New Canon sensor offers ‘highest’ resolution
Dubai, August 30, 2010
Canon, a global leader in imaging products, said it has recently developed a CMOS image sensor that delivers an image resolution of 120 megapixels, the world’s highest resolution for its size.
Compared with Canon’s highest-resolution commercial CMOS (complementary metal oxide semiconductor) sensor of the same size, comprising approximately 16.1 million pixels, the newly developed APS-H 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, a company statement said.
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 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, according to the statement.
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, the statement said. – TradeArabia News Service
