Abstract
An image pickup apparatus having a first area-setting circuit for setting, at an arbitrary position in a frame, an area for performing a predetermined image signal process, a second area-setting circuit for fixing the area at a predetermined position in the frame, and a control circuit arranged in such a manner that if an area setting operation of the first area-setting circuit makes an error, then the second area-setting circuit is operated.
Claims25
An image pickup apparatus comprising:
- monitor means for displaying an image signal obtained by image pickup means;
- position appointing means for appointing an arbitrary position on a display frame of said monitor means;
- detection means for detecting an error in appointment made by said position appointing means;
- image-signal fetching control means connected to receive position signals from said position appointing means and to extract an image signal in a region including the position appointed by said position appointing means, said image-signal fetching control means also being connected to receive error signals from said detection means and, in response to error signals being continued for a predetermined time duration, to extract the image signal in a predetermined fixed region in the display means regardless of the position appointed by said position appointing means;
- and
- adjustment means for adjusting image pickup conditions of said image pickup means in accordance with the image signal fetched by said image signal fetching control means.

An image processing apparatus comprising:
- detection means for detecting a visual line of an operator in a display frame;
- region setting means for setting a region, in which a signal is processed, at a position of the visual line in said display frame detected by said detection means;
- and
- control means connected to receive error signals from said detecting means, said control means being responsive to error occurring durations exceeding a predetermined time period to fix the region in which the signal is processed, at a predetermined position in said frame regardless of the position set by said region setting means, said control means further being responsive to error signals which do not exceed said predetermined time period to fix the region at a position immediately before the error has occurred instead of at the position set by said region setting means.

An image processing apparatus comprising:
- gate means for extracting an image signal corresponding to the inside of a predetermined region in a frame;
- appointing means for inputtting position setting information for appointing a set position of said predetermined region in said frame;
- position setting means that controls said gate means in accordance with an output from said appointing means to control the position of said predetermined region in said frame;
- and
- control means connected to receive signals indicating the occurrence of an error in the setting of the position of said predetermined region by said appointing means and, in response to an error occurring state continuing for less than a predetermined time, to maintain said predetermined region at a position immediately before said error occurs regardless of the set position appointed by said appointing means, said control means further being responsive to an error which continues for a time greater than said predetermined time to set said predetermined region at a predetermined fixed position regardless of the position appointed by said appointing means.

An image processing apparatus comprising:
- gate means for extracting an image signal corresponding to the inside of a predetermined region in a frame;
- appointing means for inputting set position information for appointing a set position of said predetermined region in said frame;
- position setting means that controls said appointing means to control the position of said predetermined region in said frame;
- and
- region control means connected to respond to errors in the operation of setting the position inputted by said appointing means and, in response to error occurring states continuing for greater than a predetermined period, to forcibly move said predetermined region to a predetermined fixed position in said frame regardless of the position input by said appointing means, said region control means also being responsive to error occurring states continuing for less than said predetermined period to keep said predetermined region at a position immediately before the error occurs regardless of at the position input by said appointing means.

An image-signal processing apparatus comprising:
- gate means for extracting an image signal corresponding to the inside of a predetermined region in a frame;
- appointing means for inputting set position information for appointing a set position of said predetermined region in said frame;
- position setting means that controls said gate means in accordance with an output from said appointing means to control the position of said predetermined region in said frame;
- and
- position determining means connected to respond to errors which occur in the operation of setting the position of said predetermined region inputted by said appointing means and, in response to error occurring durations within a predetermined time period, to maintain said predetermined region in the position in which it is located immediately before said error occurred regardless of the position input by said appointing means, said position detecting means further being responsive to error occurring states continuing beyond said predetermined time period to forcibly move said predetermined region to a predetermined position in said rame regardless of the position input by said appointing means.
