HM0445中文资料Automotive VGA数据手册Himax规格书

描述 Description

The HM0445 is an automotive VGA image sensor SOC that delivers excellent low light sensitivity and noise performance in a compact 30mm2 chip scale package. The sensor provides 640 x 480 active pixels that can be panned across an additional 80 horizontal pixels and 60 vertical pixels to compensate for camera lens alignment tolerance.

The HM0445 features Himax Imaging’s ClearViewTM ISP that enhances the sharpness and clarity of the image based on the optical properties of the lens. The on-chip automatic exposure, gain, white balance and ISP parameters quickly adapts the sensor across a broad range of lighting conditions.

The HM0445 supports multiple sensor initialization options using internal OTP or external SPI memory. The sensor offers a high level of integration including voltage regulators, temperature sensor, crystal oscillator, fast locking clock generator, and analog video encoder with current driver. The HM0445 enables the design of compact full-featured camera system for a wide variety of automotive camera applications.
