8.5.9 Configure the VIQS setting
Click the [Setup>>] button of “VIQS” on the [Image/Position] tab of the “Image/Audio” page. (→8.5 Configure the settings relating to image position [Image/Position])
VIQS is an abbreviation of Variable Image Quality on Specified area and is a feature that enables you to change the images of a specified area.
It is possible to enhance the image quality of the specified range within a shooting area (image).
It is also possible to moderate the image data size by lowering the image quality of other areas.
The VIQS setting is available only for H.264 images.
VIQS can be set to preset position numbers 1 to 8 as well as settings other than preset positions, and up to 8 VIQS areas can be set for each preset position.
To check the image after configuring VIQS, when H.264 images are selected under “Stream”, you can check the image by pressing the [Confirm] button. You can also check by displaying an H.264 image on the “Live” page.
