Abstract
Abstract An image sensing apparatus is provided with an image sensor; an electronic monitor having a number of scanning lines fewer than the vertical picture elements of the image sensor; and a driving circuit driving the image sensor with a fewer number of scanning lines when the apparatus is in a monitor mode than in an image sensing mode. The driving circuit is arranged to drive the image sensor in a non-interlacing manner in the monitor mode.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
183 words
An image monitor-displaying apparatus, comprising: image sensing means for sensing an image of an object and for generating an image signal corresponding to said object; output control means for outputting the image signal from said large sensing means on the basis of either a first output mode in which the image signal having a first resolution is outputted from said image sensing means or a second output mode in which the image signal having a second resolution lower than said first resolution is outputted from said image sensing means; monitor-displaying means for displaying the image signal outputted from said image sensing means on the basis of said second output mode; and displaying operation control means for giving an instruction to said output control means to effect an operation based on said first output mode without effecting a display by said monitor-displaying means, and for giving an instruction to said output control means to effect an operation based on said second output mode so as to output an image signal to produce the above-mentioned second resolution, while effecting a display by said monitor-displaying means.
Claim 2
Dependent Claim
183 words
An image monitor-displaying apparatus, comprising: image sensing means for sensing an image of an object and for generating an image signal corresponding to said object; output control means for outputting the image signal from said large sensing means on the basis of either a first output mode in which the image signal having a first resolution is outputted from said image sensing means or a second output mode in which the image signal having a second resolution lower than said first resolution is outputted from said image sensing means; monitor-displaying means for displaying the image signal outputted from said image sensing means on the basis of said second output mode; and displaying operation control means for giving an instruction to said output control means to effect an operation based on said first output mode without effecting a display by said monitor-displaying means, and for giving an instruction to said output control means to effect an operation based on said second output mode so as to output an image signal to produce the above-mentioned second resolution, while effecting a display by said monitor-displaying means.
