Canon Umumkan Sensor APS-H 250 Megapixel

Megapixel War is here! Canon baru sahaja umumkan sensor bersaiz APS-H (1.3x crop factor) dengan kemampuan menangkap gambar resolusi 250 megapixel. Buat masa ni inilah rekod sensor bukan full frame resolusi paling tinggi di dunia. Kegunaan utama sensor ini mungkin nak digunakan untuk Aerial Photography, untuk tangkap gambar dengan sangat banyak details. Bila megapixel banyak sangat camni, masalah biasa ialah sensor read out kena cepat sebab banyak data yang dihasilkan. High ISO dan dynamic range macam mana pulak agak-agak? haha.

Berikut adalah official press statement dari Canon.

TOKYO, September 7, 2015
Canon Inc. announced today that it has developed an APS-H-size (approx. 29.2 x 20.2 mm) CMOS sensor incorporating approximately 250 million pixels (19,580 x 12,600 pixels), the world’s highest number of pixels1 for a CMOS sensor smaller than the size of a 35 mm full-frame sensor.

When installed in a camera, the newly developed sensor was able to capture images enabling the distinguishing of lettering on the side of an airplane flying at a distance of approximately 18 km from the shooting location.2

With CMOS sensors, increases in pixel counts result in increased signal volume, which can cause such problems as signal delays and slight discrepancies in timing. The new Canon-developed CMOS sensor, however, despite its exceptionally high pixel count, achieves an ultra-high signal readout speed of 1.25 billion pixels per second, made possible through such advancements as circuit miniaturization and enhanced signal-processing technology. Accordingly, the sensor enables the capture of ultra-high-pixel-count video at a speed of five frames per second. Additionally, despite the exceptionally high pixel count, Canon applied its sensor technologies cultivated over many years to realize an architecture adapted for miniaturized pixels that delivers high-sensitivity, low-noise imaging performance.

Video footage captured by the camera outfitted with the approximately 250-megapixel CMOS sensor achieved a level of resolution that was approximately 125 times that of Full HD (1,920 x 1,080 pixels) video and approximately 30 times that of 4K (3,840 x 2,160 pixels) video. The exceptionally high definition made possible by the sensor lets users crop and magnify video images without sacrificing image resolution and clarity.

Canon is considering the application of this technology in specialized surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and the field of visual expression.

Apa kata anda kat sensor ni? Nak tak kalau Canon jual sensor ni dalam body 1D series? Series tu biasanya yang pakai APS-H ni.
