Method of photography processing for camera module, terminal, using same and storage medium implementing same

A terminal, comprising a housing, a circuit board, a camera module, and a power supply circuit, wherein the circuit board is disposed in an inner space enclosed by the housing, and the power supply circuit is configured to power each circuit or component of the terminal;

• wherein the camera module comprises an image sensor, the image sensor comprises a photosensitive unit array, a filter unit array arranged on the photosensitive unit array, and a microlens unit array arranged on the filter unit array;
• wherein the photosensitive unit array comprises M pairs of first focusing photosensitive units with center lines parallel to each other and N pairs of second focusing photosensitive units with center lines parallel to each other, a microlens unit covers a filter unit and a pair of focusing photosensitive units;
• wherein an intersection angle between a center line of a pair of first focusing photosensitive units and a center line of a pair of second focusing photosensitive units is greater than 0 degree, and M and N are positive integers greater than or equal to 1;
• and
• wherein density of the focusing photosensitive units arranged on the vertical center line and horizontal center line of the image sensor is greater than that of the focusing photosensitive units arranged on two diagonal lines of the image sensor.

A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the program, when executed by a processor, implements a method of photography processing for a camera module;

• wherein the camera module comprises an image sensor, and the image sensor comprises a photosensitive unit array, a filter unit array arranged on the photosensitive unit array, and a microlens unit array arranged on the filter unit array;
• wherein the photosensitive unit array comprises M pairs of first focusing photosensitive units with center lines parallel to each other and N pairs of second focusing photosensitive units with center lines parallel to each other, a microlens unit covers a filter unit and a pair of focusing photosensitive units;
• wherein an intersection angle between a center line of a pair of first focusing photosensitive units and a center line of a pair of second focusing photosensitive units is greater than 0 degree, and M and N are positive integers greater than or equal to 1;
• wherein the density of the focusing photosensitive units arranged on the vertical center line and horizontal center line of the image sensor is greater than that of the focusing photosensitive units arranged on two diagonal lines of the image sensor;
• and
• wherein the method comprises:
• controlling the photosensitive unit array to enter a focusing mode;
• reading a first set of output values of the M pairs of first focusing photosensitive units;
• reading a second set of output values of the N pairs of second focusing photosensitive units;
• and
• performing focusing control according to the first set of output values and the second set of output values.
