Canon, sensore APS-H da 120MPixel
Il nuovo 120 mega pixel Canon
Se i 18 megapixel della 7D oppure gli oltre 21 della 5DMkII vi sembrano pochi, probabilmente il nuovo sensore APS-H (29.2×20.2 mm) da 120MPixel (avete letto bene, tranquilli) appena presentato da Canon potrebbe fare al caso vostro, anche se forse si tratta di un’operazione di marketing piuttosto che dell’annuncio di una nuova fotocamera (analogo annuncio venne effettuato nel 2007 in occasione di un APS-H da 50MPixel, sempre Canon).
Ciò nonostante, le prestazioni sono impressionanti: oltre infatti ad avere la capacità di registrare video FullHD, il nuovo imager è in grado di catturare immagini con una velocità di ben 9,5 frame per secondo… a 120MPixel. Non voglio immaginare la quantità di dati da spostare ogni volta! Servirebbero un paio di queste installate on board per s(o)upportare decentemente un tale carico di lavoro: SanDisk iSSD 64GB. Quindi se ne riparlerà magari tra un paio di generazioni.
Press Release (lingua inglese)
TOKYO, August 24, 2010—Canon Inc. announced today that it has successfully developed anAPS-H-size*1 CMOS image sensor that delivers an image resolution of approximately 120 megapixels (13,280 x 9,184 pixels), the world’s highest level*2 of resolution for its size.
Compared with Canon’s highest-resolution commercial CMOS sensor of the same size, comprising approximately 16.1 million pixels, the newly developed sensor features a pixel count that, at approximately 120 million pixels, is nearly 7.5 times larger and offers a 2.4-fold improvement in resolution.*3
With CMOS sensors, while high-speed readout for high pixel counts is achieved through parallel processing, an increase in parallel-processing signal counts can result in such problems as signal delays and minor deviations in timing. By modifying the method employed to control the readout circuit timing, Canon successfully achieved the high-speed readout of sensor signals. As a result, the new CMOS sensor makes possible a maximum output speed of approximately 9.5 frames per second, supporting the continuous shooting of ultra-high-resolution images.
Canon’s newly developed CMOS sensor also incorporates a Full HD (1,920 x 1,080 pixels) video output capability. The sensor can output Full HD video from any approximately one-sixtieth-sized section of its total surface area.
Images captured with Canon’s newly developed approximately 120-megapixel CMOS image sensor, even when cropped or digitally magnified, maintain higher levels of definition and clarity than ever before. Additionally, the sensor enables image confirmation across a wide image area, with Full HD video viewing of a select portion of the overall frame.
Through the further development of CMOS image sensors, Canon will break new ground in the world of image expression, targeting new still images that largely surpass those made possible with film, and video movies that capitalize on the unique merits of SLR cameras, namely their high mobility and the expressive power offered through interchangeable lenses.
- The imaging area of the newly developed sensor measures approx. 29.2 x 20.2 mm.
- As of August 20, 2010. Based on a Canon study.
- Canon’s highest-resolution commercial CMOS sensor, employed in the company’s EOS-1Ds Mark III and EOS 5D Mark II digital SLR cameras, is equivalent to the full-frame size of the 35 mm film format and incorporates approximately 21.1 million pixels. In 2007, the company successfully developed an APS-H-size sensor with approximately 50 million pixels.
un paio di generazioni????? io direi che siamo pronti ad una seconda puntata della rivoluzione…la RED di canon sta per arrivare
La 4K a forma di asciugacapelli presentata al CanonExpo? Dovrebbe essere interessante, sicuro. Io mi riferivo al fatto che per fotocamere con sensore da 120MPixel ci vorrà ancora un po’ perché la quantità di dati da scaricare è tale per cui i costi, attualmente, sarebbero improponibili.
