Scouter (Honest) — A-09 · Scouter Honest Amber

View — reticle / HUD

Camera status: not started — nothing is measured until you press START

The amber box drawn inside the view is the brightest region — the grid cell with the highest mean luminance in the current frame. It is labeled as exactly that, and as nothing more: it is not a person, a target in any other sense, or a finding.

Upload a photo instead

Camera runs only behind the START button, only in this tab, and can be stopped. A photo upload works with no camera at all: luminance, contrast, colour and the brightest region are measured from that still; motion and frame rate print UNAVAILABLE for a still, because a single image has neither.

How each number is computed

Mean luminance: per pixel Y = 0.2126·R + 0.7152·G + 0.0722·B (Rec. 709 luma), then the mean of Y over a down-sampled copy of the frame (160 × 120 at most). Scale 0–255.
Contrast: the standard deviation of Y over the same pixels — the luminance spread. 0 means a flat, uniform frame.
Motion index: mean absolute frame-to-frame difference of Y, sampled over the same pixels — mean(|Y_now − Y_prev|), scale 0–255. Large means a lot changed between frames; it does not say what moved.
Dominant color: the mean R, G and B of the frame, shown as that average colour and named by its strongest channel.
Warm/cool estimate: mean R minus mean B. Above +10 prints Warm, below −10 prints Cool, in between prints Balanced. A simple colour-temperature hint from the averages, nothing more.
Measured frame rate: frames actually processed by this page, counted over a rolling 1-second window. Counted, not assumed — it is this page's processing rate, not a camera specification.
Brightest region: the frame is split into an 8 × 6 grid; the cell with the highest mean Y is boxed and reported by grid position.

No face detection runs on this page. No identification of people, ever. No image, frame, or reading leaves this tab, and nothing is stored.
