained with reference to FIGS. 4 to 6. FIG. 4 is a block diagram of an image pickup apparatus constituting a first embodiment of the present invention, wherein components same as those of the conventional configuration shown in FIG. 1 are represented by same numbers. The configuration shown in FIG. 4 is different, from that shown in FIG. 1, in the addition of an enlargement position input device (means) 20, an enlargement ratio setting device 21 for setting the enlargement ratio, an enlargement position display circuit 22 and an electronic view finder (EVF) 23 constituting the display means.
The enlargement position input device 20 is provided for enabling the photographer to input positional information indicating the position of execution of the enlargement process by the enlargement process circuit 5. The enlargement ratio setting device 21 is provided for enabling the photographer to input the enlargement ratio, at the enlargement process by the enlargement process circuit 5. The enlargement position display circuit 22 displays the positional information, input from the enlargement position input device 20, on the image area of the electronic view finder (EVF) 23. The EVF 23 constitutes monitor means for the photographer to monitor output image signals output from the D/A converter 7 and an anticipated enlargement position signal output from the enlargement position display circuit 22.
