Limits RegistryKodak engineer Steven Sasson built a battery-operated digital camera in 1975 that weighed about 8 lb (3.6 kg) and used a Fairchild CCD sensor of just 100x100 pixels (0.01 megapixels). Each black-and-white image took about 23 seconds to record onto a cassette tape and had to be played back on a modified television set.

Kodak engineer Steven Sasson built a battery-operated digital camera in 1975 that weighed about 8 lb (3.6 kg) and used a Fairchild CCD sensor of just 100x100 pixels (0.01 megapixels).

The earliest year in which a portable, self-contained camera captured an image with a solid-state sensor and stored it digitally.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
