Image Sensor with Sensitivity Control and Sensitivity based Wide Dynamic Range

An image sensing device, comprising:

• an image sensor comprising an array of pixel elements, the array comprising at least two regions of pixels elements, each region comprising one or more pixel elements, the image sensor being configured to generate output signals at each pixel element as pixel data representing an image of a scene, the image sensor implementing one or more control parameters, each control parameter modifying the sensitivity of the pixel elements in the array;
• and
• a control circuit configured to generate one or more control signals, each control signal for varying a control parameter for a given region of pixel elements of the array, the one or more control signals being generated to vary the sensitivity of the pixels elements on a region by region basis within the array in accordance with the scene.

An image sensing device, comprising:

• an image sensor comprising an array of pixel elements, the image sensor being configured to generate output signals at each pixel element as pixel data representing an image of a scene, the pixel data of all pixel elements collectively representing the image of the scene, the image sensor implementing a plurality of control parameters, each control parameter modifying the sensitivity of the pixel elements in the array;
• and
• a control circuit configured to generate a plurality of control signals, each control signal for controlling a control parameter for the entire array of pixel elements, the plurality of control signals being generated to vary the sensitivity of the pixels elements to provide continuous fine grain control of the sensitivity of the pixel elements in accordance with the scene.
