There is no need to report an error in the log, you are already returning that error to userspace after all. Signed-off-by:

The driver uses the ctrl value passed in as a bool to determine whether to enable auto-exposure, but the auto-exposure setting is defined as an enum where AUTO has a value of 0 and MANUAL has a value of 1. This leads to a reversed logic where if you send in AUTO, it actually sets manual exposure and vice-versa. Signed-off-by:

Add four new controls to configure black level compensation (BLC): - V4L2_CID_BLC_AUTO selects between manual and auto BLC - V4L2_CID_BLC_TARGET_LEVEL sets the target level for auto BLC - V4L2_CID_BLC_ANALOG_OFFSET sets the analog offset for manual BLC - V4L2_CID_BLC_DIGITAL_OFFSET sets the digital offset for manual BLC Signed-off-by:

af9033: implement read_ber and read_ucblocks functions. Version 2 of patch that reflects my findings on the behaviour of abort_cnt, err_cnt and bit_cnt: - bit_cnt is always 0x2710 (10000) - abort_cnt is between 0 and 0x2710 - err_cnt is between 0 and 640000 (= 0x2710 * 8 * 8) in the current implementation BER is calculated as the number of bit errors per processed bits, ignoring those bits that are already discarded and counted in abort_cnt, i.e. UCBLOCKS.

Enabling vflip leads to a much better image, with vflip disabled the image looks washed out as if there is a too high brightness setting. Since we don't know how to lower the brightness setting when not vflipping, simply always vflip and tell userspace to flip the image back, resulting in a much better (less washed out) image. Since the image is now no longer too bright, also modify the luminance level the auto-gain algorithm aims for. Signed-off-by:

Our init sequence was not setting the register page to point to bank 1 before setting what should be the control reg. This causes the camera to sometimes have its LED on after init. First selecting register bank 1, rather then assuming the current register bank is bank 1, fixes this. Signed-off-by:

The pac207's exposure control is a clock-divider, so it goes with quite big steps. So lets use an autogain algorithm optimised for that. Signed-off-by:

We intend to eventually port all sub-drivers to the control-framework. At which point it will make more sense to have the ctrl_handler in gspca_dev then to have it in the subdrivers. Lets move it there now, to avoid a lot of work to move it later. Signed-off-by:

HdG: 1) Let the gspca-core cleanup the controls on control-init error, like with the other converted sub drivers 2) Note this also fixes a bug in the hdcs1020 support which was wrongly reporting an exposure range of 0-65535, even though the effective range was only 0-255 Signed-off-by:

Even with BRC the highest quality setting is not usable, BRC strips so much data from each MCU that the quality becomes worse then using a lower quality setting to begin with. Signed-off-by:
-
Hans de Goede authored
Always automatically adjust the Bit Rate Control setting as needed, independent of the sensor type. BRC is needed to not run out of bandwidth with higher quality settings independent of the sensor. Also only automatically adjust BRC, and don't adjust the JPEG quality control automatically, as that is not needed and leads to ugly flashes when it is changed. Note that before this patch-set the quality was never changed either due to the bugs in the quality handling fixed in previous patches in this set. Signed-off-by:

Hans de Goede authored
The current code is using bits 0-1 of register 8 of the zc3xx controller to set the JPEG quality, but the correct bits are bits 1-2. Bit 0 selects between truncation or rounding in the quantization phase of the compression, since rounding generally gives better results it should thus always be 1. This patch also corrects the quality percentages which belong to the 4 different settings. Last this patch removes the different reg 8 defaults depending on the sensor type. Some of them where going for a default quality setting of 50%, which generally is not necessary in any way and results in poor image quality. 75% is a good default to use for all scenarios.
