Professional HD Quality
Progressive 3CCD and 2/3-inch Interchangeable Lens System for Full-Fledged HD Video Production
2/3-Inch Interchangeable Lens System
The 2/3-inch bayonet mount allows use of a wide assortment of broadcast and professional lenses from a number of companies*. 2/3-inch zoom lenses make it easier to capture the shallower depth of field often used in professional videos.
The camera process scans at full 1080/60 (or 50) progressive frames a second. It is this initial capture that is the foundation for all of the formats that this camera generates. While the camera does not record 1080P/60(or 50), the signals start there and are either cross converted or down converted to the format being utilized that day.
* The effective image size of the CCD is equivalent to 2/3.2 inches.
Chromatic Aberration Compensation (CAC)
Chromatic Aberration Compensation (CAC) function is a new feature in the AG-HPX502. This exclusive technology sets up a conversation between lens and camera which allows for a highly sophisticated algorithm to be deployed which will automatically compensate the registration error that is caused mainly by lens chromatic aberration, and minimize the circumjacent blur.

Progressive 3CCD
The AG-HPX502's 2/3-inch progressive 3CCD* has a larger light receiving area for higher sensitivity, and achieves an optimal balance among image quality, sensitivity and cost.

A.P.T for Higher Image Quality
Advanced progressive technology (A.P.T) produces higher total image quality by linking the progressive 3CCD camera system with a high-performance digital signal processor (DSP). In A.P.T, an extremely accurate CCD alignment process is used to offset the pixels on the red and blue channels in both the Horizontal and Vertical directions. This allows for additional resolution to be gained from areas of the green CCD which are non-photo-sensitive.
The R, G and B color signals from the 3 CCDs are then sent through a 14-bit A/D converter. Next, a 19-bit DSP performs a highly precise calculation* on the signals to generate 1080/60P (50P) video signals. The signals are then converted into HD or SD format and recorded. By using these progressive video signals, with their excellent vertical resolution, as source signals, a high level of image quality is achieved that would be difficult to obtain by interpolating from interlace scans.
* Called an advanced offset spatial process.

**“Simulated” images were produced in order to describe the function. It is not a screen capture of an actual image. It differs from an actual image in that the effect of the function has been emphasized for easier understanding.
