摘要： This disclosure describes an efficient architecture for an imaging device that supports image registration for still images and video coding of a video sequence. For image registration, the described architecture uses block-based comparisons of image blocks of a captured image relative to blocks of another reference image to support image registration on a block-by-block basis. For video coding, the described architecture uses block-based comparisons, e.g., to support for motion estimation and motion compensation. According to this disclosure, a common block comparison engine is used on a shared basis for both block-based image registration and block-based video coding. In this way, a hardware unit designed for block-based comparisons may be implemented so as to work in both the image registration process for still images and the video coding process for coding a video sequence.

摘要： A camera system in normal mode and hand jitter reduction (hjr) mode may comprise generating a first exposure time-gain product by multiplying the normal mode exposure time with the normal mode gain. It may further comprise modifying the normal mode exposure time and gain and multiplying these modified parameters to generate a second exposure time-gain product for a hjr mode that reduces the difference between the first exposure time-gain product and the second exposure time-gain product. To reduce the difference the normal mode frame rate may also be modified. Operation of a camera in normal mode may be in response to a sensed light level being above a threshold. The hjr mode may be selected by the user while the camera is operating. The hjr mode may be used in response to a sensed light level being lower than the threshold.
摘要翻译：正常模式和手抖动降低（hjr）模式的相机系统可以包括通过将正常模式曝光时间与正常模式增益相乘来产生第一曝光时间增益积。它还可以包括修改正常模式曝光时间并增益并且乘以这些修改的参数以产生用于hjr模式的第二曝光时间增益乘积，其减小第一曝光时间增益乘积与第二曝光时间增益乘积之间的差。为了减小差异，也可以修改正常模式帧速率。在正常模式下照相机的操作可以响应于感测到的光电平高于阈值。当相机运行时，用户可以选择hjr模式。响应于感测到的光水平低于阈值，可以使用hjr模式。
