Overview

Image capture controller have become popular in a wide range of devices, including still cameras, video cameras, automobiles, security and monitoring equipment, computers and so forth. The properties of image sensors, including CCD and CMOS devices, may deviate from idealized values depending on the particular manufacturing process, which in turn may affect final image quality. For this reason, NVM finds use in recording the actual values of a given image sensor, which can then be utilized in trimming the deviation. NVM can also record the location of defective pixels in an image sensor to allow compensation. Properties of analog circuits can be recorded in NVM and trimmed to correct for analog circuit deviations. eMemory provides complete solutions for these NVM applications.

NeoEE Flash HE and NeoFlash Flash HD can be used to record parameter for sensor values of a CCD/CMOS sensor. Storage of trimming and defect compensation settings can be executed at the CP or FT stage by NeoBit OTP HR and NeoBit PMTP HR. The two HR series can also record values for circuit properties and the panel response time for trimming purposes. The properties include: overdrive (in a look-up table), ADC, DAC, PLL, regulator, current, and voltage. Values for these properties can be calibrated at the FT or system integration stage.
