Means "immediate" in Japanese. CCD sensor shuttering technology for asynchronous shooting of fast moving objects without a time delay.
Industry:Consumer electronics
Inside a camera, sensor signals must be processed in several steps before they can be displayed / transmitted. Typical processing steps are amplification, gamma correction, black level correction, highlight compression/clipping, edge enhancement, color processing, color balance, color correction, output signal encoding. Picture quality is highly dependent on the accuracy and the stability of these processes. In DSP technology, the sensor signal is converted to digital form after initial amplification, and all processing is achieved digitally, ensuring high quality and no drift. Output signals remain in digital form or are converted back to analog depending on the camera output mode.
Industry:Consumer electronics
A unique feature function available when using Digital Signal Processing (DSP) technology. It manages the contrast of each pixel according to a histogram of video signal level distribution in order to utilize the limited dynamic range of the video signal standard. This function is used in the DXC-390/P camera.
Industry:Consumer electronics
Enhanced asynchronous shutter. Available with external and internal synchronization modes. The camera CCD starts to accumulate electrons on receipt of an external trigger pulse. Shutter speed is selected by a switch or menu setting.
Industry:Consumer electronics
A function of Digital Signal Processing (DSP) technology that virtually eliminates hue factor distortion – phenomenon that is particularly obvious in extreme high light conditions. The DCC+ function manages video signal data at three levels – brightness, hue and saturation that results in reproduced images with suitable knee correction while virtually eliminating hue factor distortion. This function is used in the DXC-390/P camera.
Industry:Consumer electronics
Asynchronous shutter mode. Available in external sync mode only. Timing of accumulation and shutter speed are controlled by the external trigger signal. Shutter speed is controlled by the width of the pulse and VD controls the timing for image output.
Industry:Consumer electronics
B/W video standard with 525 lines / frame, 2 interlaced fields / frame, 30 frames / second. Monochrome version of NTSC video signal. Also referred to as RS-170.
Industry:Consumer electronics
CCD camera operating mode where the integration time can be shortened without any mechanical device. Used for blur reduction when capturing fast moving objects, and for camera sensitivity reduction in high levels of scene illumination.
Industry:Consumer electronics
Technology with a nearly gapless OCL (On-chip-lens) located over each pixel of the CCD resulting in more than twice the sensitivity and 1/50 the smear compared to Hyper HAD technology.
Industry:Consumer electronics
Calibrated measure of lens iris aperture. Common F stops are F1.4, F2, F2.8, F4, F5.6, F8, F11, F16, F22. The higher the number, the smaller the iris aperture and the less light falling on the imager.
