The highest-value accuracy change
Good capture, narrow crops, and deliberate verification beat cosmetic image filters.
A capture checklist before upload
Start with
The original camera photo, before filters or repeated file exports.
Why it helps
A square, close, evenly lit image gives OCR clearer character shapes.
Inspect first
Check the smallest important word at full size before you upload.
Capture text, not the whole scene
Move close enough that small characters have clear edges, but keep the full line or label in frame. Crop unrelated objects. Hold the camera parallel to the page so the top and bottom lines have similar width.
Diffuse light is better than a bright reflection. If a laminated menu or screen has glare, change the camera angle slightly while keeping the text square. Tap the text area to focus and pause before taking the photo.
Prepare difficult sources
Rotate the image upright before uploading. For a long menu, use several overlapping photos instead of one distant image. For tiny packaging text, photograph one panel at a time. Screenshots should be uploaded directly rather than photographed from another screen.
Do not sharpen aggressively. Oversharpening can create false strokes around characters. Moderate contrast and a clean crop are safer than filters that make a photo look dramatic.
Before uploading, the OCR image readiness checker can expose dimensions, blur, and contrast issues in the browser.
Verify the parts that matter
Compare every number, unit, date, name, address, warning, and negative phrase with the original. Read the extracted text before the translation. If the OCR text is wrong, take a better photo or correct the source text before relying on the translated version.
When two meanings are plausible, preserve the ambiguity. Context such as the page title, nearby icon, product type, or previous sentence may resolve it. The translation should not invent certainty the photo does not contain.
