Abstract
A camera device is provided that has an image sensor having a plurality of pixel elements for recording image data of an object stream of objects moving in a direction of movement relative to the camera device and a control and evaluation unit that is configured to read and further process the image data from the image sensor, wherein the image sensor is configured as a high frequency binary image sensor that generates individual images of low bit depth at a high frame rate, In this respect, the control and evaluation unit is configured to trigger a plurality of repeated shots of individual images of the image sensor and to combine the individual images while compensating the movement of the object stream between the shots to form a common image.

A camera device that has an image sensor having a plurality of pixel elements for recording image data of an object stream of objects moving in a direction of movement relative to the camera device and a control and evaluation unit that is configured to read and further process the image data from the image sensor, wherein the image sensor is configured as a high frequency binary image sensor that generates individual images of low bit depth at a high frame rate,
- wherein the control and evaluation unit is configured to trigger a plurality of repeated shots of individual images of the image sensor and to combine the individual images while compensating the movement of the object stream between the shots to form a common image, and
- wherein the speed of the objects is predefined for the control and evaluation unit.
A camera device that has an image sensor having a plurality of pixel elements for recording image data of an object stream of objects moving in a direction of movement relative to the camera device and a control and evaluation unit that is configured to read and further process the image data from the image sensor, wherein the image sensor is configured as a high frequency binary image sensor that generates individual images of low bit depth at a high frame rate,
- wherein the control and evaluation unit is configured to trigger a plurality of repeated shots of individual images of the image sensor and to combine the individual images while compensating the movement of the object stream between the shots to form a common image, and
- wherein the control and evaluation unit is configured to adapt the compensation of the movement to compensate lens defects and/or projective distortion to the respective position within the individual images.
A method of detecting objects of an object stream moving in a direction of movement in which image data of the object stream are recorded and evaluated by an image sensor with a plurality of pixel elements, wherein the image sensor is configured as a high frequency binary image sensor that generates individual images of low bit depth at a high frame rate,
- wherein a plurality of repeated shots of individual images of the image sensor are generated and the individual images are combined while compensating the movement of the object stream between the shots to form a common image, and
- wherein the speed of the objects is predefined for the control and evaluation unit.
