Embodiment 1

[0039] In order to detect whether the exposure time configured for the photosensitive module takes effect, as shown in Figure 2, a detection module is added to the imaging device in this embodiment, and the imaging device in this embodiment includes a photosensitive module, a gain module, A control module and a detection module, wherein:

[0040] The control module is used to obtain a set of exposure time parameters and gain parameters currently required by calculation and analysis, and output the exposure time parameters to the photosensitive module, and output the gain parameters to the gain module;

[0041] The photosensitive module is used to configure the exposure time according to the received exposure time parameter, and perform photosensitive processing according to the configured exposure time, and output the image obtained by photosensitive to the detection module;

[0042] It often takes a certain time delay for the photosensitive module to receive the exposure time...

Embodiment 2

[0069] In the first embodiment, the detection module outputs an image to the gain module. And because the processing time required by the detection module can be very short, therefore, in this embodiment, as shown in Figure 5, the photosensitive module can directly output the image to the gain module, and the gain module can delay the gain processing of the image to wait Detect module notifications.

[0070] In this embodiment, the control module is used to obtain a set of exposure time parameters and gain parameters currently required through calculation and analysis, and output the exposure time parameters to the photosensitive module, and output the gain parameters to the gain module;

[0071] The photosensitive module configures the exposure time according to the exposure time parameter, and outputs the image obtained by photosensitive to the detection module and the gain module respectively;

[0072] When the detection module detects that the exposure time parameter take...

Abstract

This invention relates to image process field and to one image process method and camera device to ensure visual flow and exposure time parameters and gains parameters, wherein, it analyzes to get one set of matched exposure time parameters and gains parameters and judges exposure time parameter efficiency; if yes, using the matched gains parameters to process the sensor gains; if not using original gains parameters for gain process.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and an imaging device. Background technique [0002] The current imaging equipment is generally shown in Figure 1, including a photosensitive module, a gain module and a control module, wherein the photosensitive module is used to receive light and output the image obtained by photosensitive, in the photosensitive module, there is a register for configuring the exposure time parameter , by adjusting the exposure time parameter, the exposure time when the photosensitive module receives light can be adjusted, so that the brightness of the image output by the photosensitive module changes. For example, when the light is relatively dark, by configuring the exposure time parameter of the photosensitive module to a longer time, the brightness of the image output by the photosensitive module can be made more appropriate. After the exposure time paramet...
