However the file size hardly varies at all, and seems to be constant at around 30 KB. Depending on the scene you are capturing, the quality is constant at 99 but the file size varies accordingly on the 450D it normally varies between 100 KB and 250 KB.Ĭompare this to Nikon and the JPEG compression quality is much lower and varies much more, between 50 to 80. In fact, it may be that JPEG it just used as a convenience for packaging and transferring the image data to the PC. I've cropped them to the same size for comparison (426x426), and intentionally did not adjust for the difference in original size which explains why the 450D scene is larger.Īs shown in the first table, Canon are using JPEG compression with the highest possible quality, and so the final image has very little loss of information. Here are the live view images from the two cameras. In proportion to the image size, the Nikon live view image is compressed 4 times as much as the Canon image, and this has a big impact on the quality of the final image. Just from the file sizes its obvious that Nikon are much more aggressive with their JPEG compression settings. Not just in the width and height of the images, but also in the image quality. That is, adding the ability to view the live view images from multiple camera simultaneously, and even to use a dual camera rig to view a realtime stereo anaglyphic preview.Īn interesting observation will doing this is how much the live view output varies between different cameras. I am able to see photos, the serial number, or take a single pictureĪlso found a NikonHacker website, but the forum broke in early 2020, so you can't create a new account or post anything.One of the features I'm working on for Smart Shooter is improving how live view works. Updated firmware from 1.1 to 1.1 (I don't know, worth a try).Add "Video Capture Device" > Select "Nikon Webcam Utility" from dropdown.I can't figure out how to get it to the live video input. I can interact with the menu and the Up/Down/Left/Right for navigation, but nothing I do takes it out of the Media View section.It shows the 1 photo stored on internal memory.Add "Video Capture Device" > Select "USB Video" from dropdown.Change Win 10 Privacy setting to allow apps to have camera access.Plugged Camera HDMI out cable into HDMI Video Capture device.Plugged Coolpix L830 into DC power (wall).I've been looking around trying to find a way to get the live view to display on my computer, so I can use it as a webcam for streaming.
