Samsung proclaims 200MP ISOCELL HP3 picture sensor with trade’s smallest pixels: Digital Pictures Overview


Samsung has introduced a brand new 200MP picture sensor, the ISOCELL HP3. The cell imaging sensor options the trade’s smallest pixels, at 0.56-micrometer (μm), lowering the general picture sensor and digital camera module dimension.

‘Samsung has constantly led the picture sensor market development by way of its know-how management in excessive decision sensors with the smallest pixels,’ mentioned JoonSeo Yim, Government Vice President of Sensor Enterprise Workforce at Samsung Electronics. ‘With our newest and upgraded 0.56μm 200MP ISOCELL HP3, Samsung will push on to ship epic resolutions past skilled ranges for smartphone digital camera customers.’

The ISOCELL HP3 is not Samsung’s first 200MP picture sensor. The corporate introduced the ISOCELL HP1 final fall, and we not too long ago noticed some real-world photographs captured with that 200MP sensor. The ISOCELL HP3 options 12 p.c smaller pixel dimension than the HP1 in a 1/1.4″-type format (11.5mm diagonal, giving a 3.78x crop issue).

Samsung states the discount in pixel dimension ends in an roughly 20 p.c discount in digital camera module floor space in comparison with the HP1, permitting smartphone producers to make smaller, thinner smartphones.

The ISOCELL HP3 consists of Tremendous Quad Section Detection (QPD) autofocus know-how, that means all of the sensor’s pixels contribute in the direction of its autofocus capabilities. Tremendous QPD is comparable with Sony Semiconductor’s ‘Quad Pixel AF‘ system, utilizing a single lens over 4 adjoining pixels, permitting the sensor to detect section variations in horizontal and vertical instructions (cross-type). Samsung guarantees’ extra correct and faster’ autofocus efficiency for smartphone digital camera customers.

As for video, the HP3 information 8K decision video at as much as 30 frames per second and 4K video at as much as 120 frames per second. There’s ‘minimal loss’ within the area of view when recording 8K footage, but it surely’s unclear what exact crop issue will happen.

Just like the ISOCELL HP1, the HP3 has an over-sized Bayer sample, with every colour extending throughout 4×4 squares of photosites. That is an extension of the corporate’s 2×2 ‘Tetracell’ (c.f Quad Bayer) know-how, and is now branded Tetra2.

This enables the digital camera to mix teams of 16 photosites to ship 12.5MP photographs with successfully 2.24μm pixels. It is also doable for processing to attempt to reconstruct the a standard Bayer association would have produced for its 50MP and 200MP photographs (a course of Samsung calls ‘re-mosaicing’). This means to mix pixels delivers improved efficiency in low gentle, however means the total res photographs will not be as detailed a 200MP Bayer sensor would.

The sensor additionally consists of what it calls a ‘Good-ISO Professional’ characteristic. This exploits the outsized Bayer sample by capturing completely different rows of pixels with completely different quantities of acquire to seize extra dynamic vary. In earlier cases, Samsung talked about utilizing completely different ranges of ‘conversion acquire’ (ie: the 2 in-pixel readout modes). As a substitute with the HP3 Samsung talks about combining ‘ISO’ ranges, quite than acquire ranges. It says the brand new chip can mix a ‘low ISO mode’ with both a mid or a excessive ISO mode, to seize much more dynamic vary. This means Samsung is utilizing an amplifier, quite than simply the sensor’s two conversion acquire modes.

This new method and the broader dynamic vary it captures has prompted a transfer from combining the info in 12-bit information to 14-bit as an alternative, offering room for this extra dynamic vary.

Because the Good-ISO Professional HDR mode is presumably delivered at a decrease decision, the chip additionally provides a staggered HDR mode, taking pictures three images with completely different exposures, one after the opposite (with a danger of topic motion between frames). Each the staggered and Good-ISO Professional HDR modes are additionally provided in video mode. The HP3 can shoot at as much as 8K/30 or ship its HDR seize in 4K and FullHD.

Samsung already has accessible samples of the ISOCELL HP3 sensor and expects mass manufacturing to start this 12 months. It is unclear when customers ought to count on the primary smartphones geared up with the ISOCELL HP3 to ship.
