摘要： A method for optimizing a selection of spectral sensitivities for an imaging device includes determining a first set of spectral sensitivities from an initial set of spectral sensitivities based on an analysis of one of a universal measure of goodness, a μ-Factor, and RMS noise. A second set of spectral sensitivities is determined from the first plurality of sets of spectral sensitivities based on an analysis of a different one of the universal measure of goodness, the μ-Factor, and the RMS noise. The second set of spectral sensitivities is an optimized set of spectral sensitivities.

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。
