Estimating the term…
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.
A device comprising:
A computer-readable medium storing a set of instructions, wherein the set of instructions when executed by one or more processors comprises:
A device that performs image processing comprising a hand jitter reduction mode having a means for detecting a light level and means responsive to the detected light level for reducing hand jitter, the reducing of the hand jitter including single frame noise reduction when the light level is in a first range and multiple frame noise reduction when the light level is in a second range.
An integrated circuit adapted to be coupled to an image sensor responsive to modified auto-exposure parameters generated by the integrated circuit to reduce hand jitter of captured digital images in hand jitter reduction mode, comprising:
A method of generating modified auto-exposure parameters comprising:
