- Image rotation function
The image rotation method depend on the screen rotation setting for the OS.
Refer to the section on ”Camera Rotation” in the MSDN Library for the image rotation
specification.
Item Image Setting parameters
Preview display (Rotates in the clockwise direction)
No rotation (normal)
90° (when the OS specifies image rotation 90° to the
right)
270° (when the OS specifies image rotation 90° to
the left)
Image rotation
Captured image (Rotates in the clockwise direction)
No rotation (normal)
90° (when the OS specifies image rotation 90° to the
right)
270° (when the OS specifies image rotation 90° to
the left)
- Frame rate adjustment
The frame rate output from the camera module to the preview screen is automatically adjusted
according to the brightness of the surroundings, within a range so that the maximum frame rate is
not exceeded. The CMOS camera module has a function to set this maximum frame rate.
The maximum frame rate setting function is a function to set the maximum frame rate value output
from the camera during preview display. The maximum frame rate value can be switched to one of
four levels. When shooting video, the software resources used for encoding are greatly influenced
by this maximum frame rate value. The more the maximum frame rate is increased, the longer the
encoding time gets, and the more program memory is used.
Item Setting parameters Remarks
Maximum frame rate = Low Encoding time for video capture =
Short,
Program memory usage = Small
Maximum frame rate =
Standard
Encoding time for video capture =
Medium,
Program memory usage =
Medium
Maximum frame rate = High Encoding time for video capture =
Long,
Program memory usage = Large
Maximum frame rate setting
function
Maximum frame rate =
Maximum
Do not use this for video capture.
