Στην ψηφιακή φωτογραφία, η ποιότητα εικόνας εξαρτάται από τρείς σημαντικούς παράγοντες: τον φακό, τον αισθητήρα εικόνας, και την ταχύτητα επεξεργασίας. Με φωτεινούς φακούς, υψηλής ποιότητας αισθητήρα και γρήγορη ταχύτητα επεξεργασίας, η Olympus αναβαθμίστηκε ακόμη περισσότερο. Με τα ενσωματωμένα συστήματα σταθεροποίησης εικόνας (IS), μπορείτε να ξεγελάσετε ακόμα και τη φυσική.
Image blur has ruined uncountable numbers of shots, and millions of times photographers have been angry about opportunities they thought they’d taken but in the end have lost. One of the causes of image blur is camera shake. The hand that holds the camera always shakes a little, althought he photographer hardly ever otices this, and under normal conditions it rarely becomes apparent in the pictures taken. Especially when stooting with high focal lengths or slow shutter speeds, even slight movements of the camera result in blurred images. So that you don’t need to carry a heavy tripod or invest extra money into every single stabilised lens, Olympus integrated a built-in image stabiliser into the camera body of the E-3 and E-510. It stabilises up to 5 EV steps (up to 4 EV steps with the E-510), making it the most effective solution on the market. Click here to read more
The Live MOS sensors of the E-3, the Ε-420, E-410, E-510 and already in the E-330 offer fantastic image quality with the low power requirements of a CMOS sensor, and is noteworthy for its high-quality imaging capabilities over an extended period of time. Simplified circuitry that reduces the distance from each photodiode to its corresponding on-chip microlens assures excellent sensitivity and image quality even when light strikes it at a high angle of incidence. A new transfer mechanism for photodiode signal readout enabled us to reduce the number of circuit paths to two and thereby minimize the surface area that is unresponsive to light. By effectively enlarging the photosensitive surface area and enabling it to capture light that was previously lost, we were able to achieve both high sensitivity and superior image quality. We also developed a new low-noise photodiode signal amplification circuit to further improve sensitivity.
For the E-400, the whole concept of an interline CCD was reviewed and thereby drastically improved. The CCD has been restructured to shorten the transfer gate and bring the transfer circuity and photodiode closer and to achieve the objective of increasing the accumulated charge by decreasing the loss of handled signals. This has resulted in the ideal interline CCD, one that provides both high image quality (thanks to the large accumulated charge capacity) and low noise (thanks to high efficiency of converting charge to voltage). The excellent low-noise characteristics of the CCD are supported by a newly adopted noise filter and IR-cut filter that maximise the image quality of the enlarged image captured with 10 megapixels.
The Olympus E-500 features a Four Thirds type Full Frame Transfer CCD. It has been specially designed for high-performance digital still image capture. Full Frame Transfer sensor enables images of stunning quality to be produced. The CCD integrated in the Olympus E-500 has a considerably higher photodiode aperture ratio (fill factor) and provides a larger transferable signal. One of the reasons is that pixels are comprised of a photo diode, where the signals are generated, as well as a so called transfer channel, which is used to transport the signals to the processors.

The image processing engine comprises a combination of hardware (processors) and software (algorithms). Among its tasks, it gathers information about the luminance and chrominance from the individual pixels and uses it to compute the correct colour and brightness values for each pixel. This results in images with natural and pleasing colours, balanced contrast and sharpness. With Olympus E-System cameras, you receive natural skin colours and a realistic blue colour of the sky. Also you don’t want your images to show noise, a negative side effect also in digital photography. A good image processor separates the noise from the image information and removes it.
With the TruePic III engine, Olympus created a masterpiece to ensure image depth, clarity and fine details. Colours come out warm and natural with Advanced Proper Gamma III technology, the Advanced Noise Filter III contributes to the faithful reproduction of images through the reduction of noise by isolating the image and noise signals accurately. And the Advanced Detail Reproduction technology cares for smooth and sharp edges by accurately detecting directions. Applying a Low Pass Filter in the edge direction and a High Pass Filter in the edges normal line direction, edges become smooh and false colours can be completely eliminated. You won’t find any fuzzy lines on your images any more!
Όλοι οι φακοί ZUIKO DIGITAL, συμβατοί με το πρότυπο Τεσσάρων Τρίτων της Olympus, είναι ειδικά σχεδιασμένοι για την ψηφιακή φωτογραφία.
Η εξαιρετικά υψηλή τους ανάλυση, που έρχεται σαν αποτέλεσμα της μακράς και πολύπλοκης διαδικασίας κατασκευής, εκμεταλλεύεται πλήρως τις επιδόσεις του αισθητήρα εικόνας.
Μόνο όταν σε κάθε Pixel χωριστά αποδίδεται ακριβής και ξεχωριστή οπτική πληροφορία από το φακό, γίνεται εφικτή η μέγιστη ανάλυση με λεπτομερή αναπαραγωγή της εικόνας. Οι περισσότεροι φακοί για μηχανές 35mm δεν έχουν την ικανότητα να διαχωρίζουν τις μικρότερες λεπτομέρειες στη διάμετρο του κάθε pixel του αισθητήρα λήψης, ειδικά στις γωνίες, και γι' αυτό δεν μπορούν να παράσχουν σε αυτόν την απαιτούμενη ακριβή πληροφορία. Ένας φακός που έχει αναπτυχθεί για χρήση σε ψηφιακή απεικόνιση έχει σημαντικά αυξημένη αναλυτική ικανότητα, μικρότερη από τη διάμετρο του pixel. Με αυτό τον τρόπο οι μικρότερες λεπτομέρειες δεν αλληλοκαλύπτονται μεταξύ γειτονικών pixel.
Επιπρόσθετα, το σύστημα επικοινωνίας μεταξύ φακών και σώματος μηχανής μεγιστοποιεί τον έλεγχο της λήψης της εικόνας.
