The invention relates to methods for operating a camera device (4) for a motor vehicle (3). An image sensor (5) of the camera device (4) provides a raw image (R) of an environment (8) of the camera device (4). An image processing device (6) generates an output image (I) from the raw image (R) by means of a spreading function (13) of a histogram spreading (12). The spreading function (13) generates from a respective input pixel value (Li) of each pixel of the raw image (R) each one output pixel value (Lo) of a corresponding pixel of the output image (I). It is the object of the invention to adapt the histogram spreading (12) to the capturing situation. At least one parameter value (S, G) of the camera device (4) depending on a brightness (B1, B2) of the environment (8) is acquired and a limit value (L) for the output pixel values (Lo) is set in the spreading function (13) depending on the at least one acquired parameter value (S, G).

An imaging apparatus includes a photographic lens, an imager, a diaphragm, a drive unit, and a control unit. The imager receives light fluxes passing through the photographic lens to generate an imaging signal. The diaphragm regulates the light fluxes passing through the photographic lens and received by the imager. The drive unit drives the diaphragm. The control unit performs still image continuous photography and displays a live-view image on a display unit during each main exposure of the still image continuous photography. The control unit controls a start timing of the driving of the diaphragm for the main exposure performed by the drive unit while the live-view image is displayed during each main exposure of the still image continuous photography, in accordance with a drive speed of the diaphragm.

An apparatus obtains a captured image, obtains exposure setting relating to the captured image, obtains for luminance of a scene, sets a mode for generating the display image; and generates the display image by performing luminance conversion of the captured image depending on the set mode. The apparatus performs, in a case where a first mode is set, the luminance conversion of the captured image using a first conversion characteristic indicating that output luminance after conversion is determined for the luminance of the scene, and does not change depending on the exposure setting. And the apparatus performs, in a case where a second mode is set, the luminance conversion of the captured image using a second conversion characteristic indicating that the output luminance changes depending on the exposure setting.
