Claim 17:
18. A method comprising:
operating each pixel cell of at least a subset of an array of pixel cells to generate charge in response to light, and to convert the charge to output a voltage;
in a first mode, enabling at least a subset of first ADCs to perform a quantization operation of the voltages output by at least the subset of the pixel cells or blocks of pixel cells in parallel to generate a first image frame, each first ADC being associated with a pixel cell or a block of pixel cells of the array of pixel cells;
in a second mode, enabling at least a subset of second ADCs to perform quantization operations sequentially for voltages output by pixel cells or blocks of pixel cells within at least a subset of columns of pixel cells or columns of blocks of pixel cells to generate a second image frame, each second ADC being associated with a column of pixel cells or a column of blocks of pixel cells of the array of pixel cells; and
switching between the first mode and the second mode based on one or more operation conditions, the one or more operation conditions comprising at least one of: a sparsity of an image frame to be generated, a frame period in which the image frame is to be generated, or a constraint for resources to be used in generating and transmitting the image frame.
